Subject: 1.1 About this FAQ

This FAQ was compiled due to requests for various information that can
best be answered with a FAQ. It may help to reduce bandwidth for common
questions and problems relating to the Compaq Aero(tm). The authors are
not affiliated with Compaq Computer Corp, or any affiliate of theirs. We
own Compaq Aeros, and wish to help others with their questions regarding
the Aero. We hope to update this FAQ on a regular basis, but there are no

This FAQ is actually a collaborative effort from many individuals on
aero-l whose questions and answers were incorporated. Although
digestifying lots of posts results in a less authoritative style for the
FAQ, I believe it makes for a more spellbinding reading (e.g. watching
over somebody's shoulder as they disassemble the Aero and upgrade the
hard disk). Also, often there is more than one possible answer, or the
answer is not known (perhaps you know it?).

Undoubtedly there are still many bugs, errors, or obscure things in this
FAQ. You are welcome to send us your contributions/corrections or
suggestions. The usual disclaimer applies: the authors and contributors
disavow any responsibility for the information contained in this
document. If following the FAQ makes your Aero go up in smoke, do not
blame us (but, if it makes for good reading, tell us about it. Heck, tell
us about it even when it was not caused by the FAQ). You have been warned!

There are some stylistic differences between Ekkehard Rohwedder's FAQ
and mine. I have chosen to site my references by including some of the
mail header of the original posting (Date and From) when ever possible.
These entries are preceded by a [C] indicating the following is a
comment. Ekkehard Rohwedder used a [Q] and [A] format, with a big list
of all the contributers at the end. There are still some entries of the
old format left in the FAQ with incomplete attributions. I apologize if
any contributors have not been referenced in a proper fashion, and I
also apologize if I include an email address that was not intended to be 
distributed. I will seek to fix such problems quickly as they arise, but
as of yet, nobody has complained.

Doug DeJuio's  Aero is doing duty as the list server for this list:

Exactly correct.  This has been true for quite a while now (a few years).

> If so, I'd interested in details about your setup...

It's running Debian Linux, and using a LinkSys PCMCIA ethernet card to
connect to a T1.  It's got 12M of RAM and about 500M of disk, and it
just sits in a corner all day providing services.  It provides:
* mailing list server for this list
* web server (
* IMAP/POP and SMTP servers for my friends and family
* user accounts with shell access for my friends and family
* anonymous FTP (some Aero-related stuff) at

Running Linux, the Aero is fully up to the task of providing all those
services, even with just 12M/500M (though sorting and updating a mail
folder with >1500 messages in Pine can be pretty slow).

A little while back I basically destroyed my battery (it only holds a
charge for about 10 minutes now), so it's on AC power.  Also, someone
bumped into it in the machine room, and the battery door cover broke,
and it has since gone missing.  Also, someone bumped into the ethernet
card, and the transciever is now basically only attached with bubble gum
and string.

Subject: Unsubscribing to the mailing list

You should have gotten this information when you subscribed, and you
should have saved it for future reference. To unsubscribe, write to and in the body of the message put "unsubscribe aero"
or "unsubscribe aero-digest" and that should get you off the list. If that
does not work, get the help file by putting "help" in the body of the
message to majordomo.


Subject: 1.2.3 Companies that carry Aero parts and supplies

The aero has been discontinued for some time now. It has been increasingly
more and more difficult to find parts and supplies, but they are certainly
out there. If you do find them, you oftem find them at quite a bargain.

[C] Subject: Excellent service at PC Service - pass it on...
Date: Thu, 25 Jun 1998 08:53:43 -0500
From: "Brockwell, Stephen E." 

I have to pass on this info about the excellent service I received from
PC Service. ( )

Called them after noon on Monday this week and ordered a clutch hinge
for my Aero.  Price with shipping about $33  and was told that it would
probably be at my house by Friday.  It was delivered at 10 AM Tuesday
(less than 24 hours).  I live in Elgin OK and the part was sent from Ft
Worth TX.... about 180 miles away.  Longer distances may mean longer
delivery times.(your mileage may vary, etc)   After putting the part in
and making my Aero live again, I called PC Service at: 1-800-340-2667 to
tell them about the good job they did and to pass on the thanks to the
most senior supervisor I could get.  They seemed to be astounded that
anyone would call to talk about good service but they deserved it.  

A satisfied customer......

ed. note: Date: 2 April 1999, It seems that many people are very
satisfied with the folks at PC Service. As of now, they still have the
aero clutch in stock.

Subject: Re: Looking for an Aero

>Barnett's Cptr Whse(NY,NY) has a package deal -

I bought my aero from these bastards, and the whole business was a nightmare.
I would strongly advise no member of the list to deal with this company-they
are the most dishonest, rude bunch you will meet. It's not just me either:
comp.sys.laptops has nothing good to say about them.

Go somewhere else.

The Quantum ProDrive series drive does not require write pre-compensation,
your CMOS setting should be set to reflect that this feature is not
enabled. If the setting of 'none' is not present, the value 65535 is a
number that the BIOS will accept to disable this feature.

Jumper definitions 

Quantum IDE disk drives have multiple jumper setting options and are used
to set specific drive features. The most common settings are used to define
the drive as the primary or secondary drive on the IDE cable. [Master /
Slave] Quantum IDE drives have additional jumper settings used for optional
features found on the drive. Listed below are the various jumper options
that may be found on Quantum IDE drives and the corresponding feature that
they enable.

DS Jumper - Drive Select 

Used to identify the drive as the primary [MASTER] drive in a single or
dual drive configuration. This is the factory default setting. 

SP Jumper - Slave Present 

Used only when the second [SLAVE] drive in a two drive configuration does
not support DASP. DASP (Drive active / drive 1 present) is a CAM (Common
Access Method) defined signal that indicates the presence of a second
drive, DASP is used during power on initialization and after a reset. Prior
to this definition, products were introduced which did not utilize this
method to detect the presence of a second drive. The SP jumper is used on
the MASTER drive, with the DS jumper, when the second drive does not
support DASP. 

CS Jumper - Cable Select 

Only used in systems that support the cable select feature. Cable Select
allows for each IDE disk drive to be jumped the same and the position on
the cable determines the ID. This requires a special cable and both drives
on the interface would have to support this feature. 

PK Jumper - Park [Spare] 

This jumper does not enable any feature. It is used, instead, to provide a
spare location to any jumper removed from the drive during a configuration

Single Drive: DS only
Master Drive: DS only
Slave Drive:  No jumpers

Subject: 1.3.11 Video Controller

[C] Date: Tue, 17 Feb 1998 14:41:48 +0100
From: Markus Gebhard 

I have looked for something in the FAQ and happened to find the chapter:

   Video Controller

It is from Christian Rausch and I do not know when this informations
have been written down. But this informations are all pretty much out of
date, for we know much more about the Aero's graphics. It is all written
down at

Here is the peace of information most related to 1.3.11:

The 4/33c ueses a SPC8106F0b, not a SPC8108. It has 512k of RAM but the
model F0b of this chip is not able to access the upper 256k. The F0c
revision is able to do this but there is no Aero in the world with this
chip revision.

I think it would be a good idea to add a link to the video part from my
page at this place and to delete the last part of the text in 1.3.11,
for it only will cause confusion.

[C] From: Christian.Rausch
Date: 1996?

according to compaq:
the Aero uses a SMOS 8108 LCD controller from SMOS/Epson.


The SPC8108FOC is a versatile VGA graphics controller capable of
driving liquid crystal displays and analog CRT monitors. The
controller integrates all LCD interface, sequencing and gray shading
logic into one small form factor 144 pin package. With the addition of
an industry standard '477 type RAMDAC, the SPC8108FOC will also drive
a VGA fixed frequency or multifrequency monitor.

The target products for this device are price and power sensitive 80 x
86 microprocessor based subnotebooks or other specialized LCD systems
where a high quality 16 or 64 gray shade VGA image on a 320 x 200 to
640 x 480 LCD panel display are the major design criteria. 

I do not know if this really is the controller inside the Aero, since 
I haven't opened my Aero 4/25 yet (has anybody else looked at the LCD 
controller's label ? Please, tell us what's written on it! Has 
anybody seen the above mentioned '477 RAMDAC?).

The product brief above tells that the SPC8108 is a MONOCHROME LCD 
controller, but according to Compaq it's also used on color Aeros! So, 
maybe SMOS built a special version for Compaq, or Compaq uses some 
tricks to use the SPC8108 for the color LCD screen.

If the Aero's controller is the SPC8108 above, or at least similar to 
the SPC8108, then we're not lucky, because it seems to be restricted 
to 256k video RAM, which is not enough for 640x480x256(colors).
The other 256k are used, according to Compaq, for the 'pop-up feature when
coming out of stand-by' and seem to be inaccessible by the LCD

Hi John

You can easely fix the aero.
Mine had that problem some months ago and now is working ok

My 486/33  colour aero has a 1gb drive, 20 Mb of ram, a IR door and a

Subject: Ode to aero.


I just got this fuzzy feeling about my aero, and thought i'd write it

I like my aero very much. I bought it a couple of years ago, it was
mostly a coincidence. A freind of mine had one, and I immedeatly liked
its small size. 8M ram and a 386 seemd quite good back then. At first it
ran windows, and did that quite well. I never did big things with it,
just write a few text, the occasional small C program (using djgcc, if
anyone cares :) and playing a game every now an then. I had to lend it
to other people (including my mother) quite a bit, which wrote bigger
texts, while sitting outside in the green grass (albeit the display is
not very well readable in the sunlight). Then when I was converted to
'the Unix side' i didn't use it for about a year. Finally though, I
installed FreeBSD on it, and it got used a little more again. Taking
notes during lectures (this was where my 4M ram module got flakey and
triggered spontaneous reboots - i then bought a new 16M one)
And one or another small game. Actually I got X running (in the well
known modes) after some fiddling around, but am not very satisfied with
this. I prefer to use the console now. After some fiddling around I even
got it to spin its harddisk down on inactivity (unix does like to access
the disk every now and then). Then my Akkus (still the same from the
original buy) still last 2-3 hours, which is enough for the odd use
without an power outlet.

Now that I have an Palm III to take small notes, plan my schedule and
play a quick game, my aero didn't get unused, no. It merely got more
дinteresting' tasks. So it served my leased line, and acted as a router
for more than a week, when no computer was at hand (including the time
to set up) where it proved to be as reliable as any other server.
Actually this happend more than once, since it's just convinient :)
I can act as an DNS server, irc, web and ftp-server on small meetings
where we connect severeal laptops together. Possibly even connect all of
them to the internet via a GSM modem, and NAT (although i didn't yet do
this). Also it is a reliable Backup device for my pilot when I'm away.

All in all, I must say, that the aero was an worthy companion all the
years, and definitly made life easier. I have to admit, that it's
lifetime is definitly coming to an and (compaq even started to recycle
the name %-). Of course I will not trash it now, as it still does good
things, but I don't think I will put much more time in upgrades or
fixing things. Nowerdays, i'd just like to be able to run X without big
problems, maybe even play an mp3 file while traveling around, and all in
all be a bit faster.

Ah, btw. I didn't upgrade my harddisk from it's original 150 (not sure
now) Megs, and didn't yet break my clutch (*knocking on wood*) but the
display cable starts getting loose, as it flickers quite abit every now
and then.

Fare wall all aeronauts, for this is truely a great computer.

Failure is not an option. It comes bundled with your Microsoft product.

[C] Yeah, it's so bad that I just bought my second one! :-) No, honestly, I
LOVE this thing. It's just that the couple of recent problem threads on this
list represent real problems.

Nobody posts: "Ooooo! I love the battery life" or "Wow - Check that great
keyboard layout" or "Only 4 pounds - How did I ever live with that old,
heavier, laptop" or "Man, was this a great price for such a nice system" or
"Isn't it great to have an integrated trackball instead of one of them
lame-brained dongle-pointer-dealies that are forever falling off or getting
caught on stuff or rubbing on the side of the chair you're sitting in?" See,
nobody complains when everything's coming their way. Relax - it's a GREAT


Subject: 1.4.2 Opinions on Aero features (The Quick FAQs)

[Q] How much battery life can I expect (main use word processing). How
long to recharge? Is there a separate power brick and recharger?

[A] Up to 4 hours maximum and 1 hour to recharge. You don't need a separate
recharger but you can buy one if you wish to recharge two batteries at once.

[A] I get two to three hours runtime on my 4/33 color machine using
Windows. Recharge time is about 1.5 hours; but that's also using the
"extended" battery which ships with the color Aeros. Of course, recharge
time is longer if you're using the machine; but you can use it while the
battery is recharging. The AC adapter is not your usual "wall-wart" brick.
It's a block about 4.5" x 2.25" x 1.2" with an 18" cable to the plug which
goes into the Aero. The other end has a socket for the line cord that
plugs into the wall. This unit serves as both the battery charger and the
AC adapter. Extras are available for $29 or so; I bought a second one so I
can have one at work and one at home. Note that the battery must be
recharged while within the Aero. The optional Convenience Base has a
spot for recharging a second battery; without this you'd have to put a
spare battery into the Aero to recharge it.

[Q] What do you think about the ergonomic factors (e.g., screen size,
keyboard layout, trackball, etc?)

[A] Keyboard is great and silent. Screen size 8" is more than enough for
640x480 resolution screen. Think about it: on desktops people are using a
15" screen with 1024x780.

[A] I like them. Screen size is just fine for me. The DOS text-mode font
seems fine; better than some laptops I've seen. I like the keyboard more
than any other subnote I've used, and the trackball is fine. However,
these are all very subjective things and what works for me may not work
for you.

Subject: 2.1.2 Memory (RAM)


Subject: How do you upgrade?

Both the online help and the printed docs tell you how to do it. The Aero
can be expanded to 8, 12, or 20 meg of RAM. Going to 20 meg requires a 16
meg module, Compaq doesn't sell one. In any case, third party memory seems
to be a lot cheaper than Compaq memory, and I've seen nothing in the docs
which claims that using 3rd party memory affects the warranty in any way.
Note that there's only space for one memory module. If you buy a 4M module
(for 8M total), and later want to go to 12 or 20 meg, you must replace the
4M module.

sp1992 not noticing that it was a *patch* for sp1487. I was running a 6/94

attempted to install itself and then crashed. When I rebooted, it kept on
getting memory configuration errors. *Moment of panic*. My aero will not
start up. I kept on choosing the save-config option and after a couple times
through of recognizing/not recognizing the 20Mb of memory; it finally
booted. I quickly installed the full ROM upgrade sp1487 and since then have
not had any problems. *whew*

Subject: The tale of a journey inside

Note: this was the first story ever on an Aero disassembly. We now know
better and will not disassemble that one screw in the back that holds the
Aero display together.

[ this one is a bit wordy; but I felt it should go out to everyone on the
list rather than languish on an ftp site -- lrj ]

Just for the record, this was all in a dream. It is not true. I would
never do something as silly as opening up my Aero 4/33c, because that
would void the warranty or let the smoke out or something. Would I do
that? Of course not! cough If anyone were to consider opening up their
machine, remember that if you break anything it's YOUR fault. This is NOT
a trivial thing like opening up a desktop's case. If you're not (a)
willing to accept the consequences of something breaking and (b) confident
in your ability, then STOP HERE. Do not continue.


As a first step, shut down windows and turn off the power. I mean the
actual Fn+StandbyButton power-off sequence. Remove the battery. Find a
nice flat table and put something soft on it; make sure you follow proper
electrostatic discharge procedures. I reccommend a wrist-strap.

Remove all the screws from the bottom of the case, and the two from the
back of the right-hand side. (the two on the right-side back anchor that
side of the display, so be ready for it to become a little floppy :) THERE
ARE NO HIDDEN SCREWS. Happily, Compaq did not hide any under stickers or
anything. I used a flat-blade screwdriver, but the appropriate Torx driver
would be best.

Now you have to remove the plastic from the top; the stuff surrounding
the keyboard. It's a snap-down setup, and to disengage the clips you have
to push in on the top half while sorta pulling out on the bottom, while
lifting the top. Yah, one of those three-hand jobs.

ALSO: the speaker is one of those 3/4" piezo thingies that lives in front
of the trackball. Make sure it doesn't get smooshed or jammed into
something when you're popping the case.

There's one clip right next to where the battery cover goes, on the front
side of the machine. It's a good one to examine and get a feel for how it
works. The next one is in the middle of the front, right where the display
locks down.

The nasty one is on the right side between the back and the trackball
buttons. I finally got it by having the display up at 90 degrees, with the
whole machine sitting on it's left side. I inserted the corner of a credit
card between the top/bottom case halves from the back to put lifting
pressure on the clip as I pressed/pulled/etc. BE GENTLE HERE THOUGH,
there's definite breakage potential if you just force it. 

Next, there are a set a small tabs which hold the back of the top down.
You can see the line running under the display. Just kind of gently lift,
wiggle, lever, etc. 'til they pop out.

Now for the real fun; seperating the "top" from the display. I haven't
figured a good way to do it; as you lift the top over the hinges, it hits
the bottom of the display. Carefully applied flexing and bending (never
too much) was the only way I got the thing off of there. Just be careful
and look it over a bit.

At this point, your machine should still work. I figured I'd try mine
out, so I plugged in the AC adapter and powered it up. :) I of course
powered it down and unplugged it before continueing. :)

Next thing is to remove the keyboard. You'll find one screw in the middle
below the spacebar and three smaller ones across the top. That's it.
Remove 'em, tip the back of the keybd up and push backwards 'til it
disengages from the metal tab in the bottom right (closest to you). Watch
the two ribbon cables under it.

To disengage the cables, lay the keybd upside down over the battery 
compartment. You'll see a couple slider things on the two cable slots on
the motherboard. Pull the sliders towards you; now the cables will come
out easily and you can set the keybd aside.

In order to remove the hard disk, you must first pull out the flat cable
running across the drive, which goes to the trackball and buttons. Small
needlenose pliers are good for this if you're very gentle and go slowly.

One the cable's off, slide the hard disk to the right until it disengages
from the connector. Tilt the back upwards 'til it clears the motherboard
and lift it out. Voila! :) You could take the "carrier" off the existing
drive and put it on another 2.5" drive if you wished.

Reassembling the machine is pretty much the reverse of what I've
described. When reinstalling the hard drive, make sure that one "tab" on
the carrier lines up with the screwhole so it'll get locked down when you
put the screws back in. When you put the keyboard back on, make sure to
engage that metal tab at the bottom-right.

I would suggest checking the machine out before putting the plastic lid
back on; after the keybd's back on, plug it in/turn it on and make sure
everything still works. Then turn it of, put the top back on, and button
it up.

In summary, it looks like the hard drive is user-replaceable if you have
the confidence and ability to go in there and do it. It is probably not
something which Joe Consumer should try. I've broken a lot of plastic tabs
over the years as I learned how to finesse these things. :)

Put it this way; when it comes time to put in a 400-500M disk sometime
next year, I will be talking to the local service shop (which sells
Compaq) to see how much it'd cost to have them do the work. I am not sure
that I won't break a plastic tab or something next time.

Remember, this is all a dream. Nothing here is true. cough

Subject: Partitions

for information on recreating the diagnostics partition, see the section
of the FAQ that deals with the diagnostics softpack from COMPAQ.

[Q] Does anyone have any information on the little (2mb) partition which the
Aero boots from if you hold down the 'F10' key to run setup during boot? Is
there a FAT filesystem hidden there somewhere?

[A] The machine actually comes with two DOS partitions: the main one that you
see, and a tiny (2M) one which runs the setup utilities. You almost certainly
want to keep the latter around forever. As for the main DOS partition, it
contains lots of otherwise unavailable documentation about how your machine
works, and some setup utilities that do things that the setup partition can't

In particular, the utility to control whether the PCMCIA slot remains powered
during suspend seems only to be available in Windows, and at least a few of us
configured our machine to leave power on in the slot and are now regretting
that choice (because it uses up power during suspend).

[A] it has DOS 6.2 on it, and it has
config.sys/autoexec.bat files that run the setup program for the aero. You
install it by using the setup program, which you can transfer onto a 1.44MB
disk if you have the PCMCIA floppy drive. That's what I've done, seeing as I
don't run DOS or Windows but would like to be able to setup my machine without
a 2MB partition sitting on my drive doing nothing 99.99% of the time ...

84mb drive?

[A] Unfortunately yes. I claimed Compaq for that and they replaced my HD to
another 84MB and the new one was even worse.


Subject: Upgrading the hard drive

[C] date: 2001
from: Rick

First let me say that there is a lot more that I don't know about the Aero than
what I do. I have picked up a large number of these units and have
five of the 4/25 and two of the 4/33 working at this point. All of these units
have accepted the Toshiba MK1926FCV  814MB hard drives without partitioning.

[C] from Ingo Ralf Blum

I'm not Javier, however I had a UDMA-66 harddisk running well. The Aero doesn't
support UDMA, but the hard disks are compatible with earlyer standards, and so
they operate at PIO mode, which the Aero supports. Make sure you have the Compaq
setup disk available to tell the Aero the new harddisk size. The size of mine
was not automatically detected and I had to manually set the
cylinder/tracks/head values by hand. Have them at your hands. In some cases they
are printed on the harddisk, but sometimes you'll have to look at the
appropriate internet pages of your harddisk vendor.

> What size (gigas) is your hard drive?

It's 12 MB. When you ask, if the Aero can handle such drives, that depends on
which operating system you are using.
Usually there are the following dependencies.

Windows 95 -> BIOS -> harddisk
Linux -> harddisk

So you see Linux directly accesses the hraddrive and so supports all current
hard disk sizes. Windows 95 relies on the BIOS, and the Aero BIOS supports only
8 GB. This doesnдt mean, that you can't use larger disk on Windows 95, but
Windows only sees the lower part
of the drive.

Lets assume a 12 GB drive.


where each character is 512 KB. The # specifies the part which win 95 can see,
the rest is only accessable by other os which use direct acces, e.g. Linux.
So you can partition as follows.


where Windows has a partition in a lower part and linux in the upper. Contary
this doesn't work:


> What do you mean with earlier standars?

There are different operation modes of harddrives, PIO (programmed input
output), where the processor transfers the data, and DMA (direct memory access),
where the disk controller transfers the data (The terminology may not be 100 %
correct). These operation modes were introduced in the following order:

... perhaps the thats not fully correct
UDMA 100

The current drives are usually UDMA 66 or 100, mine is UDAM 66

If a controller operates only e.g. on PIO2 and you have a UDAM 100 drive, both
parties agree to the largest common protocol, which results in a PIO 2
operation. I think (however I do not know for sure) that all the older PIO modes
are also covered by the newest UDAM standards, so every drive should work.

> Does this mean that aero can manage an actually 6 gigas hard drive?

6 GB is no problem. As you can see 6 GB is well below 8GB so you can use it with
no restriction both in Windows 95 and Linux.

> And at last, you refer to a rompaq to set up the new disk, no?

Yes and no, I referred to a setup disk for the Aero. I can't remeber the fixpack
number, but it is named "Compaq Setup & Diagnostics". I is the same software as
usually installed on the harddisk, which you can execute by pressing DEL when
booting (I think it was DEL, but I have removed it, so that's a guess), but when
you install a new harddisk, there is usually nothing installed.

> (Somebody talked about don't touch the parameters and let the aero define them
by itsel, also if they're wrong, so the hard drive will work fine ?:)

That depends. Last month I replaced the 12 GB drive in the Aero with the old 170
MB, because I had to capture some video on my desktop and needed a drive. After
rebooting the Aero displayed "Bad system disk, press F1". This was, because the
hard disk layout was NOT automatically detected, and NO it was not an empty
clock-bios-backup-battery. So what I had to do was to go to Compaq's homepage,
find the disk layout (heads, cylinders, tracks), boot the Aero from floppy with
the setup disk and enter the values.

So be sure to have the disk layout of your current and old drive at your hands,
as well as a setup disk.

Another problem you should be aware of (Its not a really problem, howver it can
be annoying)

ATA drives don't distinguish heads, cylinders and tracks. They number the blocks
on the disk straightforward. However the BIOS does not and needs to map the CHT
values to block numbers. Unfortunately there are different mapping modes called
"NORMAL" and "LBA". If you have a desktop computer you can see these word
domwhere in your BIOS setup, where you can change them.

Here is the pitfall. When you format a drive in LBA mode, you can't read it in
NORMAL mode. Of course the data is still on the disk, but the block numbers map
to different positions, and so you'll likely get a "no system disk" error, when
booting. So make sure to always use the same mode. (In fact the mode is not the
problem, but the layout. Changing from LBA to NORMAL or the other way round
simply changes
the CHS values, so e.g. in one you have 8 sectors, 8 cylinders and 8 heads, and
in the other you have 2 cylinders, 2 heads and 128 sectors.
Both drives have the same size, but not the same layout.

If you format and install on your desktop and then put the drive into the Aero,
make sure you enter the values from your desktio into the Aero setup, if the
Aero doesn't detect the drive.

Formatting large drives > 8GB:

DOS fdisk (=Windows fdisk) relies on the BIOS to format drives, so you can't
format such drives on the Aero using the BIOS. Either install Linux first (or
use a Linux install disk, where a Linux partitioning program is on) or format
the disk in your desktop (which usually has a newer BIOS which supports larger
disks than 8 GB). Since noth methods don't know your Aero BIOS setting you'll
have to write down the CHS settings for your drive, for the case you have to
enter them into the Aero BIOS.

Nothing is more annoying than to have your computer in pieces and then find,
that you need some data which is on your pc's harddisk or in the internet.

Yeh! I've just installed a Fujitsu MHD2032AT disk (3.2 gigas) in the litle
Aero! now it is a big boy!
Somebody told that Fujitsu discs were a little bit problematic to fit in the
aero because of the drills of the cady. He was right! but I had already
ordered de disk ;) But it wasn't a mission impossible! I just used car
painter tape (Sorry for the literal translation), to make the "paper
Spacers" that evite the disk from moving off its place.
Thanks everybody for the advices about bios, and setup floppys (Uf!). The
setup program just detected the disk, size, cylinders... and if I tried to
modify them, they reset to 0 (Oh my God what a fright!). So I reset and
didn't touch the parameters (That were right by themselves), and it worked.
After I used the W95 instalation disk to format the drive. I must say I've
just left 500 megs to windoze, and the rest for LINUX (I said the AERO is
now a big boy, no? :)
What a dream! Is a little dificult to know when it writes (Because it is
less sonour than the original quantum daytona). It wakes up faster. Tomorrow
I'll install de OS, so one day of thees I'll measure the performance of the
drive, ok?
Bye Aeronauts of XXI Century!

Modern harddrives are much faster that the factory installed 84mb and
170mb drives that were shipped with the aero. They are also much more
reliable, hours-of-operation-wise. Two good reasons to upgrade, in
addition to the obviuos gain in storage space. The increase in disk
access time can make the aero run much faster. 

If you are installing a large harddrive, you will also want to upgrade
the system ROM to SP1992 so that the Aero can recognize the larger
drives. If you do not, you will have to use some interleaving software to 
access the larger harddrive.

It can be done.  The suspend/maintenance partition may be a problem and
since you don't have a floppy that will be necessary.  You can install an
operating system byu using a 2.5 -> 3.5 adapter and set up the drive in a
desktop computer.  The carriers are listed in the aero faq and also are
now available from

Subject: fdisk and Partition Magic only see the first 500 MB or so.

Aeronauts--Help, please, with this one.  Many of you have reported installing
drives of various manufacturers greater than 540 MB, even > 1G, _without_
having to resort to Disk Mangler to overcome that barrier.

I had a Toshiba MK 1924FCV 540 MB that I needed to replace as it was full.
This is a _dog_ of a drive, so I was eager to do so.

I have it replaced with a Maxtor MobileMax 1.35G drive, but guess what?  
Even with the latest Compaq bios, and even though the bios sees all 1.35G,
both fdisk and Partition Magic only see the first 500 MB or so.

What gives?  BTW, the diagnostic partition installed perfectly.  The drive,
based on its interactions with the diag. partition, is much quicker and
quieter than the Toshiba it replaced.

First wipe all fdisk stuff off. NO Diag Partition no MSDOS/windows Partition
NOTHING!. Then Boot with first Diag disk in. and set the drive up under the
setup there is a disk icon under that there is advanced under that there is
another tab which specifies which operating system. Click if DOS/WINDOWS
click Other. Then exit and let the machine reboot. Then go back and reset
the tab to DOS/WINDOWS this feature is what turn on LBA translation which is
what ONTRACK Overlay manager does. I also want you to know you must be on the
latest and greatest BIOS and DIAG utilities other wise things may not work. 


PS Just a suggestion I am not liable for anything that may go wrong from
following these directions.

  -- Ed. Note: For those of you who wonder why you can not get much more than
500 Mb of HD on your Aero: The BIOS when running DOS or windows 3.x can 
only recognize 1024 cylinders. This usually works out to about 502 or 512 Mb
depending on the rest of the hard drive parameters. You can get around this
by using either a special driver or a utility. If your hard drive needs this,
then one then contact the distributor or you can use the previously described
method for gaining full access. It is interesting to note that LINUX is not
limited in this way.    - Philip

  -- Ed. Note: The harddrive can be no thicker than 12.7 mm.  - Philip

[A] I would like to share my success in swapping out the original 170 MB disk
for a 353 MB disk in my 4/33C. I just carefully took the Aero apart (take care
with the clip on the right side), pulled the Seagate ST9190AG drive from its
carrier, put in the new one, and put it all back together (and fixed a slightly
erratic graphics cable along the way). I was mighty impressed with the
technology in there.

Now for the setup. I had made a floppy version of the Setup and Diags
partitions ahead of time and proceeded to use these to set up the
cylinders/heads/sectors and run a full diags sweep of the disk. I made three
partitions on the new drive -- 50M for DOS, 30 MB for shared swap and the
remaining 273 MB for Linux. I didn't make the diags partition; I'll just use
the floppies again if I ever need something from the there again some day.

So, it can be done. I was a little hesitant at first after calling Laptop
Solutions in Houston because they tried to tell me the BIOS wouldn't support
different sized drives without their proprietary changes. Well, maybe there are
cases where their changes are needed but I've not found them yet.

The drive is a Toshiba 1824FCV (682 cyl, 16 heads, 63 sectors); I just
reprogrammed the drive type 65 entries with these values. Only down side is
that it seems to spin up a bit slower than the old drive. But I'm convinced the
battery life is better, at least a little. The noise is distinctly different
too; maybe a little lower pitched but still as loud.

Warranty? Well, yes, compaq tech support told me what I did voids the
warranty.He said my only option, if I need service, is to put back the old
drive and tryto convince them the problem is not related to the change. I'm not
worried about it but it might be a factor for some.

[A] I can second Elwood's story. I have had the Toshiba disk in my Aero for
about 2 weeks now. Its great to have 330 MB of disk. Also, I think Elwood is
correct, in that the battery lasts longer with the Toshiba disk. Seems to draw
less power.

The difficulties I had in doing the exchange were much the same as Elwood
related. Namely the clip on the right hand side next to the mouse buttons. In
addition, I could not get the cable unplugged that feeds the trackball, mouse
buttons and speaker. So, it was easy enough to unscrew the track ball assembly.
The speaker, buttons and trackball could then be lifted out of the way while
still plugged in. Also, Ali, your instructions to me on not removing the lower
screw supporting the screen were correct. It is not necessary and helps keep
the assembly stable while trying to pry the cover off!

The Toshiba drive cost about $400 with tax. I bought it from Micro Sense in San
Diego, CA. (Micro Sense's Phone number is 1-800-544-4252.) They were very
helpful in telling me that the drive would work in the Aero without any BIOS
mods. They also told me I could put in a bigger capacity drive, but I would
need some BIOS mods to do that.

[Q] After saving the automatically recognized drive parameters, how did you get
FDISK to run on the PCMCIA FDD? I thought the PCMCIA drive needed drivers
loaded before it was recognized or is that something that's built into the BIOS

[A] Yes. The FDD runs out of the BIOS. You can boot from it with nothing on the
hard disk. This assumes you have a current COMPAQ BIOS too. Very old ones did
not support the FDD correctly.

A word of warning. When I took apart the case it took me 2 1/2 hours. I was
very careful. I stopped twice during the process because of frustration.
However, once the top of the machine is off, then removing the old disk is not
a big deal. You move the drive holder from one driver to the other. Push the
new drive into place on the connector.

You can then power up the machine and test it to make sure the disk works.
(Have a boot floppy with FDISK.) If you have done it correctly, you will see
lots of disk space. Putting the cover on only took 10 minutes. The hard part is
prying the cover over the screen support rods. Also, do NOT remove the bottom
screw as seen from the back of the Aero which supports the screen. The screen
is really loose if you do this and as Ali told me, you can tear the flexible
cable that goes to the screen!

As has been said before, this is not for the faint of heart. If you take your
time, walk away from it if you get frustrated, and do not force anything very
hard you should be OK. The most difficult part is the clip near the mouse
buttons. If you do not have the original case disassembly instructions, I can
resend them.

[Q] Which brand(s) and model(s) can replace the 84Mb and 170Mb drive in the
Aero 4/25...anyone know if the drives are higher than the drives sitting in the
4/33c or is the height difference merely the colour screen as opposed to the
mono screen?

[A] Correct. The height difference is in the screen and not in the base. The
Toshiba MK1824FCV was an exact fit at 12.5mm. The Toshiba has 335MB on it. It
should also work in the 4/33c. The drive in the color model is the same size as
in mono. They're both 2,5" slim IDEs.

Subject: Installing MobileMax: A How-To

It looks like a number of aeronauts are about to embark on installing a Maxtor
MobileMax 1.3G drive in their Aeros.  I have had one in mine for about two
months; here are my installation tips:


DISCLAIMER:  I'm not responsible for the consequences of your following these
suggestions.  They worked for me, but I have changed out many a notebook
hard drive.  If you think what follows is beyond your skill level, get someone
to do it for you.  And regardless, ANY disassembly of the Aero presents even
an experienced person many opportunities to ruin the computer inadvertently.
In addition, the following procedure will surely void any warranty you have
on your Aero.


Make sure you ground yourself when dismantling the Aero, and especially when
touching the hard drive.  Wear a wrist strap that is grounded, or repeatedly
touch a well-grounded object during dismantling and reassembly.

1.  Make sure you have the latest ROM upgrade installed on your Aero.  Check
the Aero FAQ for where to get it if you're not sure.

2.  Be sure you have Compaq Setup Disk 1, SP2054, and Compaq Diagnostics Disk
2, SP2373.  These versions appear necessary to allow all 1.3G of the disk to be
seen during fdisk and format (there may be an earlier version that works, but I
_know_ these do.  Check the Aero FAQ for locations if you don't have them.
Make sure the disks work by running them before proceeding further.
3.  Familiarize yourself with the disassembly procedure outlined in the FAQ for

    - note: The harddrive replacement tutorial should be the section 
      following this primer. (Subject: A step-by-step 
      tutorial) - PW

4.  Do _not_ remove the lower of the two screws on back of the Aero next to the
external power supply jack.  As the FAQ notes, it isn't necessary and will
greatly increase the chances you'll damage the video ribbon cable or other
parts of the display.

5.  I recommend removing the bezel surrounding the screen, as it makes removal
of the upper case half of the Aero much easier.  See the FAQ for details on how
to do this.  Work slowly and carefully, and don't force anything.  Then, remove
the upper case half--again, see the FAQ (as there is no point in my repeating
all of that here).

6.  Once the upper case half is removed, unscrew the small screws securing the
keyboard, and fold it over toward you.  Do not disconnect the keyboard as it
isn't necessary.  Be very careful not to stress the keyboard ribbon cable. 
Just let the keyboard lie flat in front of the Aero.

7.  Remove the long screw securing the drive carrier to the Aero.  Do not try
to disconnect the ribbon cable which runs across the top of the drive and then
makes a right angle turn towards the trackball.  It is very easy to damage.  
Instead, unscrew the trackball housing.  Before lifting the assembly up, pay
particular notice to how the purple trackball buttons fit in the side casing,
as you'll need to put them back exactly that way.  Now, lift the trackball
assembly, purple button assembly, and ribbon cable, all attached together,
and lay them over on the left side of the Aero.  The drive can now be
accessed for easy removal.

8.  Carefully grasp the drive and pull it straight back, then lift it by the
THE DRIVE OR ANY OF ITS CONNECTORS.  Handle the drive by its sides only.

9.  Notice how the drive carrier is screwed to the old drive.  Unscrew it and
attach it in the same way to the MobileMax.  GROUND YOURSELF WHEN TOUCHING
MobileMax's static bag for safekeeping.  Check with DALCO for inexpensive
adapters to let you use your old 2.5" drive in a desktop (see the FAQ for 
parts numbers and phone).

10.  Place the MobileMax with carrier properly attached in the Aero, and slide
it firmly forward until it stops.  Replace the long carrier screw.
Reassemble the trackball/purple buttons asssembly.  Be sure those buttons
go back in the right way, or you'll mash their connector when you replace the
upper case half.

11. Check to make sure the keyboard cable did not pull out of its connectors,
and that the video cable is also firmly attached.  Place the keyboard back
in its location and attach the small screws.  Do not replace the upper case
half and bezel until you see if the drive works--otherwise you'll just have to
tear into it all over again.

12.  Insert the floppy drive card into the PCMCIA slot.

13.  Put Setup Disk 1 into the drive (SP2054).

14.  Apply external power (DON'T use the battery--it could fail during this
critical setup) and turn on the Aero.  It will boot from the Setup floppy
if you have properly copied to the disk.  You should hear the MobileMax power
up.  It has a strange, two-stage spinup that sounds something like a car
shifting up through gears (at least, after it is installed properly).

15.  Follow the directions on the screen.

NOTE:  After you fdisk and format the drive, you will not have 1.3G, but
something less (1280MB or therabouts).  This is NORMAL; you're not being
cheated by Maxtor--it has to do with how formatted disk space is calculated.
So many people freak out when they see the "missing" MB's.  Don't worry!

If you find that you cannot get fdisk to recognize more than 500 MB or so, it
is almost certainly because (a) you do not have the latest ROM upgrade and/or
(b) you don't have the proper Setup/Diagnostic disks.  Get the right ones and
things should work.

16.  Replace the upper case half and screen bezel, and enjoy that fast little

Finally, you don't need Disk Mangler or any other dynamic disk overlay program
to use the full capacity of this drive.  It just isn't needed, and will add 
many complications.  Don't use it!   The Aero's latest ROM bios fully supports
the capacity of this drive.

From: Bill Flynn 

with modifications by Philip Wilk

I just upgraded my Aero 4/33c's hard drive from 170mb to 720mb. This process
was remarkably simple. The new drive is an IBM DBOA2720, 12mm 13ms. It was $699
from Micro Sense, CA (800)544-4252. I run Linux and the X Window system on this
and maintain a small dos partition for maintenance tasks not accesible to
PC-UNIX (essentially, a 640k PROM ;-<). I summarize the process below.

These is a procedure that I followed to replace my drive. Use at your own risk.
Replacing your own hardware may likely interfere with your Compaq warranty. I
can not be responsible for any damages incurred should you set out on this

Before removing drive

  1.  Go into Compaq setup by pressing F10 on bootup when the cursor goes to
     the upper right corner of the screen.
  2.  Select the option to "Create a Diagnostics Diskette". From here feed the
     required diskettes and then feel safe that you will be able to restore
     this neat little setup partition. NOTE: The setup partition must be the
     fist partition on the hard drive so it must be installed before making any
     other partitions!
  3.  Go into "Computer Setup", then into "Storage", then "Configure Fixed Disk
     Drives". Write down the all information under "Fixed Disk Drive
  4.  Back up any data you need to secondary media ;*)

Drive installation

  1.  I strongly suggest using a grounding strap. These should be available
     from local electronics or hobby shops, if you dont have on already.
  2.  Carefully disassemble the Aero. There are 4 screws on the bottom, and two
     in the rear. All the screws to be removed are black.

Date: Tue, 18 Jun 1996 17:05:05 -0500 (CDT)
From: Peter Barrette 

   I would like to make a correction in the HDD replacement instructions. 
Step 2 has the user removing both of the rear screws. Only removal of the 
top screw is neccessary while removing both can create difficulty in 
handling the screen. 

  3.  There is a "shell" surrounding the keyboard which snaps apart in the
     front. Be careful not to scratch the case if prying this with a sharp
     object. This peice is somewhat difficult to remove from the hinges of the
     display. BE CAREFUL with the ribbon connecting the LCD display to the
     internal assembly.
  4.  The system board and hard drive are located under the keyboard. Unscrew
     this again being careful with the ribbon cables connecting the keyboard to
     the system board. The keyboard can be laid toward the front, out of the
  5.  The hard drive can now be accessed. It slides away from the system board(
     to the right). Once disconnected, it can be lifted out. Lift it out front
     first or the screws on the back may put too much pressure on one of the
     circuit boards. There is a vertical tab on the disk mount which has to
     clear the ridge across the front of the aluminum system board mount.
  6.  My IBM drive came with one jumper installed. Without this jumper, the
     system didn't recognize the drive at all. I left it off as the 170mb
     Segate had pins in the same position non-jumpered. I suspect this has to
     do with the IDE master/slave stuff. (my drive expertise is more with SCSI
     drives on UNIX workstations and servers).
  7.  If you are using the IBM DBOA2720, it's drive parameters should be on the
     drive label. Mine are as follows: Type: 65
     Cylinders: 1400
     Heads: 16
     Sectors: 63
     ECC: 4
     Capacity resulting from above = 722.0 MBytes
     1400cyls * 16heads * 63sectors/track * 512k blocks = 722534400bytes
  8.  Switch the drive bracket to the new drive.
  9.  The installation is the reverse of removal keeping in mind the following

AGAIN, BE CAREFUL WITH THE RIBBON CABLES. Be sure they are all fully seated in
the sockets. When I put mine back together, the display cable was not fully
seated and upon power on, the screen went blue with BRIGHT yellow lines. I then
reseated the cable and when the system came up, the yellow lines were etched
into the display. Fortunately, these gradually went away by the next day. The
display was only up for about 5 seconds like this. I suspect much more may have
fried it so again, please be careful.

      Use caution reassembling the "shell" surrounding the keyboard.
      The first time the system is booted, it will notice the drive and ask for
      confirmation before updating the CMOS drive parameters. Allow this.

Reinstalling setup Boot system the first time from the "setup" diskette. It
will notice that the new hard disk has no diagnostics partition, and suggest
that you create one. Select the option to do so.

Good Luck.

useful to someone.  Roadwarrior's # is 1-800-274-4277.

Portable enhancement products also carries an adapter that is not listed on
their web pages Tel: 800-737-7693 or 714-418-0113
I have not seen this one and I don't know if it interferes with the jumper

From: Markus Gebhard

The 2,5"-drive connector has 44pins, this is 4 more than the AT-Bus. They
can be connected by using an adaptor.

I first thought they were counted one row down and the other row up, but
as I found out the standard way is like this:

             1 o o 2
             3 o o 4
             . . . .

             . . . .
            39 o o 40

so the pin table has to be:

          44pin:             40pin:

           1 - 40             1 - 40

           41, 42             +5V (red)
           43                 GND (black)

           44                 N.C. / Jumper??

[C] Phil--I wrote the little part in the FAQ.  I don't know the pinouts, but 
there are really cheap alternatives to what was in the FAQ available now:

DALCO  1-800-445-5342

48760  2.5 adapter cable w/PS connector            $9.50
48755  2.5 hard drive adapter w/PS connector        5.75
50960  2.5 drive ribbon cable                       4.85

If your time is worth anything, these prices should discourage you from
making your own cable!

48760 is 48755 with a 12" standard IDE cable.  48755 is just the
adapter, to which you would attach an ordinary IDE ribbon cable leading from
your 3.5" drive to the adapter.

Yes, PS means a power supply connector (the kind that would plug into a
standard computer power supply lead.  Only two wires are attached, of course
(for +5V plus neg.).

An adapter for attaching a 2.5" notebook hard drive to a regular desktop's
IDE cable is available for $14.95 + COD charges from DD&TT Enterprise, Inc.,
5680 Rickenbacker Rd., Bell, CA  90201.  Their phone number is 213-780-0099.
They will not ship on charge cards, only CODs, which adds about another
$9.00 to the overall price via UPS.

The part # is DT-1958.

The adapter includes an aluminum carrier that allows you to screw the 2.5"
drive onto the carrier, which will then fit into a regular 3.5" drive bay.

My adapter worked flawlessly on an 84MB Quantum HD that I took out of my
Compaq Aero when I upgraded to a 540 MB HD.

NOTE: this adapter also plugs into the right four pins on the 2.5" drive,
which may pose a problem if the drive needs to be jumpered (you can add jumper
pins to the DT-1958 if you don't mind soldering--look closely at the diagram
that accompanies the adapter).  
Another source for an adapter, which does not cover the right four pins and
thus allows you to use existing jumpers on the 2.5" drive if needed, is sold

PS Solutions, Inc.
1800 N. Glenville Dr.
Richardson, TX  75081
214-783-6997 (fax)

I paid $15.00 per adapter for two, plus $3.76 shipping.  The part number is

PCB 2.5-3.5-I

Unlike the DT-1958, no carrier is provided for the 2.5" drive to fit in a
3.5" bay.


Subject: Fixing the Master Boot Record

From: Philip Wilk
Date: 30 June 1996

So you diddled with your master boot record huh? A good way to futz things
up is to use LILO followed by another program that tries to "fix" things.
The problem is that your second program will get awefully confused by LILO
and to punish you for straying from the Microsoft Path by making your 
computer unbootable.

To fix things, type "fdisk /MBR" from DOS, where MBR stands for master boot 
record. This will fix everything, or at least it did for me. Thank you Ryan
Davis for letting me know about this.            -Philip


Subject: Christian's Aero harddrive upgrade list

The current list can be found at:

Aero harddisk upgrade list Ver. 2.7: (April 23, 2002)

All email addresses have been obfuscated by changing the "@" to "-at-".

This list is intended as an aid for Compaq Aero users who want to upgrade 
their harddisks in choosing the right one (of course, without any 
guarantees). Note that only 2.5 '' IDE or EIDE harddisks with heights of
less than 12.7 mm fit into the Aero. Read also

on the Aero page of Philip Wilk

before upgrading your Aero. It helped me a lot.
Please send any comments on (hopefully) successful (or unsuccessful)
harddisk upgrades to Christian Rausch (
I will add them to this list as soon as possible.
If you have time, then please check the performance of your harddisk 
with cthdben.exe from the German c't magazine. It can be obtained via ftp

and reports the weighted average and the minimum/maximum  transfer rate
of your harddisk. Note that you should use plain MSDOS (no emm386 loaded,
no smartdrv or other caches loaded) and your disk should be as 
unfragmented as possible to get meaningful results.
It would be best to run this program right after installation of your new
disk. Please tell me the min/max and avg transfer rates of your disk then.

------------------------------ External harddrive solutions

[C] Philip Wilk, 06-Feb-97

There are several companies out there that sell kits to convert 2.5" or
3.5" harddrives into external harddrives. This can be either by PCMCIA or
Parallel. I think the best best company is H45 Techonologies, this is the 
one I use. They can be found at or 1-800-220-6346. You
can also order from  PC-Connection. Right now the parallel kit is $98 and
the PCMCIA kit is $98, but the the PCMCIA kit requires an additional $100
PCMCIA card from this company. They have drivers for Win 3.1 and Win 95,
and possibly others.

Subject: The pulsing backlight puzzle

[Q] Has anyone noticed that, when running on AC with a fully charged battery
pack inside, the backlight gets noticeably brighter and dimmer at three second
intervals for about a minute every hour or so? I've got a 4/33C with the
extended life NiMH battery, and thought it might have something to do with the
battery being "topped off" when already full. The symptoms disappear when
running on AC without the battery pack, with the battery alone, or while the
battery is charging.

[A] I have the same problem and I do like you when it appears, I disconnect the
power supply or put away the battery.

[A] I experienced the problem under the MS-DOS 6.2 which came with the system.
I was watching it for a while last night; 70 pulses, each lasting about 1

In my experience with 3 Aeros, this is a sign that the solder joints on
the screen connector [on the mother board] have broken. If you have a
very fine soldering tip and are a very good solderer, you can remove the
motherboard and resolder these connections. This will resolve the

Subject: reattaching the screen cable properly

I had my clutch break on me, and then when replacing the clutch, my screen
cable became detached from its socket near the keyboard. I reattached it
with success, but later I began to have connection problems (the screen
would get lines and static in it).

In attempting to improve the connection, I ended up tearing the cable,
which I am now replacing.

I have learned that I was reattaching the cable in the wrong way.

I am not sure if the proper way is noted in the clutch and screen
connection sections of the aero faq, but it might be good to add this note
in a prominent place in relevant sections because I did not notice
warnings about reattaching the screen cable when I read the faq.

The proper way to reattach the screen cable is (I think):

After removing the plastic cover that sits around the keyboard, unscrew
the keyboard so it can moved out of the way in order for you to have
easier access to the socket.

Then, there is a little grey plastic piece with a slit in it sitting over
the socket. Take this off the socket and slide the cable through the slit. 
Then stick the cable in the socket and slide the grey plastic piece down
until it snaps in place. The cable should be snugly attached to the socket

The grey plastic piece is essentially a little wedge which presses the
contacts on the cable close to the contacts on the socket, and also holds
the socket in place.

The connector is actually a slide/friction thing.  It's possible to put it
together and have it ALMOST right.

Next time you have it apart, look closely at the two little tabs on either
side of the plastic.  Use those to pull half the connector away from the
circuit board.  BE CAREFUL - it only moves about 1mm.

Then slide the cable in.  When the cable is all the way down, push those
two little tabs toward the circuit board and you should be able to see that
the cable is now crimped, sort of, and shouldn't slide away.

FWIW, I've had my Aero almost since they came out with it, and have never
had a problem with the connector IF I had put it together right.

That solves my mystery of what to do with the little metal clip. I
thought it was there as some sort of shielding clip to maintain
continuity between hard disk and the chassis. 

I did notice my Aero cable was on the loose side. Next time I have to
take mine apart I'll put the clip back where it is supposed to go.

Denis: I had the same problem, so I took screen casing down and tightened
up the clutch screws and it was better....for about a month and
I've noticed screen casing loosening up again, did you try tightening the
screws?  I've got a feeling it's got something to do with too much flex in
the screen casing affecting connections in LCD, just a guess.

... try pressing firmly on the ramp on the
case just above the F3 and F4 keys. If this causes the display to light, then
the contacts on the cable from the screen to the motherboard are dirty...

[Q] My 2 month-old Aero 4/25 monochrome recently developed a "loose connection"
in the wiring between the screen and the CPU so that the screen blanks out when
the clamshell hinge is opened...and the screen works only after you open it
almost fully and then slowly, carefully bring it back to about 110 degrees. The
backlighting still works. I just get a bright, blank screen. I've called
Compaq's product support here in Canada, and they've told me that the "tape
that holds down the ribbon that goes to the screen probably became unseated
within the hinge," and they would fix it under warranty. Has anyone else had
this problem?

[A] Yes. When I opened the case of Aero that ribbon-like cable slipped off the
hinge. I doubt whether it ever was properly seated. Ask them to replace it with
a longer cable if they have one. The original one is definitely too short.

better. I think that the assemblers used their fingers a lot on the screen when
they assembled them. If you get a nice soft wide FLAT object and rub it across
the screen you can smooth this out somewhat. If you poke your finger on the
screen it will mush out the "LIQUID" in the LCD, and make the screen lighter at
that point. You can use this to your advantage to "even" out the liquid a
little bit. Mine was really spotty from the assemblers fingers, but looks MUCH
better now.


Subject: 800x600x16 VGA mode

As of yet there is no driver avaliable that provides this mode for an 
external monitor, but there is a healthy amount of speculation out there that 
it is possible. The aero's built in screen does not have the physical 
capacity for such a mode.              - Philip

[Q] The on-line documentation states that there is a video driver available for
the Aero which will support 800x600x16 windows video on an external monitor on
the Aero subnotebooks. This video mode would require ... (800x600)pixels x .5
bytes/pixel= 240k video ram (4 bits required per pixel for 16 color depth).

The Aero has 256k of video RAM. This should be doable according to the math. It
is also mentioned in the on-line docs under the section which deals with
"External VGA Monitor connection", but Compaq tech support has disavowed any
knowledge of this driver. When I point their tech support to the mention of it
in the on-line docs, they just say it must have been a mistake. I think they
just did not get it out the door, and no one has pressed them enough to get it

Compaq tech support also could not provide the video chip manufacturer, or chip
number, and the tech had no idea what chip it was other than telling me his
docs just said "SLSI video ". I believe that the chip is a Tseng Labs ET4000,
which is capable of 800x600 support.

[A] I have a couple of reasons to think that 800x600x16 WOULD be possible, at
least in theory.

      Back when I owned a 286 desktop machine, I had a Trident video card with
     256K of graphics memory. I was able to do 800x600 graphics in 16 colors.
     In fact, I had Windows drivers (at the time, Windows 3.0 would work on a
     286 in real or standard mode, just not 386 enhanced mode) which would run
     the display at 800x600x16.
      In Fractint (DOS version), I remember that there were several video modes
     supported which entailed reprogramming the video hardware; if a VGA
     chipset is register-compatible with the IBM VGA spec, then in theory those
     chips can be reprogrammed to display 800x600x16, whether or not the chips
     can natively handle that resolution! Such tweaked modes worked fine on my
     286 system, although the aspect ratio was a little "off" (i.e., the screen
     was squashed a bit). Naturally, the native Trident 800x600x16 mode looked

As I said, I was able to get 800x600x16 video on my 256K Trident card. Whether
this will work on the Aero's external display remains to be seen -- the VGA
chip in the Aero might not handle things the same way as the Trident chip(s).


Subject: Special supported 256 color VGA modes

[C] Date: 8 May 1997
From: Philip Wilk

Markus Gebhard has compiled a lot of
information about the 256 color barrier on the aero. These data can be
found at: <>.
Basically, the gist of it is that there are many different video modes
avaliable to the aero. Some of these video modes require an external
monitor that is about to sync at specific, non-standard frequencies. So
far, the only viewer program that can access these video modes is
fractint, which can be found at:
Also, you may want to check out the 640 x 480 video mode that uses 16
greyscales; according to Mr. Gebhard it looks great. The only downside is
that some of those modes require a 45MHz H-sync. Not all monitors can do
this (mine can not).


The Aero does provide support for the "unofficial" 360x480x256 mode which is
available (if undocumented) on most video cards. I'm not sure of the mode
number, but I know that it runs full-screen rather than as the chopped-off
320x200 mode. Remember, on an LCD display you can't change physical display
resolution, so things that don't divide into 640x480 evenly (like 640x200,
320x200, 320x400, etc...) are going to get chopped off. 360x480 is in my
opinion a far better solution than 320x200, assuming your program supports it.

[C] Date: Tue, 16 Apr 1996 13:42:38 -0700
From: Steven Lawson 

You can't get 256 colors in 640x480 mode because not enough video
ram is available (only 262144 bytes is available, 256 colors needs
307200 bytes).  This eliminates hi-res Windows and anything else
needing 640x480.  You CAN get 256 colors in DOS with certain
image viewers in a 360x480 mode.  Compushow (CSHOW) does this
very well and it's what I use.

There's also a viewer for Windows someone on the list mentioned
which does a pretty good job dithering with 16 colors.  I've
played with it and it was the best I've seen under Windows, but
still nowhere near as clean as CSHOW under DOS (or a DOS session)

This is the biggest limitation of the Aero.... :(

   Note: I think the program for windows is lprint.   - Philip

[C] From: Miguel Angel 

Many people in the Aero list have said that they cannot recognize photos
while they are in Internet. Well, there is a trick I use to view them in 256
colors; I use a picture viewer called PV, in the Netscape helpers you can
set the JPG and GIF (and all the others) to launch this application that
runs in Dos, and when you click with the right mouse button to view a
picture then launches the PV in Dos and I can view the image in 256 colors
in low resolution.
I don't know exactly where I get this application, i think I downloaded it
from and it works great with all formats. 
Best regards.


Subject: Special supported text modes?

It all depends on the number of vertical lines. On a CRT display it doesn't
matter how big the screen that is projected by the guns is, the phosphors will
be lit where they get hit - hence you can display 640x480, 640x400, etc in the
same vertical sized screen, the pixels are in no fixed position on the front of
the display On a LCD display such as your Aero, there is only 480 vertical
lines of display, and each pixel is fixed - you can't display 400 lines over
the whole of the vertical screen without some rows becoming 2 physical lines,
which would be a hassle to implement and would look terrible. The result is
that when you use other than a complete multiple of 480 vertical scan lines
then it displays it on only 400 or so of them, and centres those used
vertically, resulting int what you were describing. In my travels, I've found
that either one of 43 (EGA) or 50 (VGA) vertical lines have produced a full
screen of text... try one of those.

It should go between the bar of the clutch and the head of the screw.  
The bottom hole (the one closest to the keyboard with the screen open) is

I just picked up my new Aero (4/25) clutch today. The spring mechanism is 
the same old stuff; spring steel wrapped around the axle to provide 
friction. The difference is in the part that attaches to the monitor. The

one where the breakage occurs), but it is the same thickness as the old

The process of recieving my new clutch went like this:
    Step 1) Go to compaq dealer. "What's that thing called?", "A clutch."
            "Are you sure that's the right part number?", "Yes."
            "That's not in our computer.", "It's the right part number."
            "Well, if that's the right number we'll order it and it will be
            in about 3 weeks from now.", "OK."

    Step 2) Go to compaq dealer _one_ week later. Pay $33.60 and walk out
            with new clutch.

I have found that getting the CPU cover off is much easier if the display 
bezel is removed first.

Yes, I am not covered under the three year warranty since I bought my 
Aero used. I also did not want to pay $80/hr to my local compaq dealer 
for "labor". I ordered part number 185099-001 and received the "clutch 
kit" for $33.60 including tax. The kit included:
   * The reenforced right clutch
   * One screw to attach right clutch to screen
   * One axle for left hinge (attached to screen by 2 screws)
   * One collar to connect axle to base (slips into collar on base)
   * Two screws for left hinge axle
   * Improved metal hold-down for screen cable (holds plastic lock in place)
   * Two screws for screen bezel
   * Two black adhesive disks to cover screw holes on screen bezel
   * One black screw to attach right clutch to base

All screws (except the black one) had coated threads to prevent them from 
twisting out. The metal hold-down is much better than the original one 
which allowed the plastic lock to slip thus creating many display 
problems. The screw to attach the right clutch to the screen is a little 
bit short in my opinion. It is the same length as the old one, but should 
be a few millimeters longer to account for the increase in metal 
thickness on the replacement clutch. As soon as I get the time I will 
take some pictures of the parts and send them to whomever would like them.

Whilst taking my aero apart, I also managed to disassemble the (B/W) display:
After having removed the upper half of the aero, unplug the display cable
from the mainboard and remove the lower of the two screws in the back of
your aero that kept the display in place. Now you can take of the whole
display. To disassemble it, you have to remove the two small round plastic
plates in the lower left and right corner of the display to gain access to the
screws covered by them. Remove these screws and than CAREFULLY unsnapp the
upper half of the display casing (the one arround the screen). If I
remeber it correctly, there are three of these "snapp-in" things on the
lower edge, three on the left and right edges and about four on the
upper edge of the display. Again, you really have to be very careful when
doing this! The display itself is a single unit with a metal chassis - and
below it there is a small PCB containing the circuit to power the backlight.

From: Peter Barrette 

  If it isn't one thing, it's always another. Having recently replaced 
the infamous right clutch I had hoped to get more use out of my Aero. 
However I managed to drop the damn thing and break the backlight. The LCD 
screen itself is without damage

The backlight in the Aero 4/25 is a small flourescent tube approx. 143mm 
long and 3mm in diameter. It is called a CCFL which stands for Cold 
Cathode Flourescent Light. Mine also has the number 3121 printed on one 
end. I have yet to find a replacement since Compaq only offers the entire 
display assembly. I have, nonetheless, outlined the procedure.

If you know where I can get a replacement please let me know.

The Replacement Procedure:
  1. Remove the screen bezel (The FAQ has an excellent description).

  2. The backlight is located in the white plastic rectangle just to 
     the right of the LCD screen. 

  3. Using a small phillips screwdriver, remove the three screws in the  
     white plastic case. Lift the right edge of the plastic panel up and  
     pull to the right to remove it. You should now be able to see a 
     thin, white, plastic film gently folded over. 

  4. Upon unfolding it can be seen that the other side is reflective 
     (like mylar). You should also now be able to see a long, white tube 
     with a white wire coming off of each end. This is the backlight. 

  5. To remove it, you must unplug the wires from the Backlight inverter  
     (the small rectangular board at the base of the screen). 

  6. The wires are also held underneath a small, metal grounding tab 
     that is held down by the display clutch's top screw. 

  7. Remove the screw and the grounding tab and remove the CCFL tube.

Worn out letters on keyboard:
When I bought my Aero, I was disappointed that several of the letters
had completely worn off. I found they could be replaced with rub-on
lettering from an art supply store.

First, pick out your lettering. You get a sheet with many copies of each
letter, so you can practice a bit.

Then scrape off the fragments of the old worn-out letters. I found that
a bit of 800 grit sandpaper helped.

Rub the letter on the key. Be sure to press the key down first, or as it
shifts under your rubbing, the letter will break up. If you don't like
the position of the letter, it is easy to scrape off.

Then you need to put on a protective coating. Clear fingernail polish
may work, but I've used it for other things and have found that it's too
hard -- it chips off. I happened to have a $3 bottle of Clear Coat
touch-up, which I had gotten at Trak Auto for my car. It worked well,
and so far shows no sign of coming off.

Since I had the Clear Coat out, I coated a couple of the original
letters that were showing wear. I am hoping to go to a larger Art Supply
store to try to find some smaller, blue-colored letters to match the
other parts of the keyboard.

This occured on all models of the Aero. New units are now shipping with the new

The problem was one of being too slick. The ball was polished and shiny. Any
oil, dirt, fluff, etc. that would get under the trackball would cause it to not
work properly. Compaq came out with a "roughed up" version that fixes the
problem. Call Compaq at 1 (800) 841-2761. I believe that this is the only 800
number to call. If you are outside the US, call your local distributor, or call
Compaq directly. They will send you, free, a trackball cleaning kit and a
high-friction replacement trackball. All you have to supply is a serial number
and a shipping address.

or you can sand it down:

I don't recall whose brilliant idea it was to sand down his track ball to

From: Matt 
Subject: Trackball problems/resolutions

I just performed surgery on my Aero again this evening. My trackball was
not working very well, so I decided to open it up and see if I could fix
it. The trackball worked fine left and right, but did not work very well
up and down. (Note: I'm using the original ball, but roughed up with
sandpaper as per the FAQ) Anyway, I removed the trackball assembly from
the case and discovered that by removing two screws from the bottom of the
circuit board, I could remove the top half of the trackball assembly. What
I found inside was pretty interesting.

The top of the trackball assembly contains the "bowl" for holding the
trackball and the rollers. The rollers are on a small metal shaft that
fits into a slot in the side of the assembly. The roller is actually on
the far end of the shaft. On the other end of the shaft is wheel with
teeth similar to a gear. A spring touches the shaft in the middle, halfway
between the "gear" and the roller. It is this spring which holds the shaft
in the slot in the side of the assembly. 

Affixed to the circuit board are two housings that contain an LED and a
photocell. In each housing, the LED faces the photocell. When the upper
trackball housing is fitted to the circuit board, the two "gears" slide
into a slot between the LED and the photocell. 

I discovered that a bunch of fibers had accumulated on the roller shaft
and had also wrapped themselves around the retention spring. I figure that
as the shaft turned, the fibers pulled on the spring, increasing friction
and making it harder to turn the shaft. Cleaning these fibers off the
shaft produced a noticeable improvement in trackball performance. Up and
down movement works perfectly now. If you've been having a similar problem
and are brave enough to open up your Aero (or you have your Aero open for
any other reason) check out the trackball assembly. 

(One bit of warning: There is a small pin and spring that makes an
electrical connection between the circuit board and the trackball
retention ring. I'm not sure what it does, but the spring is easy to loose
when you open things up. --Matt

[C] From: GStew 
Date: Tue, 27 Jan 1998 23:07:27 EST

1. Clean the rollers with Q-tips soaked in rubbing alcohol.
2. Use a pin to carefully remove any lint and hair wrapped around the roller
   axle wires.
3. Use a pin to carefully position the rollers equidistant on the axle wires.
4. If the trackball is smooth and shiny, rough it up with 220 or so grit

This should get it moving freely again. Then, keep a small spray bottle of
rubbing alcohol around to spray the ball when it sticks... that'll get it
going again for awhile... but eventually, you have to clean it again.

[Q] What can I do when my trackball is not responding?

[A] First make sure you do not still have the original smooth trackball. This
is a known and very common problem. Replace it with the new matte-finish ball
from Compaq or sand it slightly (see above).

In order to clean the trackball you suspend the machine (turning off is
probably better), twist the locking ring to the left, remove it, tip the unit
'til the ball falls out, and then clean rollers and such with a lint-free cloth
and at least 70% isopropyl alcohol. Camera lens paper is good for this, or use
SPONGE-tipped swabs. Cotten-tip swaps such as Q-tips can leave fibers in there
which will mess things up.

[A] Sounds like a case of the classic dirty trackball. Use the "Compaq Learning
Center" and read how to get it out and clean it. One of the rollers is slipping
which makes it look like one dimension is fixed. It happened to me all the time
until I got the new trackball from Compaq. Now it just happens maybe once every
other week and I just wipe around inside the trackball hole for a few seconds
using my shirt tail and pencil.


Subject: Ballistic Mouse driver?

[Q] Does anyone have drivers/programs which give you "ballistic" mouse
response? The Microsoft Ballpoint Mouse driver has this sort of feature. The
faster you move the trackball, the more distance is covered by every mouse
tick. If you move the mouse very slowly, it might take several revolutions to
get to the other side of the screen. Move it quickly, and you're over with a
flick of your thumb.

[A] The file I've got is -- a new version of the Logitech mouse
driver which vastly improves on the one bundled with the Aero.


Subject: Trackball and left-handedness?

I'm left handed and I like the trackball. Some of the Aero reviewers have
treated left-handedness as a disability. Left handers grow up in a right-handed
world. The Aero trackball is no big deal to worry about.

From: miker
Subject:  Battery charge circuits

... But here's how I think the thing works. There's a chip that manages
the battery. It swithes a FET in series with the battery negative.
The load is placed directly across the battery & fet. The AC adapter goes
thru an isolating diode and is also placed directly across the battery and
There'e a green light on the front panel that shows that the battery is
charging. (ignore the flashing modes for now) The fet is normally turned
on. The only time the fet turns off and disconnects the battery is when AC
is applied AND the green light is off.

When you plug in the AC power, it is connected directly across the battery
thru the turned-on FET. (That's why it's very important to use ONLY the
supplied AC adapter. One without the correct current limit will cook your
battery and maybe destroy the computer.) 

The battery charges until the proper voltage conditions apply OR the
temperature increases to the point that the thermistor decides to turn off
the charging. At that point, the green light turns off and the FET turns
off disconnecting the battery. According to the schematics, there is no
trickle charge current. It should be safe to leave the AC adapter plugged
in continuously. The downside is that if you do it for a long time, the
battery will discharge itself and not be ready when you need it. You can
reset the charge circuit by removing the battery for a few seconds with AC
disconnected. I've not discovered all the details of resetting the charge.

Another point is that the signal that controls the green light is not the
same wire that controls the FET. I blew mine up thru a battery mishap.
After I replaced the fet, the green light would go off indicating
full charge,
but the signal to turn off the fet was broken. The battery continued to
charge and get very hot. Luckily, it's possible to synthesize the required
fet control signal from existing signals from the chip. 

FnF8 should tell you whether the machine thinks the adapter is plugged in.
Under normal conditions, 'bout the only difference is that the disk will
refuse to spin down with AC applied. There are additional power control
functions supplied by the operating system. Those seem to conflict with
the hardware power settings. I've only been able to get WIN95 to put the
machine to sleep by turning off the hardware power functions. 

So, If you can plug in the AC and the green light comes on then goes off
later, the battery is being charged and the computer understands that AC
is connected. If the battery continues to get VERY hot, you may have a bad
charging circuit. With the machine turned on, check for voltage at the
center conductor of the power socket. If there is, you may have a shorted
series diode. That would affect whether the computer thinks AC is present. 

Bad batteries can cause all sorts of strange symptoms. That would be my
first choice of something to replace.  miker

Subject: Replacing the Battery

[C] Date: Fri, 22 Jan 1999 17:08:05 -0800

New Topic/horror story: New Cells in the Battery.

Sometimes, it's worth looking stoopid to help others avoid a mistake.
This is one of those times.

You can take the battery apart and put in new cells...if you can find the
cells. I found some New Old Stock Cellphone batteries with the correct
cells, so I've been putting them into Aero packs.  I've done this
successfully a few times and got careless. So, I stuck in the cells and
glued it back together. I carefully checked the battery voltage and
polarity. I checked that the thermistor was still hooked up.
I shoved it into the Aero and pushed the purple button.
Nothing happened. I was scratching my head when clouds of smoke billowed
out of the machine. I removed the battery immediately and retired to the
kitchen for a beer and a good cry. I had another beer, more tears and
started kicking myself.  After sobering up, I took it apart.

Here's what happened. The thermistor contact on the battery  adjacent to
the positive terminal is connected directly to ground inside the Aero.
There's a small piece of "fish paper" inside the battery that insulates
the contacts.  If this gets mis-adjusted, it is possible for the two
adjacent contacts to short. Even if it isn't shorted outside the
computer, the spring force holding it in could cause the plastic
to shift enough to short when you install the battery.
When you stick it in the computer, the battery gets connected directly
across the charge-control FET.  The result is that the FET vaporizes and
takes a chunk of the circuit board with it.

Fortunately, I had an extra dead motherboard that I could steal the fet
from.  The board wasn't as bad off as it looked.  Doesn't look like
anything else was hurt.

So, if you put new cells in your pack, watch the position of the
insulator and push hard on the plastic while you check for shorts between
the thermistor terminal and the battery terminals.

To answer your question regarding battery compatibility, you are correct
in guessing that the Armada 1100 series shares batteries with the Aero.
Also sharing the same battery is the Contura 400 series.  So, when it is
necessary to call the retailers for a new battery, be sure to ask for all
three applications.

It's not likely. The Li-Ion chemistry requires a very different charging
technology, namely the charger has to have the ability to sense various
factors in the battery and adjust charging voltage and current accordingly.
It should be possible to charge a Li-Ion battery separately in a smart
charger then run it in a plain laptop, however. Definitely a serious
project to do the conversion.

No, you can't use Lithium units in Aero... Besides, there's not one

the default used on Aero / Contura / Armada 1100 series.

I just finished taking my old 3 hour battery apart.  It has 9 rechargable

so can be used with another set of batteries.

The batteries are:

Size 4/5A rechargable nickel metal hydride

These batteries are slightly larger in diameter than standard AA

The standard battery is approximately 140mm long.  The enhanced

Hello Dada,

Here's my *weighted* opinion regarding Conditioners for batteries...
First, some background...I have an Aero 4/33c which I've owned since
1994.  Early this year , I started looking for a new battery since my
original batteries were very tired, and virtually useless...I happened to
find an Xtend Hypercharger/Conditioner for sale and decided to try it.  Boy, wa
s I happy.   I
"revived" one battery to 1+hour capability, and the other to only 30
minutes.  Not perfect, by any means, but still worthwhile.  It started me
thinking that others were having similar dilemmas, and that many of us
were *shocked* by the prospects of shelling out $100+ for a new NiMh
battery for our aging Aeros.  This put me on the search for less expensive
options, and ultimately led me into re-selling specific Aero items which I
thought others would also need.The bottom line is this...CONDITIONING in
itself is very important for NiMh batteries.

I have seen various "opinions" regarding how best to accomplish and
maintain proper conditioning and battery care, whether simply by being
sure to FULLY DISCHARGE the battery every time you use the laptop, and
allowing to FULLY RECHARGE uninterrupted in your Aero, or by using an
external Hypercharger/Conditioner  such as the Xtend units

I have been reselling.  The simple fact remains that proper battery care
is perhaps the most overlooked aspect of Laptop maintenance, and perhaps
the most costly in terms of performance of the laptop and  high 
replacement costs of the batteries.  A good source of battery care
information(IMO) can be found at the Xtend site here:

I can only speak from my experiences, and state that I have been amazed at
what these Conditioners can do for batteries that people have considered
"DEAD".  I now am handling IBM products, and have rejuvenated many
batteries which were considered JUNK, and brought back to useful life via
the Conditioning cycle in one of these Xtend units.

Sorry for the long discourse....I'm sure others will elaborate and/or
correct  :)  my statements and give you a wider spectrum of opinions on
this issue...

Have a Great Day,

[Q] I have an Aero 4/25 with only the small battery. I purchased it used from a
friend, tho he had only a few months on it (wanted money for a car). When I
bought it, the battery would charge up to a reading of 165 or so, while now it
only goes to 157. Being Ni-MH, it shouldn't (as far as I know) suffer from
memory problems as a NiCd would. Any comments?

[A] From what I've read, NiMH does suffer from the memory problem as do the
Litihium-ion batteries. It's just that they are not as suseptible to this
malady. It's still a good idea to condition the battery every now and then.

  --Ed. Note: Yes indeedy, the aero battery will develope a nasty memory
unless you discharge it down every now and again. However, do not discharge
it all the way to 0 volts or you CAN DO IRREVERSIBLE DAMAGE. Several 
methods have been tried to achieve this goal; everything from car 
headlamps and electric fans to power cycling the aero. The important thing
to remember is just letting the aero run till _power down_ does not seem to
be enough. You should condition your battery every 45 days or so. At the very
minimum let it discharge three times from full charge without hibernation.

I was speaking to somebody at a shop called "Batteries Plus" in Osborne
Park, WA Australia the other day about battery dischargers, and he said
that you have to be *VERY* careful about discharging the battery too
much..  He suggested that it should not be discharged below 1V per cell
in the battery pack - i.e. probably 8 volts on our Aeros, assuming there
are 8 cells in it (I think that'd be right).  I would tend to believe him
a) because he seemed to know his batteries pretty well; and b) when I was
getting 4+ hours out of a battery and accidentally left it on my 200mA
discharger overnight it only lasted 2 1/2 hours the next charge.  It's
okay now after 10 or 15 complete cycles, but it's something to keep in mind.

From: Steven Lawson 

This is really screwy, but until I build a discharger it's worked
for me:

  1) boot into DOS mode (F8, command prompt only)
  2) turn on drain mode with the popup function
  3) run looping virus checks or something that moves the heads
  4) wait till the Aero suspends
  5) pop out the battery, pop it in, go to #1

At some point the Aero will do it's 'low battery' beep during the
bootup.  At this point, step #4 will never happen.  Instead, the
Aero will *EVENTUALLY* shut itself off (no, not a nasty low
voltage crash, power management clicks it off intentionally)

Believe it or not, once I got to this point my Aero ran for another
30 minutes before turning off!  I did this a couple of times and
my battery life appears to be back to where it used to be when
it was new...  Step #3 is just to make the system discharge
faster - I can't imagine what that 30 minutes would have been
without the heads seeking around.

so I can't recommend it.  If you try it and YOUR Aero explodes

Subject: Batteries discharging too quickly when suspended

[Q] There was a discussion about problems with batteries running out of charge
too quickly. I wonder whether mine could be the same: When I use my Aero with
batteries I can work ca 2-3 hours as usual. But when I suspend a fully charged
machine and resume it after, say, 30 hours nothing happens. It has run out of
charge! I have read that the Aero should be able to stay suspended for weeks.
What's wrong?

[A] Do you have anything set so that the PCMCIA or parallel/serial ports remain
powered when in standby? I know you can do this on the PCMCIA port, and 30 hrs
sounds about right for a PCMCIA modem draining the battery.

[A] I would expect the standby to die after 30 hours. I have set my Aero to
"stdby to hibernate mode". It works OK most of the time, but sometimes when I
restart, my mouse is WHACKO! For now my favorite is just to "FN+Purple Button",
and reboot every time which is 100% reliable. I prefer a cold boot before every
session. It is worth the 42 second wait. Besides I can use that 42 seconds to
lean back and stretch or scratch or something.

[Q] How do I change the settings so that the power to the pcmcia port is shut
off on standby? I couldn't find it using the power management utility.

[A] It's under PowerManagement&Hibernation->PCMCIA -- there's a checkbox
labelled "Leave Card On During Standby". I believe you have to have a card in
the PCMCIA slot in order to get this option listed. It's also the same window
that is displayed when you insert a card (if you have "Display Message When A
Card Is Inserted" turned on) -- to get to the display message checkbox, go to
the PCMCIA page as above and select the OPTIONS button.


Subject: Super-fast recharge? Charge indicators?

[Q] My battery seems to recharge in about fifteen minutes. That's not with the
machine running, and not from absolutely zero (as in "left on over the
weekend"), but it is from 0 marks to 5 on the battery check icon. Which brings
up some questions:

Is my battery recharging too fast? Are NiMH cells damaged by rapid recharging?
How much do those battery check marks mean, anyway? Mine seems to go
"5554444444444444442222222222222111000". I don't think I've ever seen three
marks displayed. I assume they represent a voltage measurement. Is there a way
to get higher resolution indications, or technical data on the existing one?
How much computing should I expect after I see zero marks?


Subject: Battery Monitoring

[Q] The Aero provides low-level support for querying the battery status, so any
program that advertises "APM compliance" should run on the Aero. It's fairly
simple to fetch it, so it would be strange if nobody has written such a

[A] The PowerMonitor does this job very well on my Aero. You can find it as on CICA or it's mirrors in the desktop-directory, I think.


Subject: Battery Loose?

[Q] I have the aero plugged into the wall, and yet the aero doesn't think so
(the little light isn't on). I thought I recalled someone saying something
about the battery, so I took it out and sort of wiped it off. This worked.

[A] This doesn't seem right, since the battery should be parallel with the
external power. I can take the battery out when the external power is plugged
in, and it continues to work.

[A] Contact Compaq. You can't do anything to fix this problem on your end. I
had this problem. I complained to Compaq. They sent me another unit.


Subject: Please explain the aero battery

[Q] I am completely confused about the battery situation. Are there different
batteries, an extended and a normal? Is the extended battery a different
size/weight? Which of the batteries is this new standard size Duracell? Which
battery comes standard?

[A] They are BOTH duracell batteries, long and oval, with an indentation
running up one side. The mono (my mono 4/25 84 meg drive) came with the short
one, which only fits because of a plastic spacer. The compartment is 2" longer
than the battery. The extended battery fills the whole compartment.

[A] The color Aero 4/33c comes with the extended. The extended fits in the
monochrome Aero 4/25 though.

[C] Runtime estimates are variable, but it is a whole new world compared with
my Epson luggable. If you keep the light low, and don't use the disk much, you
can get 5-7 hours of continuous use with the extended battery. In practice,
though, you tend to get distracted, do something else. Then the Aero goes to
sleep. I used it on an all-day train trip without swapping batteries. 10 hours
of this sort of use is standard. I usually use the longer battery. The shorter
one lasts about 2/3 as long.

[A] The PCMag tests were pretty low usage; look at the sidebar regarding how
they did the tests. I wouldn't expect that long a life in real-world use. I
normally run my Aero 4/33c (with 12 meg memory) at "medium" battery
conservation, two to three hours at a time running AmiPro. The hard drive
seldom spins down and the display is on during (~100% brightness) the entire
time. I normally have around 2 of the five blocks still filled in on the
battery "status", or supposedly around 40% of the charge left. I haven't yet
managed to fully drain the battery through actual use (only by intentionally
turning off all battery conservation and letting it sit). Unfortunately, I also
haven't had the opportunity to time the length of time it takes to drain a full


Subject: Recharging in the auto

It is possible to plug in the aero directly to a car's internal 12V

The power brick that comes with the aero can plug directly into a 220 V

Those bricks do pass EM radiation specs. If they pass TUV,
they are good units. However, the testing and specification
for near-field versus far-field is very different. 

The near field (the magnetic field from the transformer,) is what's
screwing up the floppy drive. It's also very hard to shield. (In the 
old days, you could easily screw up a 9-track tape just by laying
it down on the back of the case of a CDC or AMPEX 80mbyte drive
that was seeking a lot.)

Oh well, first we learn not to stick floppy disks to our fridge using
refrigerator magnets, and then....

I take strong exception with this advice.
The Aero has a FET in series with the battery.  It turns on hard during
charging. When it's fully charged, the FET turns off completely.
So, while it's charging, the external power supply is connected directly
across the battery.  The current limit in the power brick reduces the
voltage to that of the battery and determines the charging current.

If you use ANY power brick other than the one supplied, you will get
the wrong current.  If it's just a little too much, you'll merely
overcharge the battery. If it's a little more too much, you'll explode
the battery eventually. If it's a lot too much, the FET will come out of
saturation and melt. See more on this below.

There are also problems with the power bricks,  They don't like to be
overloaded. In fact, many don't have any overload protection at all.  The
internal resistance of the transformer limits the current somewhat, but
causes overheating until the internal protection, fuse, thermal switch,
etc cuts out.  The rating printed on the brick has to do with UL and
safety laws.  You can NOT count on it to represent anything other than
the maximum RATED current of the supply.  RATED and ACTUAL are often NOT
the same.  If you stay within the ratings, the supply is not supposed to
catch fire.  If you exceed the ratings, the power supply is not
supposed to catch fire.  There is no guarantee that the load won't catch
fire.  The AERO is NOT a standard resistive load.

Many bricks with switching regulators have foldback current limit.  When
you stick this across a battery, you may get bizarre behavior.  Your hard
drive may be sorry this happened.

There are a lot of ways to design battery/charger systems.  The AERO 
system is particularly light weight, low cost and efficient, but it
depends completely on the characteristics of the AC power brick.

On a related thread, people have reported success connecting their aero
directly to a car battery. They have been lucky.  There's almost no
protection inside the aero for overvoltage spikes normally
found in an auto electrical system.  The internal battery will provide
some limiting while it's (over)charging, but as soon as the FET cuts off,
there ain't nothing to stop your starter spikes from trashing your
computer. The only reason this works at all is that the car battery
voltage with the engine off is low enough that you don't immediately
smoke the internal battery.  Running at 14.4V with the engine on is
definitely too much. Don't do it. MUCH MUCH safer to use a 12V to 110V
converter and the AC supply for the AERO.

As you might know, I have the parallel port version of Iomega's Zip
Drive and tried to get fast EPP transfers with my Aero.

I don't have much hopes anymore of getting it to work.

The facts as far as I know them are:

1) There exist two slightly different EPP standards:
   a) 'old style' EPP aka EPP 1.7
   b) IEEE 1284 EPP 1.9

   For further details you might have a look at the manual of the
   "parallel.exe" utility
   <URL: >
   or see
   <URL: >.

2) Our Aero has an IEEE 1284 EPP 1.9 style parallel port.

   Compaq Technical Support answered me:
   | Correct Compaq used EPP 1.9 for the LPT port of the Aero.  Compaq
   | does not offer a special driver to convert this backwards to 1.7,
   | sorry.

3) The Zip Drive software (and hardware?) only supports EPP 1.7.

   I called Iomega's European hot-line and they seem to be quite
   competent.  Unfortunately they told me, that it's actually EPP 1.7
   only.  And there won't be any futher development (at least for Win
   3.1, that's what I asked for).

   And Iomega European Technical Support, Ireland, answered me by
   | Ihre Nachforschungen stimmen. Es funktioniert nicht mit EPP 1.9.
   | Wir senden keine Source-Codes aus.
    (Your investigations are right. It doesn't work with EPP 1.9.
     We don't send source codes.)

   BTW, beside the ASPIPPM1.SYS driver (with *.ILM files) there also
   exists an ASPIPPM2.SYS driver (with *2.ILM files), but I tested
   all of them and it doesn't help either.

==> Conclusion: we're stuck with byte or nibble mode.

Subject: Mouse on serial port

[Q] Problem One: I got a serial mouse to work in DOS no problem with the driver
that they supplied. However, the windows environment defaulted to the
trackball. So I used setup to modify it for use with a logitec mouse (what I
have) but then I lost the ability to return usage to the compaq trackball and
its nifty driver. I had to restore the setup using my tape backup. Is there an
easy way to switch back and forth between serial and trackball?

[A] This is what I did: in the mouse subdirectory in the file mousedrv.ini you
need to change two entries in the [Global] section:

SearchOrder=Serial, PS2, Bus, Inport

(Read the file mousedrv.txt to understand what you are doing.) This will cause
the mouse driver to search for a mouse on the serial ports first before looking
for the trackball. Reboot the machine, whenever you attach or remove a mouse.
It works fine with my el-cheapo mouse when it is set to emulate a Microsoft
mouse. Automatic recognition does not appear to work with the PC-Mouse

A normal serial mouse can not be used on the PS/2 mouse port. Even the
available "serial-to-PS/2" adapters do not help. The signals and the
protocol is too different. Only a PS/2 mouse does work on a PS/2 port. By
the way there are some kind of "combined-mice" just as Microsofts
"Serial/Mouse Port Compatible Mouse 2.0" (Nr. 58264) and Logitechs MouseMan
M-CJ13 and TrackMan T-CC2-9F. The owner of such a Logitech-mouse can use a

You'll have to open up your Aero - the battery is about the size and shape
of a dime, located (as I recall) almost dead center on the system board.
You can use an x-acto knife/small screwdriver/paper clip to pop it out.

Also, shorting across the contacts once the battery is removed is how you
clear the CMOS on the unit.

(I guess my suggestion of using an x-acto knife/small screwdriver/paper
clip to remove it doesn't inspire confidence eh?)

Date: Thu, 19 Apr 2001 09:21:45 +0100


Having had a dead Aero for 6 months now with the old "101-ROM ERROR" I
decided to do something about it.

Trawling through the FAQ's and newsgroups I read that usually the BIOS
contents are ok when it gives the "101-ROM ERROR", but just cannot be read

So, dismantling the laptop and hooking up the PCMCIA floppy with an earlier
created BIOS flash disk, I froze the BIOS in situ with freeze spray. The
machine then got past the POST stage and booted off the floppy and ran
through the flash routine successfully. This re-flashed the BIOS to SP1992.
The results are that the laptop is now back to normal.

Though I would share that with all you Aero owners.

Rom error 101 again.

It gets more interesting. My Aero died again with rom error 101.
I forgot an tried to start it on AC with a VERY dead battery. That seems
to have been the common thread in all my rom error 101 problems.

So, I pulled out the bios rom to reflash it. Just for fun I checked the
contents first. The programmer sez the data matches the file. My heart
sank as I imagined a tiny tombstone atop my deceased Aero.

I didn't have a better idea, so I erased and reflashed the BIOS ROM.  Aero
is back to life.

So, it may have something to do with the speed the rom is accessed.

I don't have a conclusion.  Just thought I'd put it out there
in case it might help someone else.

Subject: Trashed my BIOS again.
Date: Thu, 03 Aug 2000 02:31:32 -0700

The BIOS on my 4/33C died again.  Second time on this one and fourth 
one I've fixed. Symptom is that it finishes memory test then either 
gives an i/o error or just locks up.

I have a theory on how to prevent it happening. The trashing
seems to happen on power up after the machine has been sitting.
Here's what I think happens.

The battery discharges when it sits.  The charger doesn't reset.
It still thinks the battery is charged.  When you turn it on,
the voltage is too low.  The AC adapter current limits and the
voltage is still too low.  This starves the internal regulator
and lets the voltage wag around.  There's a squealing noise and
the display backlight takes a long time to come on. There's no
pulldown on the flash programming pin.  Maybe this gets glitched
trashing the bios.

Anyway, to prevent this condition, do the following: If the
machine has been off for days on end, attach the AC supply. If
the charge light comes on, wait till it goes off.  If it doesn't
come on, pop out the battery for a few seconds.  Putting it back
in should light the charge light.  Wait till it goes off. I've
also gotten into the habit of measuring the battery voltage 
before I turn it on.  I have seen shorted cells that could do
the same thing.

If you use it regularly, this shouldn't happen anyway.

Maybe this can keep more aeros on the road...

I've had to more than once do this:
The following is CONJECTURE.  Use at  your own risk.
The ROM seems to lose it's brains over time.  They saved a penny
by leaving the pulldown resistor off the program line.
It's possible that a glitch can cause the chip to go momentarily
into program mode. Or it may just be a leaky bit in the rom that
causes it to lose it's charge. I've fixed several by pulling the ROM and
reburning it externally.

You MIGHT be able to fix it by installing the flash BIOS update.
I think it's sp1992.  There are a couple of issues with this.
If you've already got 1992, it might just refuse to install.  Don't know.
Also, if it flakes out while it's burning it will hoze itself.
Then you won't have a copy of the data.

When I did mine, I pulled the ROM and stuck it in a ROM burner.
Then I sprayed it with freon to make it really cold while I read it.
Then I just burned the data back in.  Worked great.  If your ROM
is more seriously damaged, you'll need a new blank ROM.  They're
inexepnsive; but the only places I found them wanted to sell me a whole
tube of 30. If you can't get a good read, you'll also need the data.
What's on the rompaq floppy does not appear to be a useful form of the bits.

Of course, it may be that your problem is completely different.

All the AEROs I've ever seen (4) all had socketed system roms. They can be
reprogrammed with most any prom programmer, but you have to buy or build
the adapter to get them to plug-in. You need the code, but that can ba had
from a working system. Not at all clear that you can get the code from the
rompaq files. Looks like they encode it.

I've fixed three AEROs by reprogramming the system ROM. They didn't put a
pull-down resistor on the programming line. If the line gets glitched
during power down, etc, there can be a cumulative effect on the flash rom.
Or maybe it just loses a bit over time.

Suggest you pull the flash ROM and try reprogramming it. 

Also, I once bought a used "cheap" system board. It had a bad rom in
addition to other problems. Think this might be a common AERO problem.

There is also a virus that reprograms the flash bios of some systems. I've
never been able to document a case that could be traced to a virus. But as
a precaution in any system with a bad ROM, I'd suggest pulling the hard
drive, putting it into a non-flashable bios system and runninc
cleancih.exe on it. There may be others by now.

As you receive the error

According to Compaq, "Beyond Setup" manual, Appendix B, page

FDD drivers are built into the BIOS. You can boot from it with nothing on the

Subject: Connecting with out powering down

[Q] The docs (skimpy, as I mentioned), suggest that I should be able to connect
the floppy w/o powering the system down: go to standby, plug the floppy in,
back out of standby. When we do this, and, say, go to filemgr, MSW says the
floppy in unformatted. If we power down, plug in the floppy, then reboot, all
is ok.

[A] That is normal. If you machine keeps power during suspend drivers will
remain. But if you pull out the connector they will dissappear and connector
card must be reinitialized.

[A] Strange, you should be able to hot-swap your floppy (i.e. plug in and
out while the computer is on and not suspended). The aero will notify you
of this fact when you perform this operation. This is a perfectly
acceptable thing to do, infact that is what the PCMCIA slot was designed
to do. This may require an updated BIOS and/or PCMCIA drivers.  - Philip


Subject: Aero does not recognize floppy drive

[Q] I have recently purchased the COMPAQ PCMCIA disk drive. My problem is that
I cannot get the Aero to properly recognize the drive. If the drive is plugged
in when I boot the computer, I can use the drive fine. The PCMCIA configuration
window in Windows, however, will report that the card is "not configured." If I
try to plug the drive in after the computer is already booted, it will not let
me use the drive at all. I have the latest SOFTPAQ (version 1.45, rev. A) and
PCMCIA drivers (version 1.25, rev. A). Also, my X-Jack modem seems to operate
fine in the PCMCIA slot. Any suggestions on how to get the floppy up and
running? Any help would be greatly appreciated!

[A] If you are using MS-DOS or Windows 3.1x, the easiest way to fix the
problem is to get the very original CONFIG.SYS of Aero which is well
configured to work with the drive.
     Note: see FAQ sections on the config.sys file

[A] Try removing some of your third party software (non-Compaq stuff). 
Sometimes these packages futz with the floppy drive, like for instance
Colorado Backup.

[A] Look in the sections of the FAQ on specific operating systems for more
detailed information on this, and related floppy woes.


Subject: Problems reading/formatting disks

[Q] A floppy will work fine, then all of a sudden I get missing sector (not bad
sector) errors, and I take the floppy out and put it back in and I can't even
FORMAT the thing. It was a brand new floppy, BTW.

[A] I recently ran into the same problem, 2 disk in a row. It was some
inexpensive, unbranded diskettes. My symptoms were nearly identical to yours,
including the inability to reformat the disks on the Aero, however, I could
reformat them on each an every (other) computer I tried!

[A] I've found that this problem tends to appear when you have smartdrive
running and fail to include "a-" in the command line. Even when drives
supposedly support floppy change detection, I've just never had good luck with
smartdrive & floppies. (By default, it read-caches them.) Try running "smartdrv
a-" and see what happens.

[A] I'll second at least some of this floppy trouble. When running dos or
windows I had a heck of a time getting floppys formatted. I finally got to the
point where I'd never bother trying to format disks on my Aero but use some
other machine. After getting them formatted (elsewhere) I had no troubles with
the disks. I haven't had this problem since I switched to Linux.

[A] I haven't had any trouble, and I have formatted about 30 disks of about 3
different varieties. Maybe there is a change in floppy supplier or model
somewhere, or maybe I've just been lucky.


Subject: Do you need a floppy?

[Q] For people that say "I dont want to spend the $99 for the floppy"?

[A] Try making friends with a local Compaq dealer. The floppy drive is really
worth the extra money, but if you bought your Aero after Compaq announced
that they were going to bundle the floppy WITH the Aero on Nov 1, and call
COMPAQ and ask real nice you may get a free one shipped to you like I did.

[A] Well, I am still holding out without a floppy. You can install Linux on the
Aero without floppy (which I did, but 4 MB is too akward for X), or the ROMpaqs
(which I have not yet tried). Better spend that money on an Ethernet adapter...


Subject: You still do not think you need a floppy?

The following story illustrates how you may end up needing a floppy, even if
you think you won't need one in the first place.

I decided to run my machine until the battery gave out if for no other reason
than to see how long it would last. In order to prevent damage to the
filesystems, I did a: smartdrv c- And then loaded dblspace and told it to
unmount my compressed drive which contains, among other things, my \UTILS and
\DOS directories. What I didn't know was that dblspace saves the fact that I
unmounted the disk to dblspace.ini on drive C:. This file is read-only, hidden,
system. This means that without changing attributes, I can't remove or change
it. I can't change attributes (or run dblspace) because the .ini file is
telling dblspace.bin not to auto-mount drive D:. I can't mount D: manually,
because it contains my DBLSPACE.EXE. (Yes, I feel like a fool.) I even tried
using Compaq's configuration utilities to overwrite dblspace.ini, but compaq
was nice enough to make it so it won't overwrite read-only files. I can't
figure out a way to force setup to let me go to a dos prompt, and I can't find
a way to force dblspace.bin to mount drive D:. It seems I need a floppy drive
to boot from so I can run a copy of dblspace.exe, remount my D: drive, and
(this time) copy the most important of my system files over to my uncompressed
drive. Would anyone be willing to let me use a floppy drive for a few minutes,
or is this something an authorized compaq service center would have?

Subject: Fixing an Aero floppy

I posted about a week ago a problem I had with a dead Aero floppy and no hard 
disk boot partition. I managed to fix the problem as follows:
I had figured that the problem was out of alignment floppy heads - cleaning 
didn't help. Still got disk I/O error when booted with floppy in. I plugged 
the Aero floppy into an Armada PCMCIA slot in the hope that I could create an 
out of alignment boot floppy, tried everything but could properly disable the 
Armada built in floppy so had to give up.
I took apart the Aero floppy and thought the floppy drive itself looked fairly 
generic although power was through the edge connector - not a seperate 
connector as in desktops. I then dug out the floppy from an Old Tosh3200 in 
the junk pile. This had a different edge connector and the floppy drive itself 
was quite a lot bigger but the edge connector was 26 pins and was 3.5 1.44mb.
I worked out the connectors and lashed up an adapter (26 small pieces of 
tinned copper wire !) to join the lead from the aero PCMCIA card to the Tosh 
floppy.  Unbelievably it works perfectly. I was able to boot using a
standard DOS 6.22 floppy and so could reformat and Fdisk the drive !

Subject: Fixing an Aero floppy - detail !

A couple of you have asked for more detail - here goes:

Take floppy case apart, you will see the lead from the pcmcia card is 
terminated by a flexible edge connector that plugs into the floppy drive  with 
a row of 26 pins. You can see pin 1 identified on the edge connector and 
circuit board of the floppy as J1. Remove this VERY carefully, If you bend it 
it will probably break. The engineering is excellent but fragile and light 
(like the rest of the Aero !)

For a donor floppy I used one out of an old Tosh but any floppy from a 
notebook - or even some desktops - should work. The key point is it has to be 
the sort that don't have a seperate power connector. I've never seen them sold 
new and the only desktops I've seen them in are Apricots (usefull for us 

The floppys will all be different but they will have some sort of 26 pin 
connector, normally 2 rows of 13 pins, You need to work out the pin order by 
looking at the edge connector to see if the order is 1-2-3 or 1-3-5 etc.

I then plugged a scrap connector into the new floppy that gave me 26 seperate 
cables that were part of a ribbon cable. I stripped the other end of these so 
that they had about 3 mm showing. Luckily the spacing was exactly the same as 
the edge connector of the aero floppy. I found the smallest soldering iron bit 
I could and tinned the 3mm of each cable. I then tinned the edge connector of 
the lead from the pcmcia card (sadly that means I would have great difficulty 
getting it to fit into an Aero floppy if ever I could find a replacement - but 
I was desperate !) I then carefully pressed each cable onto the edge connector 
with a soldering iron, just a touch was enough, obviously getting the 1-26 
order is critical as it includes a power feed as well as data - keep checking 
and re checking.

Everything then works fine. I booted the aero from a DOS disk (It felt like an 
eternity the first time I tried it and my nose was right by it sniffing for 
any burning smells !!!) I would guess the electronics and clever bits are in 
the pcmcia card as the Aero can't tell what I've been doing to its floppy. 

It doesn't get hot but I've been trying not to use the floppy too much as I 
would suspect it draws more power than the original - nightmare would be if it 
burns out the connector on the pcmcia card to motherboard, for that reason I 
won't dare try hot plug and play - which saves having to load one of the 
service packs !  Of course there is no case but I tended to leave the floppy 
at home anyway, I normally take a network connection and a short parallel 
cable to use someone elses PC when on the road.

Good luck if you try it and thanks to all those who made the FAQ so good, I am 
about to order a 2.1Gb Hitachi disk, now only 150 UKpds ($100) to fit into the 
aero. I might then have another go at putting Win98 on it - wouldn't fit on 
the current 250mb.

This turned out to be the key.  What had happened is that I installed the
CD-ROM drivers immediately when I installed W95.  It was only after that that
Windows installed the Compaq IDE driver.  The IDE driver had a yellow
excalamation point indicating a conflict, but I ignored that because the HD
worked fine.  The fix was to remove all the drivers associated with the
CD-ROM unit, then restart.  At that point there was no indication of a
conflict on the Compaq IDE icon.  Then, when I re-installed the CD-ROM
drivers, everything worked fine.

What this means is that, under W95 plug-and-pray, the order of installation
is significant.  There was a conflict when the CD-ROM driver was installed
before the IDE driver, but not the other way around.  This is
counter-intuitive, but true.

I sometimes have this problem.  And sometimes when the aero does recognize

Get one of those PCMCIA Y adapters that makes your 1 slot pcmcia
slot into two! I saw one on a PC110 - original type II slot used
to house a type 2 and 3 PCMCIA device.

I don't have one, but I've seen 'em in action.  They are about $50 and they
do work.  I'm not sure where you live, but in the Bay Area, I believe Fry's
Electronics (a discount electronic shop) has 'em.  They were being sold in
Japan for about $50 (prob. less expensive in the US).

[A] Yes and no... It will cause problems when your machine comes back out of
sleep mode with the mouse clicking on evrything in sight, but, if you comment
out with a ";" the line in Config.Sys that loads the PCMSMIX driver the problem
will go away. The V1.25 drivers do have an expanded card library so you can use
more cards without having to link their library in by listing it in the correct
place in one of the files in the C:\COMPAQ directory.

It was me who started the thread on this card. I've been using it for a
couple of months now; brief summary of experience follows:

(i) Windows 3.1. Only used it as a modem. The included communications
software was crap. Using other software it worked, but required the
extra initialisation strings listed in the manual, which was a hassle.

(ii) Linux. Ethernet, running TCP/IP and Appletalk has been a dream.
This is really what I use it for anyway, leaving the card at work to
hook my aero up to the LAN. I dial in as a dumb terminal from home,
where my 2400baud Intel modem still provides sterling service.
Haven't got the modem to work in Linux/Seyon. Even with the recommended
initialisation strings, I can get it to dial, but it chokes with "No
Carrier" before getting through. If anyone knows the answer to this I'd
be pleased to hear it. Something to do with the shared interrupt,

Overall-6/10 for the aero. Works, but hard to set up in some situations.

I just got an Angia SafeJack 19.2 PCMCIA FAX/modem and am having problems with
the Aero crashing (hard) when coming out of Suspend in Windows if I have it set
to turn off power to the PCMCIA card during Suspend.

After talking with Angia Tech Support, and Compaq Tech Support, I've found that

Subject: Ethernet Adapters

[Q] I'm very seriously considering purchasing a Compaq Aero for home and office
use, but there's two issues that still need to be resolved. First, I have to
hook the Aero up to a LAN at work, but need access to the network at home via
modem. Rather than buying separate PCMCIA cards, I'd like to get the combo
cards that Megahertz and Xircom both sell. Has anyone had any experience in
using either or both of these with the Aero?

[Q] I'm about ready to hook my aero/linux to my lan. The choices are PCMCIA and
using the parallel port. Linux seems to support several PCMCIA cards (I'm
leaning towards a LinkSys I saw advertised for $159) and the DE-600 port
adaptor. I know the parallel port will be slower (Ethernet HOWTO suggests
~80KB/S) but it might be more convenient if I want to use the floppy or modem
at about the same time (SLIP service perhaps). Is the EPP an issue (I've
gathered it's not 100% compatable)? Any thoughts? experiences? comments? war
stories? conquests? recommendations? warnings? (any more synonyms? :-))

[A] I'm using a LinkSys parallel port adapter on my 10base2 LAN at home. My
only complaint is that the network connection hangs if the Aero goes into sleep
mode. I chose this route over a PC Card (isn't that what they're calling PCMCIA
these days?) for maximum flexibility.

[A] I have been using the 3-Com 3c589 pcmcia with linux on an aero 4/33c. It
works great. I don't have any experience with the parallel port adapters,
however using a pcmcia net card under linux has some advantages. The pcmcia
card services package written by David Hinds, works GREAT. It provides most of
the functionality that the Compaq windows stuff had; hot swap, graphical tool,
automatic configuration including setting up the interface's address, netmask,
etc. (ifconfig), and tearing this down upon card removal. I seem to get good
throughput although I have not measured it. I would recommend the pcmcia.

[A] I've heard that Xircom will not release the programming details for their
cards, so you may want to stay away from them if this matters to you, or if you
ever wanted to run Linux on your Aero.

[A] Thanks to all who responded with their experiences with ethernet on the
Aero 4/33c under Linux. I am happy to report that I am now running Linux 1.2.1
and Don Hind's pcmcia package (v 2.5.5) with a Linksys ethercard and the compaq
14.4 modem cards and am very pleased with the results. I have X running and
picked up the latest beta version of netscape (1.1b) which runs remarkably well
over SLIP as well.

Recently I bought a product that has provided my Aero with CD-ROM and 
sound capabilities, all that trough the PCMCIA slot. It's name is CD
Traveler 2020S, by EXP ( I've collected the following
summary from their website:

"Now you can add a high performance twenty (20X) speed CD-ROM drive with 
built-in 16bit stereo sound to your notebook computer easily and 
affordably with the CD Traveler 2020S. You can access your CD software 
with blazing speed for data retrievals and searches when and wherever 
you need it. And you can also play your latest music CD's on this same 

This unit includes (20X) CD-ROM drive, PC Card interface cable and 
16-bit SoundNote module which have all been designed to work flawlessly 
together. And with CD Traveler 2020S, you will never need to bother 
carrying batteries or finding an AC outlet. Because CD Traveler 2020S is 
capable of drawing all of its necessary power from your notebook 
computer's battery."

From a users point of view, it works! It's great having a real sound 
Card in the Aero! The only downside was the installation, since the
manual's instructions are not up to date.

The following installation instructions worked on my Win 95 OSR 2, but I 
can not guarantee that it will work for you also, OK? For instance, our
floppy is also PCMCIA, right? So, what gives?

Solution: copy the entire contents of the installation disk to a hard 
disk folder. However, before going along with the physical installation, 
you should run (from the floppy drive)a batch file called "copy.bat", 
that you can find on the floppy's root. Then, turn off the Aero, remove
the floppy drive, and insert the "CD's and sound card" Card. Turn the
computer back on, and when the "new Hardware found" message appears,
direct the search path to the folder you created, and more precisely to
the Win 95 folder. All the necessary files/drivers should be there, and
all should go well. Restart the Aero, and after boot proceed to the
Device manager in the Control Panel. Locate a multifunction device, and
look into it's properties. Select update driver, and you'll be presented
with two alternatives: choose the one that adds sound to the CD-ROM
device. If needed, locate the sound driver in the folder you've created
earlier. Reboot again, and everything should work now.

So far my new device works flawlessly, but there are some things to 

1) The built-in speaker is mono; however, you are presented with a 
stereo output jack
2) You can use audio CDs; however, if you want CD sound trough the Sound 
Module, you should connect the two with a special cord ( supplied )
3) The DMA channel is provided by software emulation (windows); so, no DMA
channel available for DOS mode only applications.

Date: Sun, 18 Oct 1998 16:34:51 -0400

If you don't have the external floppy drive but you have a Zip drive, you
can use it as one. All you need is a $15 utility called ZppA. It allows you
to boot from a Zip disk. It's especially useful when you install SOFTPAQs or
if you want to install a new operating system, like Windows 95 OSR2.

This is an extract of

What is The ZppA?

The ZppA allows you to use your Iomega Parallel Port Zip Drive as if it 
were a high-capacity floppy drive.

It will even allow you to boot from a Zip disk!

The ZppA is installed in the Master Boot Record (MBR) of Drive C. It is 
loaded before the Operating System and will automatically detect a 
Parallel Port Zip drive that is connected. If a Zip drive is not 
connected, The ZppA will still be installed so that you can connect up a 
drive later.

The ZppA will then configure the Zip drive detected as either Drive A or 
Drive B.

If the Zip drive is configured as Drive A, you will be able to boot from 
it as if it were any normal diskette. We have even successfully 
installed full Windows 95 on a Zip disk configured as A: and boot from 

The ZppA will occupy between 4 to 5 KBytes of main memory when it is

[Q] Does anybody know if the bigger convenience base thing gives you any more
than the mobile port expander?

[A] In addition to the spot for recharging a second battery pack as mentioned

Mouse, Keyboard (PS/2 style), Serial, Parallel.

The serial and parallel connectors on the Convenience Base are pass-through
connectors. The S & P ports on the back of the Aero are passed through the
expansion port. This means that you could leave a printer and an external modem
(or other serial/parallel devices) attached to the convenience base. Just slide
the Aero into it you're all set -- it looks like it'd be a lot more convenient
than finding your printer cable and serial cable and plugging it in every time
you wanted to print or transfer files to/from your desktop machine. The base
comes with its own AC adapter. It will recharge a spare battery and the one in
the Aero (however, not simultaneously: it will charge the Aero battery fully
before it charges the spare).

The alternator is "buffered" by the relatively low impedance of the

to forget to unplug the computer before starting the engine.

Remember that auto electrical transients are huge and that computers
often depend on the "12V auto adapter" to protect them.

     is made by MicroCenter, because it has "WIN BOOK" on one side of the case.
     It is fairly small (smaller than most of Kensington cases). I can fit AERO
     (or a 6-lb notebook), AC adapter, mobile expander, floppy driver, and some
     cables in it. Two compartments. It is not as good looking/sturdy as
     Kensington's cases, but it costs only $20.00.

     Here is an idea for a cheap case for the Aero: A nylon covered, padded 3
     ring binder from Mead for $10. Line it with some 1/2" foam cut out for the
     Aero and it's power brick and floppy, and away you go.

Adaptec makes two adapters - a parallel port version and a PCMCIA version.
The parallel port version (APA-358 SlimSCSI EPP) costs about $155 and the
PCMCIA port version (APA-1460 SlimPCMCIA SCSI Card) costs about $170. I have
heard good things about Adaptec products, but they are not dirt cheap.

I am using a SCSI Zip drive with a Tekram DC-550P Parallel to SCSI 
adapter on my Aero.  I also have a MediaVision RENO 2x CD-ROM drive that 
I connect to my Aero through the same parallel to SCSI adapter.

The Tekram controller is brilliant - it has NT, OS/2 & DOS drivers (no 
linux drivers as far as I'm aware but I'm not using linux anymore); it 
supports EPP mode, and transfers *MUCH* faster than the Adaptec MiniSCSI 
Plus (which is admittedly not EPP, but is more expensive than the Tekram).

It is also significant to note that while the directory access speed 
between the MiniSCSI Plus & the CD-ROM drive is acceptable, when 
connecting the Zip drive to it, you can sit there for 10 seconds waiting 
for a "dir" to come up.  The Tekram has no problems at all, and the speed 
is quite acceptable (but I haven't managed to do any benchmarks).

Also note that the Adaptec controller *MUST* be supplied with termination 
power from the SCSI device.  I would guess that most portable SCSI 
devices do *NOT* do this.  My MediaVision RENO does; the Zip drive 
doesn't.  Most hard disks do.  If you go for an Adaptec, make sure 
beforehand that your device provides termination power to the SCSI bus, 
or it will not work, no matter how hard you try! (Unless you connect 
something else that provides termination power to the bus).

The Tekram on the other hand comes with two pass-through keyboard 
adaptors that will take power from your keyboard (9-pin mini-DIN or 
maxi-DIN) if your device does not provide termination power.  You could 
even connect an AC adapter into the plug if you didn't want to take it 
from the computer.  It works fine connecting the plug into the Aero's 
port expander.

The other thing that you'll have to note is that pretty much all Parallel 
to SCSI adapters that I've seen come with a Centronics *MALE* connector 
on them.  This means that if you want to connect to a Honda connector on 
the device, you must somehow get a centronics *FEMALE* to honda male 
adaptor (I have managed to get one, but it's not easy!!).  The best thing 
I've found with the Tekram is to buy a Centronics F-F gender bender 
(which wasn't that difficult), and then use a standard 25-pin male to 
50-pin centronics cable to connect to the Zip drive without a problem.

Hope this helps... if you have any further questions you can contact me 
directly (or through the mailing list if anybody else is interested...)

   You are right.  The setport utilities do not work.  No matter how you
set them, you will get a report saying that the aero hardware does not
directly support ECP EPP, but that windows 95 provides software support for
ecp epp.
    Therefore, i think the utilities are not useful, and are deceptive. 
Perhaps they work for other computers in the Compaq line but they do not
work in either of my two aeros, 4/25 and 4/33, nor in mmy son's

You once wrote, you don't have the pcmcia-floppy-drive. So dont bother
yourself with trying to install a diagnostics partition on your aero:
It is NOT POSSIBLE without a floppy.

This is because the Diagnostics-Setup (SP 2054)
recommends a clean, unformatted  harddisk to install itself onto. There
aren't ANY PARTITIONS allowed on it, otherwise you get the message "there 
is not enough space for the diagnostics partition".

The Aeros BIOS doesn't allow booting from any other device than floppy or
hdd so even a pcmcia-cd-drive won't work.

But with win 3.1 there is the compaq setup software for windows you may
install instead - with it you can change the setup settings from windows.
It's softpack SP 0891. Also the Win 3.1 Supplemental Software SP 1585 and 
SP 2041 may help. The 2041 was developped for the armada but worked fine 
on mine.

Personally, I now prefer to keep the diagnostic stuff on a 

Re-loading an O/S is much easier if you can first copy the 
source CD content onto the hard disk. Winlink is good for this
but another option is to format the HD in a desktop. You can
even go one step futher and install the O/S before you move the
drive. I did this to get W98SE on my Aero, transferring the HD
after first removing all the non-generic entries in Control 
Panel "System" e.g HD drivers specific to the desktop's
motherboard. Windows will find the required drivers when you
next start it up in the new systems (Aero).  I only did this so
that I could use the little Aero as a "server" to extend access
to my dial-up Internet connection to other PCs on my home LAN
which is a feature of W98SE. 33MHz is all you need.

Frankly, without a floppy I suspect you may be stuffed.

Subject: Diagnostics Partition Upgrade

I just upgraded the Diagnostics partition and thought that, since the
information in the FAQ is a little sparse, I'd let people know how it works.

1.  For Windows users, Compaq provides two kinds of diagnostics utilities.
One is Compaq Diagnostics for Windows.  The latest version I found is
version 1.12, revision D.  It can be obtained from the Compaq FTP server as
SP2640.  Installation is no problem.  In Win 95, a shortcut to Diagnostics
is placed in a directory/folder for Compaq Utilities.

The other kind of diagnostics runs at the OS level (more precisely, it
doesn't depend on a specific platform, because it brings its own MS DOS),
either from floppy disk or from the diagnostics partition on the harddisk.
This is what I just upgraded, and in the process, I ran into a problem or
two.  That's what the following is about.

2.  The Compaq web page (<>,
then select Portables, then Microsoft Windows 95, then Contura Aero, then
Contura Aero 4/33C) points in two different directions for the upgrade.
One is PC Diagnostics/Test, or SP2373, listed under ROMPaqs and System
Software.  The other is Computer Setup and Diagnostics for Portables, or
SP2054, listed under Utilities.

3.  The right one is SP2054.  Strangely, this is a more current release
(dated 11/6/96) than SP2373, which is dated 9/27/96).

SP2054 creates two floppies, one with the latest Computer Setup for
Portables, version 1.12 B, the other with the latest Personal Computer
Diagnostics, which includes the TEST, INSPECT, and RemotePAQ utilities, and
is version 10.11, revision C.  Both disks are needed to upgrade the
Diagnostics partition.

By contrast, SP2373 unfolds into only one disk, the Diagnostics disk, and
this is only revision B of version 10.11.  It doesn't make much sense to me
to download this, since the second disk, the Setup disk, is still needed,
but not included.

It took me a while to figure this out because one of the disk images I
created from SP2054 was corrupt and so I got confused by Compaq
instructions on the Diagnostics disks from SP2054 which can be read to
indicate that this Diagnostics disk from SP2054 wouldn't work with the
Aero.  But it does.

4.  The disks can be used for Setup or Diagnostics when booting from the
floppy.  That should come in handy after a harddisk crash, which I expect
to occur pretty soon on my Aero with the original 250 MB disk.  The disks
can be used to install the Diagnostics partition from scratch or to update
it.  Also, disks can be created from the Diagnostics partition.

Hope this is useful.

you must first unfdisk all partitions and then install the diagnostic

Subject: Rundown on Softpaq installation procedure

I have found that each SP****.EXE is generally accompanied with a corresponding
SP****.DOC file with some basic info and instructions. I have found they are
all the same though really:

  1.  get the .exe onto your system somehow
  2.  execute it and follow the instructions

They generally ask you to stick in a scratch floppy and reboot. I appreciate
that they generally store the previous/old contents of what they are replacing
back onto the same floppy so you can roll back if you want to later. If you
ever do boot your setup partition, I highly recommend making three floppies
while you are there:

  1. setup
  2. diagnostics
  3. minimal boot floppy (format a:/s) with goodies like format and fdisk.

There's a little menu to guide you though the first two. These have helped me
several times straighten things out such as for the new disk and when I
installed Linux.

different ROM image for the various different Compaq portables ... the one

Subject: 3.2.2 Power-Management


Subject: Problems when Power-up from standby

[Q] When I power back up from standby (in Windows) the mouse doesn't work again
unless I quit and restart Windows. Keyboard commands are fine, but the mouse is
frozen. This only happens after it has been in standby.

[A] The mouse problem is something inherent to the aero. To avoid it, don't
touch the mouse till you have come all the way out of standyby after hitting
the purple(tm) button. It should be OK then.

[Q] After starting up again from hibernation (ie., when I failed to get the
power plugged in at the very short power out warning :-( ), the screen blanks
out every few seconds. Only way to stop it is to reboot. Do others get this?


Subject: PCMCIA modems and Suspend/Resume crashing

[Q] When I come out of a long standby my pointer freaks out. It jumps around
and clicks on everything. I have to reboot windows. Anybody have similar
problems and a fix? (besides windows sucks)

[A] Don't touch the mouse till your Aero beeps at you that its awake.

[A] I think I may have a fix. I have the Windows power management stuff
installed; exit Windows, run SETUP, and make sure you're using a "DOS Machine
with APM" -- it may need a disk or two from the Windows disks.

      Check the POWER.EXE line in CONFIG.SYS -- I had to add "STD" to the end
     of it to prevent Windows from crashing on resume if I'd used the modem
     before suspending.
      In Windows, go into ControlPanels->Power and set it to "Standard" instead
     of "Advanced" (or turn it Off).
      I seem to have problems with the trackball if PCMSMIX.EXE is loaded, you
     may want to check it out for yourself. I'm not too clear on what it does.
     I had to comment out the PCMSMIX driver from CONFIG.SYS to avoid crashes
     and/or trackball weirdness on resume.

-- ed. note: PCMSMIX.EXE is not needed at all, see discussion elsewhere ...

      Another thing is to make sure the line:
     under the "[windows]" heading. Something took mine out a couple days ago
     -- I think it might have been the Lotus SmartSuite 3.0 install, but I
     can't be sure.
      Also, make sure WINDOWS\SYSTEM.INI is using COMM.DRV=SSCOMM.DRV and not
     COMM.DRV=COMM.DRV (or something else) under the [boot] section --
     Quicklink II changed this when I was trying out the Angia SafeJack PCMCIA

Test by booting the machine with the modem installed, access it somehow, quit
the comm program, suspend, wait a few minutes, and resume. If it didn't work,
your machine should crash -- otherwise you should be fine.

If it still doesn't work, you could try dropping back to the workaround I was
using and will probably go back to: turn off PCMCIA power except when you need
the modem. Put a copy of the PowerManagement&Hibernation icon on the button bar
in TabWorks. Double-click it, hit "." to go to PCMCIA setup, "f" or "n" to turn
power off or on as appropriate, then hit RETURN twice to get out. An
alternative is to eject the modem partially and reinsert it to get the PCMCIA
setup page (if you have "display window" set). Do this to turn it on, use it,
and do this again to turn it off when done.


Subject: Forcing hibernation

[Q] Does the aero support user-initiated hibernation? The skimpy hardcopy docs
and the SW is vague. The version of "compaq control center" we have is
inconsistent between the help pages and the SW. The help pages for power
mgnt->show settings lists a number of options that the software
(ctrlcntr->pwrmgmt/hib->show settings) doesn't have: modem, hibernation
timeout, AC HD idle, AC screensave. If nothing else, I'd be happy if we could
set the standby-to-hibernate threshold to a short period of time.

[Q] Does anyone know if it is possible to make the Aero hibernate without
getting a low battery first? I would have thought this would be a useful
facility (i.e., overnight), but haven't found a way to do it. Have I missed
something obvious?

When the machine hibernates a memory image is written to disk and the machine
switches off completely. Suspend shuts down most functions but still uses a
small amount of power. The problem with suspend is that it still drains the
battery if you leave the machine suspended overnight or some equivalent time.
(Incidentally, have you noticed the led flashing every so often when
suspended!). It would be nice to hibernate the machine if you know you won't be
using it for a while. It avoids having to close everything down and then bootup
next time the machine is switched on.

[A] Here's one for all of you Aero owners: on there's a utility
that tells the computer to hibernate when you press the power button (without
pressing function) rather than just going into standby mode. I remember someone
asking about this at some point. It seems to work just fine.

-- ed. Note: see

[A] I just put mine to sleep (suspend). It drains a little, but won't lose much
overnight. All it keeps alive are the RAM chips.

[A] There is an interesting point which some people might get surprised by. In
order for hibernate to work properly, it must be able to write the contents of
RAM to the hard disk quickly. Therefore, the space for this is set up ahead of
time; do a DIR/A C:\ and look for the file HIBRN8.DAT. You'll find a file that
is a little bigger than your RAM capacity; mine is 13,212,160 bytes.

What this means is that if you have an Aero wth 4 meg of RAM and add an 8 meg
RAM upgrade, HIBRN8.DAT will GROW by 8 meg or so. In other words, if you
upgrade your memory, you will LOSE about the same amount of hard disk space as
the amount of additional RAM you added. You could have problems if you added an
8 meg upgrade when you had only 5 meg of hard disk space. Also, this means that
if you become REALLY tight on disk space, you could turn off hibernation,
remove C:\CPQDOS\HIBRN8.EXE from AUTOEXEC.BAT, and remove the C:\HIBRN8.DAT
file. You wouldn't have hibernation, but you'd have an additional 4 meg of disk
space (or more if you have more RAM).


Subject: Spin down disk/disable powersaver when on AC power

[Q] is it possible to disable powersaver mode (i.e. set to drain) whenever the
unit is running off the A/C Adapter?

[Q] How does one get the disk to spin down automatically if AC adaptor is
plugged in? It would seem that the system goes into "drain mode" any time the
adaptor is plugged in - and of course, you cant change any of the values in
drain mode. I'm also still looking for some sort of TSR to spindown the hard
drive given some key combination. Does a program exist, can it be written?

Yes, there is a utility to spin down the hard disk. It can be found at I have called Compaq and found out that the softpage number 
for HDSDOWN3.COM is SP0414. I have it installed in my machine. Apparently,
the utiluty is only working with DOS not with Windows. The Compaq support

Subject: Is there a disk sleep hotkey?

[Q] I'm looking for some way to quickly spin down the disk. If I'm in a
situation where I know the disk won't be needed, it would be nice to be able to
shut it up on demand. Is there any way to do that now? Is it possible to write
a program that does this via ARM (or whatever)?

[A] Anything (almost) is possible. But for now just go into Compaq's Power
Management program while in windows,and set the hard drive spin down time to 1
minute. 1 minute later brrrrrrrrrrr Click It's fast, it's free ,it works, and

That's pretty nifty.  I think you've provided the answer.  I've set the
Aero to "Force APM 1.0 Mode" and Windows 95 Power Management to
"Advanced." All the problems I reported previously have miraculously
vanished.  In particlur, I note the following:

(1)  I let the Aero hibernate on low battery as well as forced hibernation
on AC power and on a well-charged battery (using STBY_HIB) several times.
Unlike before, waking up the Aero resulted in no crashes or any other
obvious problems.  This is true even for going into hibernation with my
IBM 14.4 Home and Away modem/ethernet card plugged in and with several
applications with unsaved work running, such as Word for Windows 95 or

(2)  I left the Aero in Standby mode overnight.  The clock and date
settings advanced normally.  (I didn't have a problem with time and date
before.  Perhaps the latest System ROM, dated May 16, 1996, downloadable
as SP1992 from Compaq, is the fix for that problem.)

(3)  The system seems to be cured from blank-screen syndrome when I plug
into AC power on a low battery warning.  Previously, the screen would
oscillate between on and off.  I would have to keep hitting keys every
couple of seconds to keep the display on.

(4)  The purple button seems to operate properly with any of the three
Windows Power Management Settings, Advanced, Standard, or Off.

(5)  The harddisk spins down and the display blanks the way they're
supposed to, after the time-outs set with the pop-up icons or in the
Control Panel.

(6)  Another detail:  The battery charge indicator on the Task Bar
functions better now.  When the charge is down to 20%, a red exclamation
mark appears to its right and the blue charge level drops to about
one-fourth.  I've never seen that exclamation mark before.  The charge
level used to drop directy from half-empty to wiped-out.

Jonathan, much obliged for your quick-fix answer to what seemed to be a
complicated problem.  I'm still ripping out my hair for not finding it
myself.  I believe I've been before to the well-hidden settings location
in the Device Manager to which you pointed us.  "Force APM Mode 1.0" is
the default setting, right?  I think I changed it deliberately because
Windows 3.1 compatibility mode sounded wroung, and then I forgot about it
completely.  Again, great suggestion!  I recommend this for inclusion in
the FAQ.

Now I'd be perfectly happy if it weren't for the remaining questions:

(1)  How does one keep Windows 95 from spinning up the harddisk, at
irregular intervals, and for no reason that I can see?

(2)  Is it possible to configure the Aero under Windows 95 to
automatically resume from standby when a PCMCIA modem card detects an
incoming phone call?

(3)  The battery charged to full while the Aero was in standby.  I then
powered up briefly, forced hibernation, and unplugged AC power.  Upon
waking up from hibernation on battery power, everything is fine except the
Win 95 battery gauge says it can't detect the charge level and displays a
question mark.  More precisely, it keeps switching between the question
mark and a reading of "critical" (battery symbol crossed out), prompting
low battery warnings that result in nothing.  Is this normal?

Cheers to all,

This fix is not a TRUE fix. The Compaq Aero has power management
built in to the system. However, The Aero does have problems in versions
win95, win95a. You must set it up to be compatible with version 1.0. Under
Win95b or Win97 you will have power management features version 1.2, which
also fixes the problems. The new problems with the battery explanation
mark in NORMAL for Win95 (under other Notebooks) but is not NORMAL for the
Aero. Why? Because the Compaq Aero is not designed around Win95. I posted
this fix you mentioned about one year ago. I have now sense noticed more
bugs than what you mention. I would also note that the Aero Runs much
better under the new v1.2 power management. JDS

Date: Thu, 06 Mar 1997 11:00:01 -0500

It is the same problem, in fact what I believe is the most common case
is when only the date advance is not working.  The reason being the
conflict between the Compaq and Microsoft power management utilities,
you can follow Gary's advice and turn the "standard" mode of MS Windows
power management to "advanced" to fix the date change.  At the other
hand, in "advanced mode" you get all those other problems that are
discussed in and, according to Gary again, "However, setting the
aero to advance will cause the aero to flicker in and out of power
saving mode at odd times.  Putting it in standard mode fixes this, but
you don't get the date advance.  Take your pick which bug you want"
(Aero FAQ list).

[C] There's a power management utility in windows hidden in the control
panel. This stupid utility upsets Aero's own power management. In
particular I had the microsoft thing set to "advanced" (don't ask me how
it happened or why :-) and whenever the Aero tried to shut down its disk
and/or the screen it failed! It was rapidly switching the disk and screen
on and off (a few minutes later however it would shut down both disk and
screen normally only to repeat the rapid on/off later). The rapid on/off
switch of the drive and screen got me worried if something was wrong.
Aero's power managment seemed OK. Finally I discovered that I had the
microsoft utility on. After setting it to off, Aero's power management
worked fine. Comments ?

[C] Well, I discovered a problem with setting the Windows/Control
Panel/power utility to "off" : aero does not go to hybernation when the
battery discharges. The proper setting is "Standard" ( not "advanced" ).
"Standard" means that the computer's own power management facilities are
in charge. Again "Advanced" creates problems in my Aero. Read the help of
Control-Panel/power for more info. Sorry for the confusion but it was
trial-error experimenting so far.

You need to set your power saving mode to advance mode for the clock to
advance.  It's under the control panel icon I believe.  However, setting
the aero to advance will cause the aero to flicker in and out of power saving
mode at odd times.  Putting it in standard mode fixes this, but you don't
get the date advance.  Take your pick which bug you want :).

Windows 95 comes with something called a direct cable connection--it
allows two computers to network over a parallel cable.  However, it is
not installed by default, so you may not have it.  Go to: Start -->
Programs --> Accessories and see if it listed.  If it is, you will need
another computer running 95 that also has direct cable connection
installed.  If it is not installed on the other machine, you will have
to install it by going to: Control Panel --> Add/Remove Programs, click
the "Windows setup" tab, and find direct cable connection under the
communications subsection.  You will need a special cable to make this
work.  Tell your local computer dealer what you are trying to do and
they can give you the right one.  If direct cable connection is not

Use Hyper Terminal with a serial data transfer cable for null modem
applications on COM 1. Open Hyper Terminal on the desktop and call the
session anything you want, then select Com 1 from the pull down menu in
place of your installed modem. Do the same on the Aero. To test, type AT
on the desktop, you should see the letters on the Aero. Then type AT on
the Aero and see if it shows up on the desktop. If it does, you're in
business. Then select send file on the desktop, and double click on a
.cab file in your WIN95 directory, then replace the file name with *.*
so the path is there, but now it send all files in your WIN95 directory
instead of the single file. For instance, C:\Windows\WIN95\
would now be 
C:\windows\WIN95\*.* and all files in the whole folder will now
Then name the directory where you want the folders to end up on the Aero
and hit send on the desktop and you're off. Hope this helps those of you
who don't want to invest in a CD Drive or network card to get the files
transferred. So far I have only tested this at selected speeds up to
19200 and throughput is actually at 1864 cps. VERY SLOW but if you don't
have a CD Drive and if you can't get DCC to work, this is just fine as
an alternative. BTW, I used Z Modem as the protocol.

I installed the trial version today from the link above.

1. You can't mix. Winlink 2001 cannot connect to the aeros winlink.

2. Winlink 2001 is much slower with the parallel port than the aeros
original winlink:
To transfer a114 KB jpeg file  winlink 2001 needed 12s
with the aero winlink (under win95 on both machines) it took 3s.
Much more waiting also with bigger (>2MB) files.

3. Under Winlink 2001 it is not possible to control the winlink program from
both machines: Either you run the filemanager like window from the desktop
or you run it from the aero.

4. There are no possibilities to change port settings etc. Connection is
only possible via the parallel port. Only possibilities are transfer,
synchronize folders, delete, rename, create new folder and refresh. Not
more. There is no 'properties' or 'options' dialogue. Features of the aeros
winlink like to search a file, to show a file, to change attributes, to copy
a complete harddisk with special selected directories, with files with
special attributes, or excluded files are not possible with winlink 2001.

5. If you exit winlink 2001 the program on the other computer keeps

6. There is no l2d or l2dmap like program. There is no small and quick dos

7. winlink 2001 seems to have some bugs too: The attached picture shows
different transfer progress states (file progress/total progress)  while
transfering only one file. I also had problems with the minimized program

8. All aero winlink files need only less than 1 MB diskspace, winlink 2001
needs 2.2 MB. So you cannot run it from floppy.

9. The trial version can only be used 8 times (not days).

The only advantage with Winlink 2001 are the long filenames. Aero users are
in many ways better off with their original winlink sofrware. All in all I
see no need to use winlink 2001 and delete it.

WinLINK Remote Install:

The winLINK program allows you to transfer data and share disk
drives between this computer and another. the other computer
is referred to as the "remote" computer. These instructions will
help you install WinLINK on your remote computer Quickly, allowing
you to transfer information from one computer to another.
NOTE: If you are using Winlink version 1.20c or previous versions,
the SHARE program cannot be running on the remote compueter during
the remote install or Clone procedure. Temporarily remove SHARE.EXE
from the AUTOEXEC.BAT on the remote computer, the replace it
after the installation is complete.

Follow the steps below to perform the remote install:

1. Turn off both computers.
2. connect the enclosed seral cable between the serial ports
of each coputer, (see below) :(
3. Turn both of the computers back on.
4. In tabWorks, select the Winlink tab, then doubleclick on the
winlink icon.
5. Click on the clone button near of the top of the screen, then
follow the instructions for preparing the remote computer to
accept the winlink program transfer.
6. when the remote computer is ready, click on the install button
on the winlink screen.
7. When the transfer is complete, you will see the message "remote
install has been successful". click on the Okay button.
8. Refer to he compaq online User's Guide for information on
copying data and sharing devices using winlink.

LAP2DESK quick setup

The lap2desk program enables one compueter to access another
computer's hard disks, diskettes, or pirnters through the serial

in addition to the documentation contained in Compaq online user's
guide, details information on how to set up and use the lap2desk
prograam. intially, the lap2desk program must be copied to the
remote computer usin the program's cloning process.

Follow the steps below to copy the lap2desk program to the remote

1. Turn off both computers.
2. connect the enclosed serial cable between the serial ports 
of each computer.
3. Turn both of the computers back on.
4. Exit windows (3.1) by selecting file, the exit on both computers.
5. on your local computer change the directory to winlink by
entering, at the C:\ prompt:
6. Run lap2desk by entering:
this loads the lap2desk driver.
7. Run the L2DMap program by entering:
8. Copy the Lap2desk program to the remote computer by selecting

Subject: Winlink

You can install Win95 from CD through Winlink.  I succeeded in doing so.
Here's a rough idea of how:

First, get a parallel laplink cable if you do not have one.
On desktop computer, in a DOS prompt (anywhere)

On your laptop add these lines to the Autoexec.bat:
C:\WINLINK\L2D /LPT1 e:=e:    (supposing that e is your cd rom drive)

Strip out anything that might interfere with Win95 install.
(i.e. I got rid of 386max, and multiconfigs, just to be safe)
Reboot your laptop.
You now can run the setup from the Cd on your desktop.

After the install completes, remove the L2D lines from the autoexec.bat.

All done.  =)
Kind of surprised me that it worked, but I'm not complaining.

[Q] At the end of last week I got a parallel laplink cable and tried it out
with my Aero. It works like a charm -- more than twice as fast as using the
serial port connection with the included cable. I would definitely suggest
getting a parallel cable for any significant data transfers, such as doing a
full backup of the Aero on a desktop system's tape drive. It took me 1.5hrs to
backup about 105 megs, as compared to 3 hours or more over the serial cable.
However, it's annoying to reboot the Aero to get rid of the L2D tsr. Does
anyone know how to pop that thing out of memory once it's running?

[A] I just use the Windows WinLink software over the parallel port with similar
performance results. Why are you using L2D? An even better deal is to use the
InterLnk.EXE and InterSvr.EXE stuff that comes with DOS - I use that for all my
backups - even to the point of making the laptop the "server" and backing the
data directly to the tape drive on my desktop. (I use Central Point Backup for
Windoze, but I guess any backup software would work.)

[I'm sure you know the drill - I put "DEVICE=InterLnk.EXE /Drives:3" in the
desktop Config.SYS and run InterSvr from the DOS command line on the laptop;
that way, the laptop C: drive magically shows up as drive H: on my desktop.]

[A] Try: l2d /free for any other question try l2d /? -- that will show a list
of other options.

Speaking of l2d, is there any way to both map the desktop's printer and drives
and the Aero's drive? I've got it to work for a while, but if both machines
attempt to access each others resources at the same time. Is there any other
software I might look at?

[Q] For some reason, my Winklink/L2D connection will conk out after a while. If
I try to reestablish the connection, the laptop will tell me that it can't find
the desktop, and both machines will begin to act sluggishly. Often I end up
having to reboot one or both computers.

Also, if I use L2D to connect to the desktop, the Aero will not let me access
the external floppy, even if I specified "b:" as the remote drive in L2D.
Unmapping the drive doesn't help. Again, the only solution is to reboot. Any


Subject: WinLink problems

[Q] I wondered whether WinLinks needs a special parallel cable. The story is as
follows: I purchased a laplink parallel cable (made by PC Accessories) from
CompUSA. This cable works fine with l2d / l2dmap (and the response is really
snappy as compared to using a serial connection). However, WinLink (and its DOS
counterpart WL) just get stuck in attempting to connect. Has anybody
experienced a similar situation? Is the WinLink cable different from the
standard parallel laplink cable? P.S.: I am running Novell DOS 7.0 on the host
(and yes, I unloaded everything except for the memory management stuff like EMM
and DPMS).

[A] I bought the exact same cable as you have (Actually, two; one at work, one
at home) and they work great. The only problem I've seen with WL.EXE (and, to a
lesser degree, WinLink.EXE) is that if I use, say, the serial connection at
115K to transfer to another box and then try to use the parallel connection to
the same (or even a different) machine, I have to:

      Start WinLink (without connecting to remote)
      Configure Comms to use LPT1:
      Save Configuration
      Exit WinLink
      Start WinLink

If I do this on both the local and remote machines, the parallel transfer works
fine; I can connect and transfer fine. BTW: Little known fact: You can run
WinLink (under WinDoze) and exchange files with a DOS machine that's running
WL.EXE. I couldn't get this to work for a while, and Compaq said it wouldn't
work, but after going thru the steps above, it does work. There seems to be a
bug of some esoteric flavor in the "connect" logic of both W*L* programs (I
suspect they share some "core" code.)

Actually, I really am not overly impressed with either of these products. I
like the fact that they're functional for a "Quick-n-Dirty" transfer to another
box, but in the main, I find that they are prone to hangage, lockage, and
buggage; especially when connecting to a really slow (386-16, for example)
remote. I get LOTS of transfer failures, both reading & writing.

For the most part, I use the InterLnk.EXE and InterSvr.EXE on the desktop I
connect to most. (You know, the ones that came with DOS.) I just put:
?DEVICE=C:\DOS\INTERLNK.EXE in my CONFIG.SYS and DOS asks me when I boot if I
want to load the driver; if I'm connecting to my "main" desktop, I tell 'im
Yes, and I'm connected! (I concede that this is probably a religious
preference; flames to /dev/null, please!)

What I'm most impressed with is the new "Direct Cable Connection" stuff that's
in Chicago/Win'95.... (What are they calling it today?) This lets me connect,
via the parallel cable, to another machine running Win'95 and use it as a
gateway to all of the network resources that the desktop is connected to. I can
use printers, local and network drives, CD-ROMs; whatever the desktop can see
on the network. Really slick.


Subject: Network File System (NFS)

[Q] I'd be interested in any freeware (or shareware) NFS server programs for
the Aero under DOS. I've use XFS (client) a little; works pretty well with the
exception that it seems to choke and hang the machine if too much data comes
across the net too quickly (like doing a "tar xvf e:aero.tar").

[A] Yeah, I've been thinking about this for a while - I never got XFS to work
quite right (but this was an old version - maybe 7 months ago?), nor PC-NFS,
nor any of the others. But in defense of these products, I didn't try TOO hard.

One thing you probably want to look at is the rsize and wsize NFS params - I've
had a lot of trouble with NFS (on a lot of different platforms) unless I use
1024 for both read and write size. (This seems to be a problem with the whole
NFS world - Doesn't it stand for "Nightmare File System"?)

[A] I had XFS working ('til I wiped my OS/2 2.1 desktop and installed Warp; I
haven't put the tcp/ip NFS back on the desktop yet) for the most part. It just
seemed to hang the machine partway into reading a large file from the desktop's
hard disk. Writing to the desktop worked fine; I could use TAR or ZIP to backup
the laptop C: to a file very quickly.

I never did put much effort into it because what I really needed was an NFS
server on the laptop, so I could backup/restore the Aero's hard disk from the
desktop system's tape drive. I'll have to look at rsize & wsize -- maybe they
were causing the problem.

It won't, at least not the non-DOS diagnostics partition.  If you try to
run the diagnostics diskette with the HDD in the desktop computer,  the
installation program will recognize that it is not running in the Aero,
and will refuse to install on the HDD.  At least, that was my experience.
In order to install the diagnostics partition the hard disk must be
already installed in the Aero and so you will need the floppy drive.

The bottom line is that you can fdisk and format the disk in any computer
you wish and it will then work just fine in the Aero.  I did that a year
ago and have enjoyed the increased disk capacity and haven't missed the
diagnostics partion one bit.  If you later decide you want the
diagnostics, you can always buy a floppy drive and run the diagnostics
program from it.
You don't even need to reformat the hard drive.

Subject: Speak.exe install explanation

Here's a better explanation of how to install speak.exe into an Aero with WIN95

Quote from Microsoft:
Speak.exe contains a Microsoft Windows sound driver that allows most
.wav files to be played on the
PC speaker on most computers not equipped with a sound card. This
article describes how to obtain, install, and use the PC speaker driver
with Windows 95 and Windows 98. 

Download the Speak.exe file to an empty folder, and then double-click
the Speak.exe file to extract its contents. Make sure that you do not
extract it to a /windows or /windows/system directory. I just made a new
folder in C: called Speak.

To install the PC Speaker Driver, use the appropriate method: 

Windows 95: 

1.Click Start, point to Settings, click Control Panel, double-click Add
New Hardware. 

2.Click Next, click No, and then click Next. 

3.In the Hardware Types box, click Sound, Video, And Game Controllers,
and then click

4.Click Have Disk. 

5.In the Copy Manufacturer's Files From box, enter the full path for the
folder containing
the Speak.exe file and its contents. Click OK. 

6.Click Sound Driver For PC Speaker, and then click OK. 

7.Click Finish. 

8.When you are prompted to restart your computer, do so.

[Q] Has anyone had luck running the PC Speaker driver for Windows? I've tried
to no avail. The driver loads fine, but doesn't do anything. In setup, I can
change the few options it gives, but the test button is disabled.

[A] I had the same problem with it. It turned out that I had removed all the
wave files from the system many moons earlier to save space (no soundcard, why
waste space on sound files?) and I forgot about it. I reloaded several waves
from my desktop in the c:/windows, including DING.WAV (or is it BELL.WAV) which
the test button uses, and after the files were there, the test button started

Have you tried playing any files with a player like WPLANY.EXE or with the
sound recorder applet? They should work ok as long as the driver is properly
installed even if the test button isn't there. Mine did. The documentation
mentions that media player worn't work with the speaker driver. Anyway, I've
had great luck with it playing WAV, VOC, and AU files from the web. It even
does sounds for some games, though it causes all animation to pause.


Subject: PCMCIA stuff

[C] From: Martin Ramsch <>
Date: Sat, 3 May 1997 21:17:37 +0200 (MET DST)

But for all the fellow Aeronauts who are still running Win 3.1 this
might be interesting:

Older versions of the PCMCIA software have a bug, that forces you to
have ATADRV.EXE in the CONFIG.SYS, if you want hot plugging of the
floppy drive.  The floppy drive will work without it, too, but not
after removing and reinserting the floppy drive.  (Unfortunately I
didn't make a note of my former version numbers, but it was the stuff
already installed when I bought my Aero.)

Normally you wouln't need ATADRV.EXE, as it's intended as IDE/ATA card
driver only.  And it has the nasty side effect, that you get a
superfluous drive letter.

Win 3.1 users should upgrade to SoftPaq 1645 (thanks to Kevin Stock).
This installs new versions of the PCMCIA software which solve these

Subject: SP1473 Updated PCMCIA support

I have been messing with the Softpaq, SP1473, downloaded from,
and would like to let everyone know my experience.  This Softpaq contains
PCMCIA drivers and a program, Systemsoft CardWizard verion 1.00.02

Prior to installing this, I found that there was an annoying bug, such that
after using the modem, I could not swap in the floppy drive.  IF I tried, the
floppy would not be "Configured" by Cardid.exe, and would not work unless I

With CardWizard, there is a section to "show ranges." If I set it to show
"included" then add 03F0h-03F7h to the included range, the problem goes away.
Just thought you all might like to know.

Oh, Win 3.1, the one that came with the aero.  I also found that, after I
made the fix I mentioned previously, that the modem would not work if I: used
modem, swapped in the floppy, then tried to use the modem again.  So, I
rebooted, inserted the modem, checked the Card Wizard to see that the modem
used 02F8h-02FFh for I/O, then marked that range as reserved.  Now, it seems
that I can swap back and forth infinitely.


Subject: Problems with Modems/Serial Devices

From: Philip Wilk
Date: 27 Jun 97

The original communications driver that came with windows does not allow
for high speed serial port use. This is due to non-idenification of the 
FIFO and poor time sharing of the processor. The original commdrv will not
let you run your modem at 28.8. Things to do to fix things:

   1) Add COM1FIFO=1 to the [386Enh] section of the window's system.ini file

   2) Replace commdrv with a better driver. I suggest You do
      this by changing the commdrv=commdrv line in your system.ini file to
      something else, like commdrv=cybercom.drv for instance. CyberCom is free
      and can be found around the internet. There are other ones avaliable, 
      like the one included with winfax.


Subject: 32 bit disk access or no?

[C] From: "Ulrich Hansen" 
Subject: SOLUTION: The 32 Bit disk access with the aero
Date: Sun, 23 Sep 2001 05:25:49 +0200

Hi all aeronauts,

even in these war-time like days I puzzle around with the aero AND:

I finally solved the 32-Bit-Disk Access-Problem with the aero and gained 
now 32 bit disk access (32BDA aka "Fastdisk") under Windows 3.1 with my 
4,1 GB Toshiba drive.

The topic is also described as thread "32 bit access" in this group and as
chapter " 32 bit disk access or no?" in the faq. AFAIK there hasn't
been a solution until now.

Products affected: Windows 3.1/WfW 3.11 systems on aeros with harddisks
larger than 504 MB.

So here is the way I made it work on my computer. It worked for me, maybe 
it doesn't for others.

My Basis
Contura Aero 4/33, 20 MB RAM, Harddisk: Toshiba MK4309MAT, 4,1 GB
Operating System: Two OS via PowerQuest BootMagic Bootmanager:
- Windows 95B
- Windows 3.1
(The 32BDA-Problem only exists in Win 3.1. The Windows 95 partition and the
bootmanager don't play a role.)

The OS
Windows 3.1 is updated to the win32s 1.30c from It is also updated to Windows
3.11 (not WfW) using the update package "ww0981.exe" available from
microsoft ( I
also use the fix1MB solution to prevent windows 3.1 to give away all its 
<1 MB Memory to applications. And I use the syshook.drv for getting a more
stabile system. More about fix1MB and syshook see .

The compaq files
I updated Windows 3.1 with the Compaq Windows 3.1 Supplemental Programs SP
1585, SP 2041 and sp2774. All of them include two files that give you 32BDA
with the aero on <504MB Harddisks - those files are "cpqint13.386" (which
replaces Microsofts "int13.386") and "cpqwdctl.386" (which replaces
Microsofts "wdctrl.386").

The problem
32BDA is limited to hard drives with 1024 cylinders or less (504MB or less).
After installing a bigger than 504 MB hdd on the aero, the 32BDA doesn't
work any more. Instead you get (with the start of Windows) the message:

"CPQWDCTL Error WD4: The Microsoft Windows 32-bit disk driver (CPQWDCTL)
validation failed at phase 08, 10. Press any key to continue without using
32-bit disk driver."

You can control if the 32BDA is used, if you start the control panel, choose
386 Enh and click on Virtual Memory: If 32BDA is ON it says "Type: ... (uses
32-Bit-Access)". If the 32BDA is OFF, it says "Type: ... (uses BIOS)". That
means, Windows has to switch to real mode if it wants to access the hdd √
what costs time and gets you "Out of memory"-Messages (Windows needs <1MB
memory to switch into real mode).

If you are in control panel/386enh/virtual memory and choose change and you
see a checked "32-Bit Access"-Box, that doesn't automatically mean that the
32BDA is really used.
About the advantages of the 32BDA see

The solution
Even the newer compaq softpacks (f.i. SP 4603 from 1997 intended for the
armada) don't include a compaq driver that is able to give you 32BDA on
>504MB hdd.

Microsoft either doesn't have a driver to solve the problem. MS instead
tells you in its knowledge base articles to the 32BDA-problem (collected at ) to get a driver from your
harddisk manufacturer.

If you have a SEAGATE-hdd you can try seg32176.exe, available at
If you have a MAXTOR hdd, try win32bit.exe, available at
If you have a WESTERN DIGITAL hdd, try win31.exe available at
If you have a TOSHIBA hdd YOU MAY try eide32.exe, available at (But see the mentioned problem 

Functionality: These hdd-manufacturer drivers normally install in the
windows\system directory and run themselves via the [386Enh] section in the

They replace (but don't delete) the windows or (on the aero) the compaq
32BDA files. The lines in the system.ini for the compaq drivers

are replaced (f.i for the seagate driver) with

You have to check, if the old drivers (cpqint13.386 and cpqwdctl.386) are
really REMd out with "REM" or ";" in the system.ini. If not, you get (with
windows start) the message "there are two devices for int13..." or anything
like that and you have to edit the system.ini and rem it out by hand.

Sometimes the microsoft driver int13.386 (called with device=*int13 or
device=int13.386) isn't included in the driver package. If you get an error
message, you should be able to replace the line in the system.ini again with
the compaq driver "device=cpqint13.386" and everything works... I am not
totally sure with this, because I have a toshiba drive and this is a special

Unfortunately on my aero √ and I suppose on everybody elses aero √ the
Toshiba driver doesn't work. Instead you get (with windows start) the error

"Fail to find the Toshiba signature. This Microsoft windows 32-bit disk
driver (TOSHCTRL) only works on Toshiba Systems. To continue starting
windows without using the 32-bit disk driver, press any key."

There is nothing you can do about this. Obviously Toshiba doesn't care about
people who are using a toshiba drive in a non-toshiba-system.

But there is a way to work around the problem. The OnTrack 32BDA driver
ontrackw.386, available at
is supposed to work on ALL drives, indepedent of its manufacturer.

Use the above mentioned source or get (like I did) the Ontrack disk manager
for windows, ver. 3.00, run the "Advanced hard drive Installation" Option
and choose "Install Ontracks 32-Bit disk access".

The Ontrack drivers "ontracks.386", "ontrackw.386" and the "int13.386" file
are now copied to your windows\system directory. The drivers are called up
by the [386Enh] section in the system.ini:

After doing so, the 32BDA worked fine √ except...

Windows 3.1 run fine with 32BDA but everytime I started a DOS-box (window or
full-screen) the aero rebooted. This problem was obvously dependent of the
32BDA, because when I unchecked the "Use 32BDA"-Box in
control/386enh/virt.memory/change and restarted windows, the DOS-box run
with no problem.

What was funny: When I started Windows with enabled 32BDA, ran Word for
Windows 6.0 first and then started a DOS-Box there was no problem at all.
Even when I ended Winword and started the DOS-Box everything worked like 
it should.

I am no programmer, so I am not sure, what the problem really was. But the
winword/DOS-Box behaviour made me think, that perhaps there were some older
dlls in my system and the DOS-box used these older ones. But after winword
enabled the newer ones, the DOS box obviously uses these libraries √ with
success. Is this possible? Perhaps you know... But in the end it lead me to
the now working fine solution. Maybe some of you will think it isn't a
solution at all but a new problem, but it isn't this to me:

available at (8,8MB)

After doing so, most windows 3.1 DLLs were updated to a date around 1998
(Checked it with the winword system info). And voilЮ: Windows runs with
32BDA. Directly after Windows Start I am able to start a DOS-Box without
problem. Every other application (Word, Corel Draw) run fine.

This is a really hard way to solve the problem. But after all, it was the
only way it worked for me. Maybe with the newer wfw 3.11 (which I don't
have) the dlls are better and you don't have the dos-box problem. But for
me, this was the final solution for my 32BDA problem on the aero.

Installing the IE 5.0 was not a big problem, but it had two difficulties:
After installing the files and rebooting the system the ie50 began
"preparing" its files (the little box at the left side of the desktop). But
when it came to the file "msador16.dll" there always came a "General
Protection Failure" (GPF) saying the install program caused a GPF in the
file "win87em.dll". I directly shut down the aero by FN+OFF (and so
prevented the install program to terminate itself) and began searching for a
solution. In the internet there are newer microsoft versions of the
win87em.dll but none worked. So I ended up, renaming the file msador16.dll
to msador16.old. Next time I started windows, the install programm worked
fine, complaining one time about the missing msador16.dll but making its
work with all the other files. Afterwards I renamed the msador16.old back 
to .dll and had no problem further.

The second difficulty was my old mouse-driver. In 1996 I had replaced the
original compaq/logitech driver with the microsoft mouse driver V.9.00
because of the the bigger pointer and the "jump-to-standard-button" 
But this driver doesn't work very good together with win32s (what the IE 
5.0 uses very much), so everytime I started the IE 5.0 I got the 
"growstub"-GPF, best described in 
I finally uninstalled the microsoft mouse driver and installed the updated 
compaq driver (softpack SP 1714) which comes with all the microsoft 
features but works much better with the aero.

Hope that helped

I had the same problem after upgrading my HD from 170Mb
to 2.1 Gb. The quickfix I found (after reading the FAQ
where they said 32-bit disk access might create problems)
was to:
 1. open my \windows\system.INI file using textpad
 2. go to the section called [386Enh]
 3. assign the "false" value to the control variable 32BitDiskAccess
    (it now reads  32BitDiskAccess=0 )
 4. be happy with the result

It might be wrong advice, but I had no problem at all after that

If you use 32 bit access you'll have problems with "hdsdown3".  This utility
shuts down the hard disk on demand or at specified intervals after last
keypress.  If you don't use this utility (available on wade's
site or compaq) then go ahead and use 32 bit access.


Subject: Windows for Workgroups

It appears that Windows for Workgroups 3.11 works on the Aero. 32-bit file
access also appears to work without a problem.

[Q] WFWG Hangs my Aero. Anyone else have this problem? It seems to work fine
though setup, but then it hangs on restart.

[A] You have to get a new keyboard-driver. It's called CPQVKB.386, and can be
found at To install 
the cpqvkd.386 device driver:

1.  Exit Windows.
2.  Copy CPQVKD.386 to your WINDOWS\SYSTEM directory.
3.  In the \WINDOWS\SYSTEM directory, use any text editor such
    as DOS Edit to change the following line in the [386Enh]

4.  Save the SYSTEM.INI file.
5.  Restart Windows so the change takes effect.


Subject: Speaker Driver

[C] A cheap way to get sound with windoze is to use the Aero's internal
speaker. All you need is a little dittle from Microsoft that they do not send
with windows. The file name is speak.exe. Its the driver for the internal
speaker. You get real sounds, not just beeps. The quality depends on the
internal speaker ... the aero's is OK.

to add to Phillip's comments I have found that there are differences in the

The most annoying problem is that my IBM Home and Away PC Card (Combo
Modem & Ethernet card) works fine under Win95a but Win95OSR2 refuses to
recognise it.

I have also noticed that some PC cards (Adaptec Slim SCSI 1480 which is
cardbus and not supported on the Aero anyway) specifically require
Win95OSR2 to work.

In summary - you don't necessarily need the latest version.

Subject:  FAQ, Nokia Data Suite, and Re: WIN 3.1 to WIN95 on Aero?

They (Microsoft) never released OSR2 to the general public. The only way
you can get it is to borrow the installation CD from a machine that has
it already installed from the factory.

The reason for this, to the extent that I can figure out, is the OSR2 was
not rigorously tested on all machines and platforms. Surprisingly enough,
MS does do bug testing. I guess to separate out acceptable bugs from bugs
that must be fixed prior to release.

I am doubtful that there is any improvement to win95, going to OSR2. The
caveat is that you must download and install all the patches from the MS
web site if you do not have OSR2. OSR2 has all these included, and then
some more "fixes" (hacks?). I personally chose win95a over OSR2. It works
just dandy - albiet slow slow slow.

Switching to windows 95 is a tempting idea. However, it is important to
remember that it is not a trivial project and will take many hours;
especially the first time (doh). If you do not need windows 95, I would
not go to the trouble "upgrading" till windows 98 comes out. There is
precious little advantage to running this operating system versus windows

Make a complete backup before you install. If you do not install over
a current version of windows you will lose all your registry entries. This
may not be a bad thing if your reg.dat file is huge. Losing your old
reg.dat entries means some programs will not work right unless you
re-install them.

If you do not like the new windows, you can remove it even if you do not
have the uninstall option. Here is how:

1. Boot from an old DOS floppy.
2. Delete the windows directory.
3. Restore your old windows directory.
4. Use the sys command to transfer (DOS) to transfer the system back over.

This should restore your old windows.

I posted an update to my earlier message a while ago.  I now agree that
Sp3030 works fine with the Aero.  I have not seen any problems with
hibernation that I could specifically trace to either Sp3030 or Sp1329. In
addition, Sp3030 may work just fine by itself, unless you have that nasty
problem I reported, which appears to be fixable (or at least was fixable in
my case) by hitting ENTER in Control Panel--Energy--Hibernation.  And yes,
Sp1329 seems to work fine over Sp3030, though I'm not sure you would want
Sp1329, since Sp3030 is an update.  (Of course, Sp1329 gives you the Compaq
PCMCIA Card Manager, and I have it installed on my Aero, but I don't really
see any truly useful functionality in it.)  I can't see why you would want
to delete any files from the more current Sp3030.  And sorry, but the
Registry is outer space to me.

Hope this helps.

Subject: SP3030 and hib32.exe

Here is what helped getting hibernation to work after first installing
SP3030 (Portable Supplemental Programs for Win 95, version 2.04 rev.
B--Armada stuff) and then SP1329 (Portables Win 95 Supplemental Programs,
version 2.00 rev. B--Aero stuff).  It turned out to be very simple for me,
however, I don't know if it will always work in similar situations.

As reported earlier, unless I kept the old hibrn8.exe in the \CPQDOS
directory and had it loaded in autoexec.bat, the newly installed SP3030
would screw up the hibernation receptacle (hibrn8.dat) and then
practically hang in the futile attempt to create a new one.  I'd also get
out-of-disk-space error messages.

So, after boot-up, the only way to stop hib32.exe from doing who knows what
and tying up the Aero in strange loops was to hit CTRL+ALT+DEL and kill it.
 Then I deleted the new but corrupted hibrn8.dat (which in this case had a
size of zero KB).  Next, I opened the Control Panel,
                                        then Energy,
                                                then the Hibernation tab.
There, I found the box with the name "Drive for Hibernation File."  It list
drive C: and the amount of free space on that drive, plus the amount of
space needed for hibrn8.dat (not sure if the numbers actually made any
sense in my case previously, but they are correct now).  I clicked on the
box to see if anything could be reconfigured, but there weren't any other
options.  BUT, this time, I didn't hit CANCEL to exit Energy, but OK. That
apparently made all the difference.  The harddrive purred nicely for a few
seconds produced a new hibernation file, of the correct size (some 12MB).

That was all.  I have removed all of \CPQDOS, rem'd out the hibrn8.exe line
in autoexec.bat, and have been working without any problems since then.
Hibernation is flawless.  I am now under the impression that the order of
installation (SP3030 first, then SP1329) doesn't really matter.  I would
even speculate that SP3030 by itself might work fine, so one could probably
do without installing the funny Compaq PCMCIA Card Manager that comes with
SP1329 but not with SP3030.

Hope this helps someone.

I had the same problem for almost a month and all the calls to Compaq
and Microsoft were to no avail.  I had followed all the rules and
suggestions just as the above poster did.  It was extremely
frustrating.  The problem ultimately turned out to be a driver from the
16-bit version of the Colorado Tracker.  What you need to do is to first
run it in safe mode, and see if the problem occurs.  If it doesn't, then
you are lucky, since you are on the way to solving the problem.  Remove
all the other applications -- even the ones that you didn't know you had
since you hadn't used it for a while and test the working of the
floppy.  If you have the old Tracker, that is almost certainly the cause
of the problem -- you need to get rid of that driver and install the
32-bit Win 95 Tracker driver.

Hope the above suggestion works out.

If I may make a suggestion.

    Rename your autoexec.bat and config.sys files so they don't run
during startup. (You can call them anything, but autoexe.ba_ and
config.sy_ is simple and minimizes confusion).  Then restart Windows 95.
It will recognize your drives and load its own 32 bit drivers where

    There doesn't seem to be much use for the autoexec.bat or config.sys
files as Windows keeps track of such things automatically.  The only
time you need these drivers is when you run a straight DOS session from
startup.  I find it much easier to just open a full screen DOS window
from Windows 95 and not worry about it.

Good luck.

Subject: The path to '95 by copying setup to the aero

From: Steven Lawson <>
Date: Thu, 23 May 1996 12:06:59 -0700

Yes, this really does need to be documented in a step-by-step
format.  I've had mine on Win95 since beta so it's hard to
recall everything.


Seems to me the sequence would be (assuming no cd-rom on the
Aero and a cd-rom Win95 on a desktop, plus the Aero floppy
NOT installed)

  1. Backup everything
  2. Update the BIOS
  3. Remove as much as possible
       (you CAN remove Win3.1 if you have the floppy and
        map the desktop A: drive in step 7) 
  4. Rename the WINDOWS directory if not removed
  5. copy INTERLNK.EXE and INTERSVR.EXE to root (\)
      (Win95 has none & you'll later toss \DOS)
  6. add INTERLNK to config.sys 
      (use /LPT1 /AUTO)
  7. on desktop:
      copy cd \WIN95 subdir to hard drive
      run INTERSVR /LPT1 /X:A /X:B
      (no /X:A if you erased Win 3.1!!)
  8. connect parallel cable & boot Aero
      (verify drive mapping)
  9. XCOPY the \WIN95 subdir to the Aero
 10. go to \WIN95 and SETUP

Install new Windows into /WINDOWS.  Eventually it'll finish
the install...  If you erased Win 3.1 you'll have to put
the 3.1 disk 1 in the server A: for verification.  I leave
the Aero floppy out so Win95 won't see it during setup and
hopefully it's the reason I've had less trouble than others
getting the floppy to work later..

If you can try and keep the \WIN95 subdir for a few weeks, it's
likely you'll reconfig something and need it available..

Since you want drive compression I'd get the Plus! pack
for Drivespace 3, it works great.  Do the same trick as
you did pulling the \WIN95 subdir before. (I leave
INTERLNK in config.sys with /AUTO on mine, it comes in
REAL handy.  'Direct Cable Connection' in Win95 sucks.

Someone else will have to assist on the order of the
updates.  There is also a step to do to make sure Win95
doesn't have a default floppy driver loaded which messes
up the PCMCIA one.

Eventually you'll want to remove the \DOS and old windows
subdirectories.  Make sure you placed copies of INTERLNK
and INTERSVR into root or you'll lose 'em (and they're
too handy to lose!)
Hope I didn't leave anything out, but I likely did.  There
are other ways to do this but this is what I've found 
works well (at least the few times I've done it..)

I haven't looked there recently to know if the Win96 upgrade info as
been updated, so here's the Win95 list of upgrades I used in January
1997.  Obviously there may be newer upgrade files available.  Other
than not yet having the 32-bit hibernation program, I'm quite
satisfied with the results.

What I used to upgrade to Win95:

    16 Megabyte RAM
   722 Megabyte hard drive - selected price/budget, not price/performance

   Compaq Aero upgrade software:
        384313 Dec 12  1996 sp1992.exe  ROM

         41592 Dec 17  1996 sp2158.exe  LPT port utility

        Win95 ran ok with 12Mb, however I am installing Linux & a Web
        server for portable presentation of a Web project my wife & I
        are doing.  

        I had to fiddle with the master/slave jumper on the drive to
        make it work properly.  The jumper definitely was required.

        The 722Mb disk arrived already formatted.  I unformatted it
        using fdisk to delete the partition.  Only then did the Compaq
        setup program do "the right thing".  The diagnostics partition
        from 2Mb to 4Mb, or thereabouts.

        File date is when I downloaded, NOT the file date at Compaq.

        I downloaded these files from:

        Whether or not the appropriate URL is still the same is a
        function of Compaq, not me.  The "_Areo_" typo is in my "save

Subject: My SoftPaqs recommends for Win95 and Aero

Hello list,

Well, Win 95 is installed and running on my Aero/25 with 12meg ram and the
little 170Meg drive. 
-APM functioning, suspends with button and by itself at medium and high
-Hibernate worked but currently off so I would have more than 1meg free space!
-Direct Cable Connection is working, although my desktop doesn't have an
ECP port so Aero's ECP is connecting to std LPT.
-Briefcase working, although not quite sure how to best implement it yet.
-PCMCIA hot swap functions with my IBM 14.4 modem card (its the only one I
got!) and series 2 floppy I'll be returning tomorrow. Occasionally inserted
cards won't be recognized. Occurs when Control Panel/PC card
(PCMCIA)/Resources gets set to manual config somehow (I did it once, and
now whenever I install a new software component it reverts to it).
Solvation is to enable Use Automatic Settings.

SoftPaqs Used:

-SP1992.EXE - RomPaq to upgrade system rom to 5/16/96
-Computer Setup for Portables Rev 1.11G - Upgraded Diag Partition.
-Computer Diagnostics Rev 10.07B  - Compaqs website now includes a locator
which lists the latest Diag version as 10.10C, but there is no English

-Disabled (rem off) everything except for Himem.sys, EMM386.EXE,
SmartDrv.exe, (wasn't using any disk compression drivers) Lmouse.exe.
(using version 6.60, Compaq has Version 6.46 dated August '96 on their web
-Added l2d.exe and l2dmap.exe at end of autoexec.bat to enable me to run
setup off my Win95 setup "CDRom" on my desktop. Once I got Direct cable
connection working I deleted those entries.

SP1329>EXE - Supplemnetal Programs for Win95 Ver 2.00B (specified for Aero)
I tried Ver2.03A & 2.03B which are slated for the Armada and I don't
recomend them. Version 2.00B integfrates with your other controls much
better and includes a PCCard manager for protected mode Win95 that works
well. The Armada files were inconsistant in the Aero environment and the
contols were a pain! 
-There is no need for any other PCMCIA support files like CardWorks, etc. 

Currently my CONFIG.SYS file has only 6 enabled lines (and 20+ disabled
ones!) HIMEM, EMM386, FILES=, DOS=, FCBS=, SHELL=.
Likewise my AUTOEXEC.BAT file has only 5 enabled lines - Set Path=, Set
Lmouse=, Set Prompt=, Set Temp=, AND C:\CPQDOS\HIBRN8.EXE (added by Sup
Prog Ver 2.00B setup) Hib32.exe may work just fine, but who cares if your
computer completely shuts you out 23 nano-seconds faster.

Subject: Hot-pluggable Floppy Drive in Win 95  [Was:  Win95 Minor Glitch]


yours is a problem that has been discussed here before.  Here is an excerpt
of what I posted earlier to a similar inquiry.  Don't know if it's in the
FAQ yet:

I.  Here is how to get the FDD working.  I had some problems with the FAQ,
too, and I think it's missing an important step or two.  First of all, I
wouldn't be concerned about the Compaq PCMCIA Controller (which is in
Device Manager, under the PCMCIA slot item--note that I have the German
version of Win 95, so some of the English designations I'm using may not be
accurate).  If you think you might have screwed up the Compaq PCMCIA
Controller settings already, it could be a good idea to simply delete it
and have Win 95 reinstall it automatically on reboot.  Secondly, I'm
assuming that you have FDD problems only when you try to hot-plug the
drive.  Win 95 shouldn't have any problems with the drive when it is
plugged in at boot-up.  (If it does, please give more details of the
problem.)  Step 5 below should be the most important one for you.

1.  With the FDD plugged in, open the Control Panel/System/Device Manager.
You should see a "Floppy disk drive controller" item (or whatever it's
called).  Double-click on it.  It should display a "Compaq floppy disk
drive controller" (or the like).  Remove it by hitting the "Delete" button
or key.  Reboot.  Make sure the FDD is not plugged in while rebooting.

2.  When Win 95 is up, plug in the FDD.  Win 95 should automatically
detect the drive as new hardware and install the drivers.  Answer yes when
asked if you want to reboot.  Again, have the FDD unplugged while booting

3.  When the system is up again, plug in the FDD.  You should hear a brief
grinding noise from the FDD.  Try if you are able to access the FDD.
Probably not.

Open the Device Manager.  (If you hit the "Refresh" button, the Compaq PC
Card (PCMCIA) Manager--if installed from sp1329--should pop up and report a
device conflict.)  You should see the FDD controller item, branching out
into the Compaq FDD controller, which will probably display a yellow
exclamation point, indicating an error.

4.  Double-click on the Compaq FDD controller to open it.  You should find
a few lines on the "General" tab saying that there is a resource conflict.
Also, the box at the bottom of the configuration window should be checked.

5.  Hit the Resource tab.  Press "Configure manually."  (I glean from your
question that you may have been this far already.)

Now press "OK."  That's right, without changing any settings (you can't,
anyway).  That's IT.  I found this apparently crucial step very confusing
when I first upgraded to Win 95.  Magically, the FDD will now be configured
automatically, once and for all.  You will hear the characteristic
double-beep, and the Compaq PC Card (PCMCIA) Manager will pop up (if
installed) and report that the FDD is properly configured.  The FDD is now

6.  In addition, you may want to check the Resource tab again.  It should
report strange settings, but no conflicts.  Press "Configure manually."
Note that there are now four configuration settings, 0000 through 0003
available (where there used to be only one) in the little drop-down

Also, the check box "Set automatically" should be available, but
unchecked.  If you check the box and reboot (but don't--never touch a
running system...:-}), you'll likely be back to the old problems.

Strangely, at least in my case, the bottom section of the Resource tab
indicates a device conflict at I/O address 03F0-03F7, supposedly used by
the Compaq IDE controller.  But I have not seen any problems.  The active
configuration setting is "0000."  Surprisingly, when I changed this to
0001, the device conflict message went away, but--the FDD again wouldn't
work!  (Settings 0002 and 0003 seem to be "out of service;"  0002 is the
same as 0000, and 0003 is the same as 0001.)

Hope this helps.

If I remeber correctly...
There are 01*** FDD's and 02*** FDD's.
If you have a 01*** FDD, I think you have to install the supplement
file/program cpcm.vxd. I called Compaq before I installed Win95 and
they sent we all the upgrades I needed, PPP/SLIP connection was down.
I think that is the only choice if you have the 01*** FDD.

If you have a 02*** FDD, I think Win95 aitomatically installs the
Compaq PCMCIA controller under:
        My Computer/control panal/system/device manager/PCMCIA socket.
So all that you have to do is uninstall/remove the other controller
that is installed under there as well.

Hope this helps (and is right),

You MUST use a TRUE null modem cable.  The DCC Troubleshooter for Win95

You do not have to modify your msdos.sys file, you can just do the F8 boot
thingy when you need to boot to Windows 3.x. Also, do not fiddle with the
.w40 files or you may accidentally prevent yourself from booting back into
Windows 95. Read the entire section fully. Only mess with the mentioned
system files from the version you want the changes to affect. What I mean
by this is, if you want to have your autoexec.bat operate differently when
the previous DOS version boots, only edit this file when you have ALREADY
booted to the previous version. Be very careful with the msdos.sys file.

Subject: Dual Boot

Unless the original poster want to dual boot something other than an MS
operating system, he does not have to reformat and he definitely does
not have to purchase Partition Magic.

Simpy install Win95 in a separate directory. Do NOT install it in
c:\windows or where-ever you have installed your copy of Windows 3.1.

That's it. You now have a dual boot system. When Win95 boots you will
see "Loading windows 95" in plain text - before the opening graphic
screen. You have about a 2 second window here. Press F8. You will get a
boot menu. Scroll down to "Previous version of DOS" and you will boot
into your old DOS (6.x probably). You can now run win from the DOS

One gotcha - back up your DOS system files (but you don't have to worry
about your Windows system files): your autoexec.bat, config.sys, and any
batch files called by autoexec.bat.

The Win95 setup program may lobotomize your autoexec and associated
batch files. Simpy boot into your previous DOS version and restore your
DOS autoexec.bat and config.sys. Win95 will shuffle the different
versions of this file at boot time.

Date: Thu, 5 Dec 1996 17:10:25 -0500

The following is a discussion about running classic DOS and WIndows 3.x AND

A really good idea if you're willing to devote the disk space ( costs an
extra 16 MB or so ) is to install Windows 95 to a separate directory such
as c:\WIN95

Do a custom install and specify the directory to install to.

The advantages to this would be the possibility to boot to prior dos for
the speed and simplicity of the earlier system.

It is important to realize that Windows 95 does not need or want any
config.sys or autoexec.bat. All card and socket services and power
management are built in. So, when you DON'T install 95 over prior DOS, it
takes your config.sys and autoexec.bat and msdos.sys and renames them
config.w40, autoexec.w40 and msdos.w40. Hold that thought for a second.

After you boot with 95 installed, press F8 when it says "Now starting
Windows 95" and choose "Command prompt only"

 - ed. note: command prompt is NOT previous DOS version

type in the following: 
attrib -s -h -r msdos.sys

edit msdos.sys
add (after BootMulti=1) "BootMenu=1"
(the quotes are for reference only)

ALT F X Y to close and save
attrib +s +h +r msdos.sys

if you want, you can do this also:
ren config.sys config.16b or config.bak or whatever
ren autoexec.bat autoexec.16b or autoexec.bak or whatever

NOTE: you will have actually renamed the config.sys and autoexec.bat that
WIN95 is using- this is good because you don't want any real-mode drivers
gunking up 95

At this point you will be given a menu at boot time to boot to prior dos
6.2x or Win95.

Notice that there are files called config.w40 and msdos.w40 and
on the fly as you choose "boot to prior DOS"

These are your original files, and will be renamed *.w40 if you boot back
to 95 automatically.

They should contain card and socket services, including cs_apm.exe in
config and power.exe in autoexec. When you boot to prior DOS you can

At this point prior DOS will be the same as when the Aero was shipped, and
you'll have a clean Windows 95 without 16 bit drivers confusing the system
and taking up valuable RAM.

Some people will say you should have himem.sys and emm386.exe even in
Win95, but I think 95 does a good job of memory management. It's up to you.

Go mess up your computers and I don't want any complaints!

But the files io.sys, msdos.sys, config.sys, autoexec.bat, and 
change with a .dos for old dos and w40 for the new win95 (under dos 6X.)!

Win95 does load himem.sys automatically however it does not load emm386.exe 
and we can make more room for windows 95 and other.

Win97 NOTE: Under windows97 things on an Aero change there are no more start

There is a lot of changes in the power management (instead of just battery,

Recently, I deleted and rebuilt my Windows95 partition. I have decided to
tell you all the story in the hope that it may help some of you (and make
some others laugh).

I have two partitions on my HD. One is the F10 Diagnostics partition
from Compaq which I installed from my original disks when I got my Aero
4/25. I purchased mine used from someone in New York (If you are out there,
thank you) who had taken the precaution of deleting everything and
reinstalling the original software, but must have forgotten about the F10

My other partition is running Win95. I have been running 95 ever
since I put in a new 540MB HD and upgraded to the Southland Micro 16MB
memory module (for a total of 20MB RAM), but there were several problems.
Most of them due to my fiddling with the Registry, but some due to the
install since it was slightly bootlegged. My floppy never did hotplug
correctly, and power management always seemed like a chore.

So, finally, I decided to delete my main partition and reinstall Win95. 
So, I got my own set of installation disks (that's right, all 29 of them),
FDISK'ed my partition and formatted it. So the steps I followed, in order,

1) Update system Bios using sp1992 (This was done long ago)
2) Create Win95 rescue disk
3) Delete Primary partition using FDISK
4) Create Primary partition using FDISK
5) Boot from floppy using Win95 rescue disk
6) Format HD using "FORMAT C:\"
7) Reboot from floppy using Win95 install disk #1
8) Swap disks for hours while Win95 installs itself
9) Dial in to local ISP and search for: sp0414, sp2646, and sp2035
10) Apply softpaqs in this order: sp0414 - HD powerdown utility
                                  sp2646 - Diagnostics for Windows
                                  sp2035 - Supplemental Programs for W95
                                           (Includes power mgmt., etc.)
11) Tell you all about it.

All my PCMCIA devices (Including my 02XXX floppy) are working and
hotplugging perfectly. I still have the clock advancement problem although
it is very seldom that my Aero is suspended overnight. I usually have it
plugged in or turned off.

First: my interpretation of the answer you got from COMPAQ:
You do not neet autoexec.bat or config.sys under Windows'95, because
Win'95 is a DOS-independent operating system, while the Win 3.x is a
"shell" built over DOS.  Therefore under Win 3.x your C:\...\GUEST.EXE
will load automatically from AUTOEXEC.BAT, however under Win'95 you have
to hit F8 when you see "starting Win'95" on the screen. Then you choose
"command promt only" and from the command promt you type GUEST and hit
"Enter" button.  If the machine responds with an error message, you go
to the directory C:\...\ where the GUEST.EXE is, and you type again
GUEST <Enter> and it should work.  You will see a response like:
"THEDRIVERFORTHEDAMNEDZIPDRIVE loaded successfully", or similar, and you
will see a drive letter assigned to it, if applicable in your case.  At
the end, you type WIN and press Enter to continue loading Win'95.

Second: Now, my humble opinion on this subject. I do not have a ZIP drive,
but I do not believe you have to hit F8 and go to manually load the
drivers.  My Aero's portable (parallel port) CD-ROM loads from
AUTOEXEC.BAT and CONFIG.SYS during the normal startup of Windows'95.  I
see the loading message and the letter assigned to the CD-ROM drive
during normal Win'95 startup process (while still in the initial
DOS-like B&W screen mode) and if I REM out the two lines in AUTOEXEC.BAT
and CONFIG.SYS, I do not see those loading messages and the drive does
not work.  Remember that you do not need the two files to run Win'95 (on
my desktop I do not have those two files or even a DOS directory), but
as long as you still keep them in the root directory of the startup
disk, they will be consulted during normal loading of Win'95.
Therefore, the F8-load manually stuff is bull.

I am running Win95 OEM OSR2 on an Aero 4/33C.

My system is set up with Direct Cable Connect and my System Properties are:
    Parallel cable on LPT1
    Serial cable on COM1
    *both for direct cable connect - setup by Win95 for direct cable connect
b)Network adapters
    Dial-Up adapter
c)PCMCIA socket
    Compaq PCMCIA Controller
d)Ports (COM & LPT1)
     Communication Port (COM1) - being the "free" serial port
     ECP  Printer Port (LPT1)

My modem doesn't show up anywhere in Device Manager. It only shows up under
the Modems icon in the Control Panel. You SHOULD merely plug-in the pcmcia
modem and Win95 SHOULD see it and install it as COM2, but COM2 never shows
up in Device Manager.

I have to disagree with Pres on one account - do NOT add COM2 - it doesn't
physically exist! A pseudo COM2 is created and it's IRQ and IO address 
space get mapped to the pcmcia port (and an install dialogue shows up) the 
first time you plug the modem in. You'll never see your pcmcia modem show up
in the Device Manager panel. Once Win95 installs it then you can see it in
Compaq's PC Card (PCMCIA) Properties panel whenever it's plugged in and in
the Modems icon in the Control Panel. Installalling a COM2 port will 
definitely screw up the works.

So what's the answer to your problemo? Make sure you've got the PCMCIA
Socket showing up in the Device Manager and use auto-settings. My IRQ is
9, and two IO ranges 03E0-03E1/83E0-83E1 are used. Read on.......

I'm using the last BIOS revision Compaq put out for the Aero's and a
14.4 IBM pcmcia modem. The first time I plugged it in Win95 picked it up
and installed it. It sounds like your system is not acting the way it
should(duhh). I have to agree with Pres that you'll have to go into
Modems in the control panel and reinstall it. I would suggest though
that you first try deleting any modem that's showing up, shut the
machine down, plug in your modem, start up the machine, and see if Win95
picks it up. If not, then manually install it as Pres suggested. 

Good luck - plug and play seems to be garbage most of the time. I could
tell you a story about my desktop and trying to get a Supra internal 56K
to work (4 hours !!!) but I won't (before I had Memphis installed). As
far as PnP goes it seems that the newer revisions of Win95/Memphis work
alot better - I use Memphis 1673 and NT 4.0 on my desktop and they
picked up everything in my system without exception on the first install
- a miracle indeed.

If you installed with SP2.00 then upgraded to SP2.04 you are OK it is if

If you are having problems with your Aero not suspending properly, make

Read the compaq softpaq data.  there's a bios upgrade and I think an
upgrade to the windows program additions that fix a problem by saving the
caches before suspending.

I went straight to the newest bios and newest windows files.  Have not had
any suspend problems.  There's a hibernate32 program.  There's also a 
program that can allow you to toggle between sleep and hibernate when
suspending.  I have not been able to make that work reliably.  Currently,
mine sleeps but will only hibernate when the battery is low.

Subject: Upgrade to Windows 98

     This note is to offer some quick impressions and a caution or two to
anyone considering Windows 98 for their Aero.

     Yesterday evening I installed a different hard drive in my Aero 4/33c
(first time I had the system apart).  A friend had given me an 8xx Mbyte
hard disk that already had a bootable image of Windows 98 on it, so instead
of just wiping it out I let it boot.

     The system went out and found just about everything on the Aero and
installed some drivers completely automatically.  What it installed wasn't
perfectly right and I didn't keep it for long enough to test it completely,
but some things that weren't right are:

o  Something interfered with the battery gauge -- it always came up with 5
completely white boxes, no matter whether it was on AC or battery.

o  The floppy diskette drive did not work - whether hot-plugged or present
at boot.  The controller was recognized, and it showed no conflicts but
every time I tried to access it the O/S reported "drive not ready".  I did
not take the time to try copying the Compaq driver that was supposed to
correct the problem with Windows 95.

     Rebooting was surprisingly quick -- about on par with Windows 95.  This
is only a 12 Mbyte RAM system, so that was pretty good.  Some of the speed
may have been due to the IBM hard disk being quicker than the old Quantum
250 MByte drive.

     But the biggest negative -- SIZE.  Without installing any applications,
Windows 98 took over 400 MBytes of the disk.  Yes, it already included the
Outlook Express and Internet Explorer applications, but that's still a lot.

after install.               

I've been running Win98 since the beta2 release. My advice, don't
install it on your Aero.

First of all, it WILL NOT install in anything at or below a DX33 machine
(even desktop).
Secondly, it's somewhat bloated with all the IE4 stuff.
Third, Win95b with all updated drivers is just as "good".
Fourth, Win95b runs faster on my desktop (K5-133) than Win98.
Fifth, even though it's harder to install on an Aero, OS/2 is better
suited for "low end" 486's.

   Early betas of Win98 did not make the same hardware checks during
installation. By beta 3, the Win98 installer aborted on the Aero with
a message that Windows 98 requires a FPU. (Interestingly, Microsoft
didn't remove the installation notes on the Win98 Aero floppy driver
until well after the CPU check stopped allowing Win98 beta to
install on the Aero.)

   As far as I can see, the chances of getting Windows 98 to run on
the Aero are slim. The best solution would be the mythical
AMD 486DX5-133 upgrade if it existed. Sadly, it seems Corporate
Upgrades either never managed to work out the hardware problems or
they simply desided the market wasn't there for an expensive upgrade
for the Aero.                                                         

   The most viable alternative might be to pull the harddrive out
of the Aero, install it in a desktop machine, and install Win98
there. Then, wipe all the System Devices and a number of other
devices from Device Manager and drop things like video down to
compatible low levels. Then pull the drive back out of the
desktop and reinstall it in the Aero. You'd want the necessary
parts of the Win98 install CD in an Option directory or
something like that. Hopefully, Win98 would boot and detect
the devices on the Aero. It would be basically the same
procedure as a motherboard upgrade on a desktop machine. It
might even work if the Win98 installer is the only software
that checks CPU requirements.      

   The power management in Win98 does seem to work pretty well.
Of course, it really doesn't seem that much different from late
versions of Win95 OSR2, so I'm not sure the upgrade to Win98 is
worth it just for that.

   I don't know about PC-Card services, since I only run Win98
on a couple desktop machines without PC-Card sockets. Maybe
the upgrade would have some advantages there.

   The slowest machine on which I am running Windows 98 right
now is a AMD 486DX5-133 desktop with 20MB of RAM. It's
horribly slow, though FAT32 and a lack of RAM may have
something to do with it. My wife doesn't mind too much, but I
can't stand using that machine. I can't imagine how slow
Windows 98 would be on the Aero, and I think that might
be staying something since I happily ran Windows 95 on a
386DX-40 with 8MB of RAM for about a year.

   I would recommend finding a late version of Win95 OSR2 and
installing that on the Aero instead of Win98, but that is, of
course, only my opinion. If anyone is determined enough to       
get the final version of Win98 installed on the Aero, I'd
love to hear about it.

Good luck.

I have been told that the beta version of Win97 and the aero work very
well together. There is also the added bonus in the fact that NT and Win97
use the same device drivers and the power management has been enhanced. I
have also heard that Win98 is a processor pig and runs even slower than

Unfortunately, the commercial release of Win98 will not allow an install
on the Aero because it checks the processors and the aero is only a 25 MHz

this check by installing onto a different machine and then either coping
an image to the aero or physically relocating the drive to the aero.

I installed the patch before I put in my 16MB module, so it doesn't
help with linux, exactly; it's still better to see ~16MB than 12MB,
though. The BIOS does count up 20MB in the memory test phase, though,
which is what I've imagined that will correct.

I've seen a lot of BIOS issues where linux won't recognize the correct
memory info; apparently, it's common for BIOSes to do "nonstandard"
things, so I've seen a lot of new-ish desktops that only report 64MB,
so linux needs the mem=256M or what have you line. It works fine with
that line, however. There was talk of a patch on the linux-kernel
mailing list to try to autodetect memory with some "newer" method, but
there was some debate as to whether this was a good thing or
not... it's possible it'd be bad for us old computer users, in fact.

Also, the book I referred to earlier was

_Linux Device Drivers_, by Alessandro Rubini, O'Reilly & assoc 1998
ISBN 1-56592-292-1

on pages 173-175, he discusses "ISA memory above 1MB" and has the code
snip below, for a hole at 15MB-16MB at kernel 2.0.29, this goes into
arch/i386/mm/init.c in mem_init:

while ( start_mem < high_memory ) {

    reservedpages++; datapages--;

There is an easy fix for this, but with a very annoying new problem: you
can add a mem=20M line to your boot, via adding 


to the appropriate place in your lilo.conf. However, this hoses your
pcmcia badly, I believe because the pcmcia controller wants memory-mapped
i/o in the <16M region. 
The symptom is a hard lock-up when a card is inserted, or when the pcmcia
stuff is started at boot time.

I do have two possible kernel hacks which may fix this, but I haven't
tried them yet (I'm thinking of waiting until the 2.2.* series stabilizes
more before trying).

One is the "BigPhysicalArea" patch, which comes in the Debian default
kernel packages. Unfortunately, this puts the reserved area where it wants
to; I don't think it's possible to request a hole where the pcmcia stuff
wants it (maybe this is OK; the ways of the pcmcia chipset are strange and
mysterious, and largely unknown to me...) 

The more promising approach is that in the O'Riley book on writing linux
device drivers, it's mentioned (with a code example) that it's possible to
mark some pages as unusable at boot time, and has code to do exactly that,
albeit with an outdated kernel. I'll probably be building an aero-specific
kernel with that in mind at some point in the not-too-distant future. When
I'm in work tomorrow, I'll try to remember to post the book's exact title
and author, and maybe the code snippet as well.

Also, in the mean time, there is also a patch floating around somewhere
that allows not-normally-usable RAM to be used as a really-fast swap
"disk." I could probably find the URL with a little effort, but if I'm
really going to spend a little effort on the problem, I might as well try
building the 2.2.3 kernel with the reserved-memory hack. Has anyone out
there in aeroland tested the 2.2.* series with the aero yet? The early
ones had some reports of APM weirdness, but the 2.2.3 release seems much
more reliable on my desktop, and I'm seeing less horror stories on the
linux-kernel mailing list since 2.2.3 as well. - M

The problem is not still solved.
I did tried different lines with LILO and with loadling but with all
them I got problems, sooner or later.
More than problems what I got was "inestability"; for example the most
"fine" line I got was with "mem=20416k" at LILO.
It works fine and you get more than 16MB of RAM being recognized but
you can expect to have "extranges behaviours" sometimesi (overall if
you get at internet).

Just try it

I think the Aero was not ready for 20MB RAM, only for 16MB maximum.
Some person mentioned it at this list, sometime ago refering a
conversation with a person from COMPAQ. In fact I think, COMPAQ never
offer to sell 16MB of RAM upgrade, only 8MB maximum.

Subject: Recommended Kernel

[A] The default slackware kernal works fine, so you should start out with that.
If you really want to optimise then just install the sources which come with
slackware and compile yourself. But it doesn't really make that much

Until you get your PCMCIA modem I wouldn't really worry about changing
anything. When you do get your modem though you don't need to touch the kernel
as all the PCMCIA stuff is implemented as loadable modules.

You will need to either compile the modules yourself or get a copy of the
binaries. Compiling the modules is pretty straight forward, but you do need the
kernel sources to compile the modules.

[A] I disagree. The stock "bare" slackware kernel has a lot of stuff that will
add to your overhead and is useless to the aero. Definitely re-compile, and use
a kernel that can support the apm patches: the patches I got required at least
1.1.78. That's the kernel I have, and it is FAR better in speed, as well as
being able to handle suspend-resume much better. The pcmcia stuff is not
important until you get a modem, as the floppy isn't supported by the driver,
and works OK if it's plugged in at boot and you don't suspend. the loadable
modules have to be attached, so you need a kernel that supports modules, which
the slackware kernels do not do as of yet.


Subject: Conserving memory

[Q] Once it's all loaded up, I want to optimize the kernel for the machine (4
meg ram for the moment). Any suggestions as to what to add/delete

[A] You almost certainly want the PCMCIA stuff and the APM patch. Other than
the obvious things, you may want to use only (say) 4 rather than the normal 8
virtual terminals.

[Q] I'm hoping that I see a significant speed improvement when I switch from
the UMSDOS filesystem to EXT2 and when I compile a smaller kernel. Does anyone
have a pointer to the Kernel sources w/ APM support? I want to set one up with
APM & IDE but no PCMCIA, as I don't use my PCMCIA slot and I need to save &

[A] You should consider to comment out starting of klogd, syslogd, lpd, update,
crond and sendmail daemons from rc.* files from /etc/rc.d/ directory (of course
only if each of them ain't mandatory to you).

Also you should consider to configure kernel to use only say 2 virtual consoles
+ the one which is allocated for X. Point is that every single process in Linux
requires 40 kB of non swapable memory. By doing all described above you will
get 440 kB more pure hard RAM! And by recompiling Slackware's kernel with
minimum options you will get ca 80 kB more! So, I'm sure you will be amazed
when you get this half megabyte of static stuff off.

I tried floppy-less Linux boot w/ RedHat & Debian & gave up.  I
succeeded with Slackware 3.4 cdrom's net.i bootdsk & pcmcia.gz
rootdsk, using loadlin to boot them from DOS.  The command line is
something like

        loadlin net.i initrd=pcmcia.gz

Oh, I forgot to mention I have a PCMCIA Ethernet card - once the
install kernel was running, I nfs mounted my desktop's cdrom drive on
/mnt & everything worked just like the cdrom was local.

Check my URL for an
all too wordy diatribe on my Linux install.  So far, when it works, it
works great.  The Aero/Linux/Apache/PERL setup is a zippy little
server of HTML & cgi-bin's.  See below, tho.

[Q] I'd like to also install Linux on my new Aero. The problem is, I don't have
a floppy drive.

[A] You would be best off by finding someone who could do the first phase of
the install on an UMSDOS system, use ZIP to make a zipfile out of it, install
the zipfile under DOS, and then try to boot a kernel with UMSDOS support off

[A] Well, the one sensible way to install Linux for DOS-machine without floppy
is to use LOADLIN command from DOS. That requires root filesystem installed to
your DOS-partition and of course kernel file, which is loaded by LOADLIN. You
can find LOADLIN from linux-sites from .../slackware/contents directory. There
should be also more detailed instructions available.

[A] It can be done (I did it) - there are at least two Linux distributions on that can be installed directly over an MS-DOS filesystem
(usually in the directory C:\linux). They take 15 to 20 MB of harddisk space
(plus any swap space you may want). Since X did not work satisfactorily for me
in 4 MB of RAM, I removed Linux - (yeah, wouldn't it be nice to have that 20MB
RAM and 700MB HD 8-).

I want to report that I have installed "Monkey Linux" on my aero 4/25.

Monkey Linux is a UMSDOS distribution that comes in 5 floppies and takes
up about 20Mb of hard disk space.  The latest version uses kernel 1.2.30.

The best part is it comes with X.

I have to change a few things to make it work on the aero:

(1) relink /dev/mouse to /dev/psaux
(2) change the 'gpm' line in /etc/rc.d/rc.local to
        gpm -t PS/2
(3) download X32VG16.tgz and relink /var/X11R6/bin/X to it
(4) change XF86Config in /etc according to Subject of the
compaq aero FAQ.

Monkey Linux can be found in the sunsite and the mirror of sunsite in
Georgia Tech.

I recently installed FreeBSD 4.3 on an aero 4/25 with 20megs.
I put the FreeBSD CDROM in a desktop running FreeBSD with a network card.
After booting from the two floppies the install prompted me to remove the
pcmcia floppy and insert the pcmcia network card.
I have used the ftp and nfs methods to install and both worked well.
The install went very smooth.
I also have installed via the parallel port (laplink). Also smooth but 

[C] from: Gregory Bonar
Date: April 2001

Installing FreeBSD 4.2 on my Aero was very easy.

I created the two boot floppies and booted with my ethernet card already
plugged in. I had the install CDROM on another machine on my network, but
it is equally easy to ftp the files from any of the mirrors on the net. In
that case all that is required are the two boot floppies.

I followed the standard simple install procedures and ended up with a very
responsive unit on my 4/25 with 20MB RAM. I run emacs under X with no
problems. I used 340MB for the OS, 30MB for swap. There is an option for a
minimal install that I experimented with and it was less than 100MB. (No X).

This not a special-for-laptops install or a 'stripped down' version. It is
identical to what I run on my desktop. 

Adding a new app is as easy as typing 'make' and then 'make install'. If the
package is not on your hard drive, FreeBSD automatically tries to get it off
the net, plus any dependencies.

Linux is great - I used to use it. But I find FreeBSD to be much easier to
install and maintain. just my two cents.

Subject: Can I run OS/2 on the Aero?

There appear to be problems with Installing OS/2 and it recognizing the PCMCIA
floppy drive. Most users get to disk 7 of the installation before they have
problems. This is the point that OS/2 starts conversing with the interrupts
directly. At the present time, Compaq has no fix for this problem, and IBM does
not either.

[Q] Is anybody other than me running OS/2 on their Aero on a regular basis? At
the moment the only reasons I switch back to DOS are to copy things OFF
floppies or to use winlink. To that extent, I have found a way to access the
floppy perfectly under OS/2 ... is anybody interested?

Those who are interested should read on...


Subject: OS/2 Installation Problems

Here's a summary of problems with installing Warp: (and some answers from
someone else):

     Warp does not support the Aero's PCMCIA adapter. They may have released a
     patch, but I'm not aware of it. This means that if you try to do the
     standard install, after about disk 6 Warp will reboot the system and try
     to do the rest of the install from inside Warp after booting off the hard
     drive. Since Warp only recognizes the floppy if you boot OS/2 from the
     floppy drive, this won't work (and any floppy access will hang the Aero).
     I found out about response file installation -- write a response file to
     automate the install process, so that you don't reboot the Aero, but
     install everything off the floppies in one shot. The problems with this
     were: (a) The response file processor is buggy. When it prompts you to
     insert a particular floppy, it may develop amnesia and not remember the
     name of the floppy, so then you have to play Russian roulette with the
     floppy disks. (b) Apparently, printer drivers do not get installed. What
     you then have to do is boot OS/2 from floppy (after creating a special
     boot disk that puts you directly into the OS/2 command line) and then
     extract the printer drivers en masse from one of the Warp floppies onto a
     subdirectory on your hard drive. When you go to create a printer object on
     the PM desktop, you can opt to get a printer driver from a hard disk

     [A] I never developed a problem with installing from response files, but
     from memory I was actually using images I copied to it to the hard disk. I
     do remember that printers for me got installed properly; you just have to
     put them into the response file properly. There's a separate list of
     printer drivers in another file that you have to find the index for (so it
     knows which one), then you just put that next to the port in the response

     [A] Hmmm... I remember that I specified the correct bit in the response
     file to install the printer driver(s), but apparently it didn't work
     correctly. sigh It's just a screwy business. Anyway, by extracting all the
     printer drivers into a temp directory on my hard drive, I had the ability
     to change printer drivers at will without worrying about floppies.
      After I had gone through all this crap, I was left with two problems: (a)
     The floppy disk was still inaccessible from Warp. (b) I could not print.
     An IBM tech support guru told me that Warp defaults to using polling in
     its printer driver instead of interrupt driven printing, because some
     sound card owners had complained that previous versions of OS/2 wouldn't
     allow them to share an interrupt between their sound card and the parallel
     port. There is a way to go into the config.sys file and set a certain
     option such that the printer / parallel port driver uses interrupt driven
     I/O. Apparently, you have to do this if you want to do printing on the
     Aero, but I'm not sure if that even works because of the Aero's funky

     [A]I have no problems printing, but I only use serial (all my printers I
     have accessible have computers attached to the parallel ports, and the
     others don't have centronics ports).

     To change to interrupt IO you change a line to: device=print01.sys /irq
     (It's in the command reference book). The serial port's fine for printing,
     but I don't know about the printer port.

     [A] Yup, saw that trick in OS/2 magazine. Apparently, a lot of users were
     having problems with the polling printer I/O --- the timing is very
     sensitive, and often won't work with your particular setup. The interrupt
     driven I/O seems to solve the problem for most Warp users, so this
     probably would have worked for the Aero.

After I ran into the printing problem, I gave up and returned Warp for a
refund. It just wasn't worth the aggravation.


Subject: OS/2 Warp in 4MB RAM?

4 megs of RAM is barely acceptable for running Warp on a notebook computer. I'd
say don't bother even trying unless you have 8 megs or more.

[A] OS/2 requires 4 megs to boot, but to really use it you need 8. Because the
aero has a very slow hard disk, it will still seem sluggish in 8 ... but
there's lots of things you can do to speed it up when you're at the 8 meg mark.
My bit of advice: Don't install TCP/IP on the aero - it takes up about a meg of
memory :-( and keep your swapfile as large as you can handle - otherwise it'll
get fragmented when it increases its size.

[A] I dunno... I was able to do some stuff in 4 megs. Like, for instance, run
Mahjongg solitaire and a couple other doo-dads. :-) Oh, and the terminal
program worked just fine on my Aero. (Nobody can beat serial I/O under OS/2.)
But IBM Works was dog slow.

Warp is great, but it really needs a bigger machine to run on. Maybe if I get
an 8-meg upgrade for my Aero, I'll reconsider making my Aero an OS/2-only
machine. Now that I know much more...

[A] IBM Works ... the trick is to deregister the WPS objects, as the
registering of the DLL's (with SOM 1.0) with the WPS takes up a reasonable
amount of memory (so others have said ... my testing shows that those DLLs had
nothing allocated to them in physical memory, it was all swapped out). Anyway,
I have IBM Works installed but I have deregistered the objects.

If you want a word processor that runs really well on the Aero try ClearLook -
that's what I use for all of my lecture notes, and it's great! Describe would
probably be just as fast on an 8mb machine, but you could probably get away
with CL with only 4MB. Mind you, there are other things about describe that I
won't go into detail about, suffice to say that if somebody has an archive of
comp.os.os2.apps there is a rather large argument on there about it :-)

I couldn't stand running OS/2 in 4MB, but it's possible ... 8MB is OK, I can
live with it, upgrade to 12 or 20 and you'll never look back :-) Unfortunately
I don't have the money at the moment.


Subject: Aero floppy under Warp?

[Q] I think someone on the Aero list has figured out how to get the floppy disk
access to work under Warp. I don't remember the details.

[A] I did ... by booting DOS 6.21 under OS/2. But I started farquing around
with a device driver called 'reserve.sys' which seems to tell OS/2 to NOT use
specific areas of memory. Sounded great - possibly OS/2 using D000-DFFF was
what was causing the floppy to die; unfortunately I couldn't get reserve.sys to
work (there's no documentation), and when I removed it it killed my setup so
that my 'DOS w/ floppy' wasn't working anymore!!! I'm going to retry getting it
to work again when I get the time (sigh) ... then it will eventually go on my
web page (sigh)


Subject: PCMCIA supported under OS/2?

Check out:"" for the
official word on the subject. 

[A] I have not tested to run Warp (and it's not officially supported) but there
is a Rompaq to be able to install it and there is also VLSI PCMCIA drivers
available from IBM (both for 2.11 and Warp). Take a look at It says it's for Elite but
as I understand it the important thing is that it is for VLSI.

[A] I'm using Warp with the "Compaq Concerta" pcmcia drivers. It seems to work
but my understanding is that the Concerta uses the Cirrus chip, and the Aero
and Elite both use the VLSI chip.

[A] If anybody is interested ... I know some people are (there must be! grin)
the URL contains: - A version of the BIOS that allows OS/2 to access the floppy
     drive (if it's inserted at bootup) - A socket services driver for the Compaq LTE that uses the
     same chipset as the Aero, and will allow you to use PCMCIA cards with full
     plug and play support under OS/2

Unfortunately if you install both the floppy drive driver (ibm1flpy.add) and
the socket services driver (ssvlsi.sys) at the same time, the socket services
driver clobbers the floppy driver and you can't access the floppy drive. At
least we now have the option of using the floppy drive and the PCMCIA port now!

NB: *.sys basedev's are loaded before *.add basedevs, I tried renaming
ibm1flpy.add to ibm1flpy.sys and loading it before the socket services driver
and it still clobbered it.

I haven't tested the PCMCIA port, because I don't have any supported PCMCIA
devices other than my network card (Accton - if anybody knows of OS/2 drivers
then please tell me!) and my floppy card; but both are noted as being
inserted/removed and the OEM id's are displayed, so I assume that if you have a
standard PCMCIA modem or other device it will work; check the above URL for
drivers for SCSI & other widgets ...


Subject: 3.4 Original Compaq Software Disks

[Q] I need to get a set of the software disks for the Aero 4/25. I called
Compaq and they said it would cost $40. Since I bought the software with the
machine how can they justify this?

[A] The cost is supposed to cover costs of media, labels, delivery and handling
as well as any documentation they provide with the diskettes. I also understand
4/25 and the 4/33 and the 4/33c's with differing size hard drives allow you
different software bundles.
