UnixWare Frequently Asked Questions List (Miscellaneous Troubleshooting )

For more information about the files which compose the total UnixWare FAQ,
see the "FAQ Overview" file posted regularly on the Internet newsgroup
comp.unix.unixware.misc.

INTRODUCTION

The purpose of this document is to provide miscellaneous hints and
troubleshooting tips for UnixWare 2.x, for information that does not seem to
fit elsewhere in the FAQs.

If you have free UnixWare 2.1.2 also see the URL
http://www.freebird.org/freeUW.html first.

Some of the installation information is extracted from the UnixWare 2
Installation Handbook - please consult that for further information. For
information on invoking the DCU - see the Autoconfiguration FAQ. Much
information has been gathered from the netnews, some from the World Wide Web
Technical support databases, see the acknowledgements section.

Its maintainer is Andrew Josey (andrew(a)tamarix.demon.co.uk). Suggestions
and contributions welcome.

----------------------------------------------------------------------------

Subject: T0) How do i find out hardware compatibility, ie. does UnixWare support
  my hardware?

SCO has a set of Web pages containing hardware compatibility for
all of SCO's server products.  Certified hardware for UnixWare 2 has been
merged into those pages which can be found at http://www.sco.com/Third/hch.

The freebird project has a hardware compatibility register, where
UnixWare users can register working hardware configurations.
See http://www.freebird.org/hwcompat.html.

Subject: T1) How do i find out whether  UnixWare supports my Host Bus
        Adapter (hba)

UnixWare2 supports a selection of HBA's on the boot disk
and a separate HBA disk. This section describes the support
for UnixWare 2.01 and UnixWare 2.02/2.03 (it would be helpful
if someone suggested how to update this section for 2.1 -mod)

The UnixWare 2.03 HBA diskette is available from:
ftp.sco.com:/UW20, or ftp.freebird.org:/unixware/Patches2

Due to problems with the 2.03 README file, the changes in 2.03
are not fully described here but the 2.02 HBA set is, one change
that is known is the addition of support IDE CDROM support (see
later in this Install section).

Section A: UnixWare 2.01 HBA Support (see later for 2.02 HBA)

Some 2.x drivers will automatically detect the interrupt, I/O
port, memory address and DMA channel.  When this applies to the
driver, "auto" will be listed under "Irq/IO/Mem".  Other UnixWare
2.x drivers require that you use DCU (Device Configuration
Utility) to configure the driver or set the scsi controller to
the predetermined interrupt, I/O port, and/or memory address
before installation.  Using DCU, these can all be changed after
the UnixWare installation.

1505/1515 - These cards use a variation of the 6360 chipset and
are defined by Adaptec as VERY low end cards.  They will support
DOS and Windows only.  The Installation Handbook incorrectly
lists the AHA-1505 as supported by the adss driver.  There is no
AHA-1505, only the ADA-1505.

**      Problems arise in a some cases when scsi chipsets have been
placed directly on the motherboard or on a 3rd party controller.
Often the controller is not given the full functionality the
chipset was intended to  have.

***     The adsa driver will not auto configure with the Adaptec
2840/42 controller.  The fundamental problem is that the VLB
(Vesa Local Bus) can't tell the system what kind of slots or
cards they have.  As it happens, the adsa driver (for the Adaptec
7770 chip) is mainly targeted for the 2740 card, an EISA device.

        To make the adsa driver work with the 2840/42 controller,
enter the DCU when prompted after loading the HBA diskette.  (If
you are not installing, you will not be prompted to enter the
DCU).  Go to "Software Drivers", and "Host Bus Adapters".  Move
the cursor to the "adsa" entry (note that the AHA-2842 is not
mentioned, but this is the right driver nevertheless).  Hit
for "new".  Change the ITYPE field from 4 to 3.  Change the
interrupt number to match the value the card is set to.  Hit
 to save and exit, and then exit out from the DCU, saving
your changes.

        This procedure can be repeated if a second 284x is to be used
during the installation.  In other words, hit  again for the
second card.

Section B: : HBA202 - UnixWare 2.02/2.03 HBA drivers

*  Features

The following HBAs are new or enhanced for 2.02/2.03:

-  Future Domain HBA Driver fdeb

The fdeb driver provided by this package has enhanced
direct  access to the SCSI peripherals (pass-thru) and extended
read/write support.

The default UnixWare configuration is interrupt 5 and
memory address CA000-CBFFF.

-  Future Domain HBA Driver fdsb

Enhanced direct access to the SCSI peripherals (pass-thru)
and extended read/write support are provide in fdsb in
this package. Also, support for the Future Domain PNP-1630
adapter has been added to the driver.

The default UnixWare configuration is interrupt 11 and I/O
address 140-14F.

- Western Digital HBA Driver wd7000

Enhanced direct access (pass-thru) ioctl support is
available in this release of the driver.

The default UnixWare configuration is interrupt 15, I/O
address 350-357, and memory address CE000-CFFFF.

-  Media Vision HBA Driver zl5380

Support for the Media Vision Pro Audio Spectrum 16 adapter
is provided in the this package. Note that this support is
SCSI only, and that support for audio on this adapter
is not provided.

The default UnixWare configuration is interrupt 10 and I/O
address 388-38B. Interrupt and I/O settings should be
verified using the Quick Start program provided with the
controller (runs under DOS).

-  New Advanced Micro Devices HBA driver amd

The new amd HBA driver is provided in this update.  This
driver supports the following adapters:

            Am53C974 PCscsi
            Am79C974 PCnet-scsi.

Tagged command queuing is supported, and the UnixWare
auto- configuration utility is responsible for configuring the
adapter for use with the system.

-  Bus Logic HBA Driver blc

blc has been modified to support the following adapters:

            BT-956C
            BT-956CD
            BT-7942 (RAID)

These adapters and the blc driver support "WIDE SCSI,"
tagged command queuing (if enabled), and  hot insert.  The
UnixWare auto-configuration utility is responsible for
configuring the adapter for use with the system.

-  Symbios Logic HBA driver c8xx

The 2.02/2.03 HBA package provides the Symbios Logic HBA c8xx.
This driver supports the following PCI to SCSI adapters
and controllers:

            Symbios Logic 8100S (adapter)
            Symbios Logic 8251S (adapter)
            Symbios Logic 53c810 (controller)
            Symbios Logic 53c820 (controller)
            Symbios Logic 53c825 (controller)
            Symbios Logic 53c815 (controller)

Tagged command queuing, WIDE SCSI and hot insert are supported.

The UnixWare auto-configuration utility is responsible for
configuring the adapter for use with the system. The
driver will support the Symbios Logic (NCR Microelectronics)
53c8xx family. The driver will NOT load on COMPAQ Computer
Corporation's 53c8xx host adapters in COMPAQ machines. The
user must use the update cpqsc driver for the 53c8xx in
COMPAQ machines.

-  DPT HBA driver dpt

The dpt driver has been enhanced to support WIDE SCSI, hot
insertion/removal and EATA direct access to the SCSI peripherals
(pass-thru). The Storage Manager utility is   supplied by DPT directly.
You can monitor the the controller and target devices via the Storage
Manager, in addition to performing diagnostic and maintenance tasks.
Tagged command queuing is still supported by the controller
firmware without driver intervention.

EISA and PCI versions of the DPT controllers are completely
auto-configured and require no special configuration. ISA
versions of the DPT controllers need to be configured as
follows: I/O Address - 170 (also called "secondary"),
Interrupt 15 and the controller BIOS can be configured at
any non-conflicting address.

-  The New Adaptec HBA Driver adsl

adsl supports the following adapters:

            AHA-2940
            AHA-2940W
            AHA-3940
            AHA-3944
            AIC-7870
            AIC-7850

WIDE SCSI peripherals may be used with the AHA-2940W
adapter.

The UnixWare auto-configuration utility is responsible for
configuring the adapter for use with the        system.

-  COMPAQ HBA Driver ida

ida has been modified as follows:

          - support for more than seven disks
          - support for WIDE SCSI
          - corrected interaction with CIM agents
          - corrected operation of ida controllers with IDE
            compatible interfaces

The UnixWare auto-configuration utility is responsible for
configuring the adapter for use with the        system.

-  COMPAQ cpqsc HBA Driver cpqsc

The COMPAQ cpqsc HBA driver is updated in this release.  The
driver supports the following:

COMPAQ Integrated 32-bit
COMPAQ Integrated 32-bit Fast-SCSI-2 (CPQ4410)
COMPAQ 32-bit Fast-SCSI-2 (CPQ4411)
COMPAQ Integrated 32-bit Fast-SCSI-2/E (CPQ4430)
COMPAQ 32-bit Fast-SCSI-2/E (CPQ4431)
COMPAQ Integrated 32-bit Fast-SCSI-2/P (Symbios Logic 53C810)
COMPAQ 32-bit Fast-SCSI-2/P (Symbios Logic 53C825)

Support for WIDE  SCSI peripherals, tagged command queuing,
and hot insertion has been added.

The driver will support COMPAQS Fast-SCSI-2 family of
controllers.  The driver  will NOT support the Symbios
Logic (NCR Microelectronics) c8xx host adapters.

Subject: T1.1) Installation fails intermittently on my Adaptec 1542B, what
  should I do?

Check the jumpers for the speed setting. Some cards will fail to install
when the DMA transfer rate is set too high, say 8MB/sec. Change
this to 5MB/sec and retry, this is typically removing jumpers 12 and 13
from block J5.

Subject: T1.2) My system automatically detects two Adaptec 2940 PCI SCSI
controllers when I only have one, what should I do?

This is a well-known problem that affects some, but not all PCI
motherboards. Obtain tf2069.tar (note that some of
the other tf2069 files on the ftp site are corrupt, so get this
larger file) to extract a new boot floppy for the
AS as well as the PE.  (NB, you still need the original install
floppy 1 in order to license your installation -- see release notes of
ptf2069 for more detail.)

Subject: T1.3) The system does not recognise my Adaptec 1542CP,
   what should I do?

I ordered an Adaptec 1542CF and got (instead) 1542CP.  I have tried
a first time installation of Unixware and can't succeed.  DCU shows
one device as UNKNOWN at the bottom of the list with parameters which
can't be changed (as far as I can tell), and don't appear to match
my board.  Can I use the Adaptec 1542CP (the "P" is for plug and play)?

The solution is to disable the Plug & Play feature in the
Adaptec 1542CP's BIOS. Use IRQ 11 & 330 as the port address (as noted
above for the 1542C).

Subject: T2) What to do if the Booting UnixWare Message is not displayed

Check whether the boot disk drive contains a diskette. If so,
remove the diskette and reboot your system. Otherwise, you may have a
system hardware problem. See the documentation provided with your
hardware. Many add-on devices and cards come with configuration
utilities. Check all the  connections and run the configuration
utilities.

Subject: T3) What to do if the system Panics or Resets While Booting from
    the Install Diskette - for example on an IBM Thinkpad 755CX

Problem. After booting your system with the Install Diskette, the UnixWare
logo screen is displayed and then the system either displays a panic message or
resets (the system FIRMWARE messages are displayed again).

You can either try an alternate boot diskette from
ftp.sco.com:/UW20/tf2069.tar
This is known to work when installing on an IBM Thinkpad 755CX.

If you still have a problem read on.

This problem is typically the result of not running a hardware
configuration program, such as the ECU or the CMOS setup program, before
installing UnixWare. To fix the problem, run all machine and peripheral
hardware setup programs provided by your hardware vendor and verify that
your hardware is correctly configured. In particular, check your memory
size/control, cache control, bus speed, and video specifications. See your
hardware documentation for details.

For example, this problem may occur if the correct amount of memory is not
configured. (To determine the amount of memory on your system, either check
your hardware documentation or CMOS settings.)

If running hardware setup programs does not solve the problem, then there
may be a memory problem. You can try to manually set the amount of memory
on your system as follows

1.      Reboot your system.

2.      When the Booting UnixWare... prompt or the logo is
displayed, press the <SpaceBar>

The interactive boot session prompt, [boot]#, is displayed.

3.      Set the MEMRANGE parameter by typing

MEMRANGE=0-640K:256,1M-nM:16896

GO

where, n is the amount of available contiguous RAM in megabytes.

4.      Continue the installation of your system until you are
asked to reboot the system.

5.      When prompted to reboot your system, invoke a UnixWare shell by
typing

<Alt>-<SysRq>-<H>

The VT0> prompt is displayed.

6.      Update the /stand/boot file by typing

echo "MEMRANGE=0-640K:256,1M-nM:16896" \

>> /stand/boot

7.      Type

<Alt>-<SysRq>-<F1>

8.      Continue the installation .

Subject: T4)Your PCI system hangs or panics during installation

Symptom: This problem will normally be seen as a system panic during the
initial boot sequence, with the following format:

Kernel Mode Address Fault on user address ...

Background: UnixWare 2.1 provides support for PCI systems which conform
to the PCI 2.1 bus specification.  The installation assumes that PCI
systems will provide support for all PCI 2.1 BIOS calls, but some
motherboards only conform to the older PCI 2.0 standard.

Solution: If you suspect that your system has this problem perform the
following procedure.

1. Press reset (or power the computer off, then on again if you do not
   have a reset button).

2. Wait for the Booting UnixWare... prompt.
   Hold the space bar down until you get the # prompt for an
   interactive boot session.

3. Hit the  key to get a fresh prompt, then type the
   following commands:

    # PCISCAN=2.0
    # go

4. If you still experience the same problem it is likely that your
   system makes non-standard (or very old standard) PCI BIOS calls.
   You could follow the above procedure, setting PCISCAN=NO instead
   of PCISCAN=2.0.
   However, this will mean that the system will not automatically
   detect PCI peripherals.  If you do this you will need to manually
   configure your PCI devices using DCU.  It is probably easier,
   safer and less time consuming to get hold of a better motherboard
   than to attempt this.

5.When prompted to reboot your system, invoke a UnixWare shell by typing

<Alt>-<SysRq>-<H>

The VT0> prompt is displayed.

6.      Update the /stand/boot file by typing

echo "PCISCAN=2.0" >> /stand/boot

7.      Type

<Alt>-<SysRq>-<F1>

8.      Continue the installation.

Subject: T5) The system hangs on a reboot.

- If your computer has a hard disk drive greater than one gigabyte and you
have an Adaptec 1542 SCSI controller with extended translation enabled,
disable the extended translation.

- If your computer already had an operating system (for example, OS/2)
before installing UnixWare, it may have a "boot code" on the hard disk
which is incompatible with UnixWare. If this is the case, UnixWare will
not boot and you may receive a message such as Cannot Load User
Driver or No Active Partition Found.

You should obtain the osbs from ftp.abs.net:/unixware/freebird/bootselector.

Subject: T6) You've installed a new kernel and it fails to boot.

You can restore the old UnixWare system as follows:

1.Press reset

2.Wait for the Booting UnixWare... prompt; then press the
 key to begin an interactive boot session.

3.When the [boot]# prompt is displayed, type

KERNEL=unix.old

go

Subject: T7)  What to do if your Resource Manager Database gets Corrupted

Problem. The system will not boot and an error message indicates that the
resource manager database, /stand/resmgr, is either corrupted or missing.

Solution. Reboot UnixWare. Press  when the Booting
UnixWare... prompt is displayed. The interactive boot session prompt,
[boot]#, is then displayed. Type

RESMGR=resmgr.sav

GO

This loads a backup copy of the resource manager database. You system should
then reboot.

When the system comes up you may want to invoke the DCU to verify that
all device  driver parameters are set correctly. A corrupted or missing
resource manager database  is normally the result of improper changes
made when adding/modifying hardware  parameters.

Subject: T8) Your machine has the Power Saver Option Enabled

Problem. Installation fails at random points after the hard disk is  set
up (or the  message WARNING: Disk Driver Request Timed Out,  Resetting
Controller is displayed after a successful installation) on  systems
with the "Power Saver" option (also referred to as "Power  Management"
or "Green PC") enabled.

Solution. Turn off the "green/energy star" power saving time outs in the
system BIOS. (Refer to the hardware manual for details.)

Subject: T9) UnixWare does not see the additional 16 MB added
 to my machine with the existing 16 MB, what should I do?

If it's an ESIA machine it's very important the the EISA config is run
correctly.
And then there is page 132 of the Installation Handbook.
        "Create a /stand/boot file with the following entry:
        MEMRANGE=0-640K:256,1M-16M:512,16M-nnM:8704
        where nn equals the actual amount of RAM memory, in megabytes.
        see boot(4)"

Subject: T10 )Is there support for  IDE/ ATAPI CD-ROM drives?

You need either hba203.tar or tf2197.tar
These can be obtained from ftp.sco.com:/UW20

tf2197.tar: 102400 bytes
TF2197 - IDE Host Bus Adapter Driver -- 11-15-95/20:12p
PTF2197 provides UnixWare 2.01 with support for the IDE HBA
driver for use with ATAPI CD-ROM devices.

The following ATAPI CD-ROMs have been tested (other drives
may or may not work):

   Mitsumi ATAPI CD-ROMs with firmware of BB03, BE01L, BB04, and BS01.
   Toshiba ATAPI CD-ROM XM-5302 with firmware of TA1095.
   Sony ATAPI CD-ROM CDU76E-S with firmware of 1.0C.

If you are installing afresh:

(1) Boot off the UW2.01 boot floppy

(2) When prompted install 2.03 HBA disk

(3) Enter DCU

        Software Drivers
        Host Bus Adaptors

        Deselect all but the ide driver

        Select F5 for new

The primary PCI IDE controller, if used,
should be configured with:

   IRQ      14
   IOStart  1F0
   IOEnd    1FF
   MemStart 10000   (THE DEFAULT VALUES)
   MemEnd   10001

        Select F5 for new

The secondary PCI IDE controller, if used, should be configured with:

   IRQ      15
   IOStart  170
   IOEnd    17F
   MemStart 0
   MemEnd   0

NOTE on MemStart and MemEnd values:
-------------------------------------
Kevin Bulgrien reports:

If you have trouble with zeroes, using "-" for both IDE drivers'
MEM Start and MEM End addresses is perfectly fine.  In fact,
given that the standard IDE controller does not usually map any
memory address, my _estimation_ is that the default values on
the DCU's new instances of ide are probably not really legitimate.
(END Note)


Go into HW Configuration again, if you have three ide controllers
switch the first to N

Then exit, save changes and apply

If you have a running system, you can pkgadd the hba diskette,
and then enter the dcu. (Before attempting this you may want to
ensure you have created your emergency boot diskettes).
If installation fails and you cannot boot the operating system,
the recovery procedure is as follows:

1.Press reset
   2.Wait for the Booting UnixWare... prompt; then press the
 key to begin an interactive boot session.

3.When the [boot]# prompt is displayed, type

KERNEL=unix.old

go

If that does not work then

Before the go add

RESMGR=resmgr.sav

This loads a backup copy of the resource manager database. Your system should
then reboot.

Kevin Bulgrien reports further experiences:
The machine:

486DX4-120, DTC-2278 VESA Bus IDE controller, 1.6GB Maxtor Master on primary
IDE channel, Mitsumi FX400 Master on secondary IDE channel, Partition 1
is bootable Novell DOS 7 and is 256 cylinders or max size for 8K clusters
under DOS; Partition 2 is 256 cylinders and is defined as an extended DOS
partition used as "D:" when booted on DOS; Partition 3 is 277 cylinders to
be used for the bootable UnixWare installation.  IDE controller/BIOS is set
to use LBA, Block Mode, and 32 bit transfers - works great on DOS.

The symptoms:

If you are installing UW 2.01 from an IDE CD-ROM on top of an existing UNIX
partition, you will not be able to do so without first deleting the UNIX
partition.  I made a mistake on an install, (or, if you will, so screwed
things up that I wanted a clean reload instead of a fixed up install), and
decided to reinstall from CD and wipe out the old installation.  No matter
what you do, the boot disk for 2.01 WILL NOT allow you to reload from CD
as long as there is a valid UNIX partition defined.

In fact, no matter what you pick at the install screen where you are given
the chance to "Proceed with the installation", or "Enter the DCU", you will
never get to the DCU to configure the ide channels.  You always proceed
directly to the options for install - which DO NOT list the CD as an
option.  This screen only comes up after a very lone wait of about 5
minutes.  Repeat, there is no way to access the DCU to configure the
IDE to allow use of the CD-ROM drive!

I tried different ways around this, ie. load order of the HBA and TF2197 HBA,
warm start, cold start, retries in case I mistyped something out of
frustration, set active partition to DOS partition, all to no avail.

The fix - yeah, right - NOT!

Delete the UNIX partition.  Seem simple?  Not so.  The DR-DOS 6 disk which
comes with UW 2.01 does not have an FDISK which allows deletion of non-DOS
partitions.  Novell DOS 7.0's FDISK does not allow this either.  I had to
find an MS-DOS boot disk with FDISK on it.  MS-DOS' FDISK does allow you to
delete non-DOS partitions.

Once the UNIX partition is deleted, installation proceeds normally.  Surely
this is a bug in the TF2197 HBA?  Does the same thing happen for the 2.03
HBA?  I will shortly be finding out.

Are there any dissenting facts concerning this work-around?  I would be
delighted to learn of a way to not have to delete the UNIX partition.

Conjecture about other results of this possible bug:

I have never successfully used the Emergency Boot disks.  To be fair, I have
not tried them more than a couple of times.  I have noticed, without reading
details, many messages about the emergency boot disks not working.  Is it
possible that the problem that causes installs to fail may cause other boot
from floppy procedures to fail?  I do not know, but would appreciate feedback
on this.

Other problems with TF2197

Upon boot, immediately following the NUC startup messages, the following
warning message appears - for me, only when TF2197 is installed:

WARNING: EXTRA BYTES OUT 55476

- or-

WARNING: EXTRA BYTES IN 36

I have not determined if there is a pattern which would let you predict
which one of the above two messages occurs upon boot up, but one of these
messages always appears.  If I were to guess, I would say that the OUT
message is a cold boot, and the IN a warm boot, but again, I have not
figured out the pattern.

These messages occur no matter which way I answer the MEM Start and
MEM End entries in the DCU - Just thought I'd mention that.

Subject: T10.1) Sony CD33A & Unix 2.01 Install

Kevin R. Bulgrien (102174.1561@compuserve.com) reports:

Please note that use of the non-SCSI Sony CD33A CD-ROM drive places restrictions
on your configuration of the CD controller:

I am using a Sun-Moon-Star controller, but I suspect that these items are also
relevant to any controller for the Sony drive.  Also note that I am relating
this information with regard to the "sony" HBA that comes on the UnixWare 2.01
HBA diskette.

As indicated by the Novell "UnixWare 2.0 Installation Handbook", but which
bears repeating, the CD will only be usable when the controller is set to
IRQ 5, I/O address 320-323, Memory addresses 0-0, and DMA 1.

You may want to continue reading if you use a Sony CD33A, and if:

1) You try to use the CD controller at alternate IRQs, DMA channels, or I/O
   addresses.

2) You have a sound card - especially older ones with hardware straps that
   are used to configure the card.

Here follows my findings on the above listed situations:

IRQ 5

a) If not set to 5, the CD may very well be detected.  However, when the
UW 2.0 install CD is checked, right before installation begins, an error will
indicate that the install CD is not in the drive, or the CD is damaged,
and unreadable.

b) Many sound cards use IRQ 5 by default.  A sound card on IRQ 5 will
effectively disable a CD controller configured with IRQ five.  The CD is
detected, but is unusable.  BE AWARE that older Sound Blaster cards, and
others, I assume, have straps that set the IRQ, BUT, you can change the
IRQ with software after DOS boots.  The result is that you may actually
use another IRQ for your sound card, but, when UnixWare boots, the DOS
configuration program is not run to set the IRQ, and the IRQ defaults to
the strapped settings - which may be different than the settings you
use all the time under DOS!

DMA 1

a) Ditto the above notes for this setting.  The controller I use will
allow no DMA (Polled Mode), or DMA 1-3.  No DMA, or DMA channels other than
1 will not prevent the CD from being detected, but will prevent the CD from
being readable.

b) Same warning goes with regard to strapping, if any, on your sound card.
If you are going to have a DOS bootable partition, and want your sound card
to be most usable with both, I believe that DMA 3 is the second best choice
for the 8-bit sound driver DMA channel.  (DMA 5 is commonly used for the 16
bit sound driver.)

I/O 320-323 (MEM START & END)

I believe, if I remember correctly, that alternate addresses cause the CD
to be undetectable - I may be wrong though.  The symptoms may
be the same as for IRQ and DMA settings.

DRQ

My controller has settings for no DRQ or DRQ 1-3.  I have not experimented
with these settings so as to be able to draw conclusions on the results of
different settings, however, I detect no problems at all when setting DRQ
1 - which seemed to match up with DMA 1?  Maybe this is a dumb
conclusion - Any comments from anyone on this?

Subject: T11) Installing Windows 95 on the same disk as a UnixWare partition
overwrites the boot loader. What can I do?

Install the  osbs boot manager, this can be obtained from
ftp.freebird.org:/unixware/freebird/bootmanager.

osbs can also let you support multiple operating systems on the
same machine, say Windows 95, Windows NT , Linux and UnixWare.
It presents a menu when booting for which one to select.

Subject: T12) Desktop tools stop working.

Critical system commands such as tfadmin, no longer execute.
This causes administration tools in the desktop to not function.

These symptoms could occur after doing a backup and restore of
system files, or after doing pkgchk -f.

TROUBLESHOOTING

To determine if the filepriv database is out of sync, as
superuser run the command:

     initprivs

CAUSE

System commands such as passwd, tfadmin, ftp, etc. rely on the
filepriv database to be correct.  If a file mentioned in the
filepriv database has been modified on the file system in any
way, including simply touching the file, and that change is not
reflected in the filepriv database, the command will not execute
or will not function properly.

One way to cause a lack of syncronization between the file
system and the filepriv database is by doing pkgchk -f, which
goes through the /var/sadm/install/contents file and compares
file attributes in the file, with those on the file system.  If
there is a discrepancy between the two, pkgchk changes the file
attributes on the file system to match the contents file.  Once
the file on the file system has been modified, the filepriv
database is now out of sync with the actual file.  This will
cause the symptoms above to occur.

Another way the filepriv database can become out of sync, is by
backing up and restoring system files.  This causes the 'last
update' time of the file to be modified on the file system, which
does not match the last update time in the filepriv database.

SOLUTION

To syncronize the filepriv database with the file system, run the
command:

     /etc/security/tools/setpriv -x

To check the filepriv database at any time, run the command:

     initprivs

Initprivs will return nothing if the filepriv database is in
sync with the file system.

Subject: T13) Desktop tools stop working when using a monochrome vga monitor

This can be caused by using a monchrome  (gray-scale) vga monitor. Checking
/tmp/xdm-errors shows some error messages. The X Server does not find
enough colours to function.

Several work-arounds exist:

(1)  Reboot the system.  When the red Novell logo appears, hit
enter to get to the interactive boot prompt.  Once there, type
"go" and hit enter.  The system will come up and will look and
function properly.

(2)  Disconnect the monitor from the VGA card during boot.  Once
the system has had time to come up, connect the monitor and it
should function correctly.

(3)  Connect a color VGA monitor for boot.  Once the system is
up, the monitor can be swapped for the monochrome and it should
function properly.

(4)  There have been reports that simply having the monitor
turned off during boot also works.  However, this could not be
reproduced on a consistent basis.

Each time the system is rebooted, one of these methods must be
used.

Subject: T14) How do I configure Mosaic to change its Home page and
    foreground/background colours?

Place your Xdefaults in $HOME/Mosaic or /usr/X/lib/app-defaults/Mosaic,
or $HOME/.Xdefaults-nodename. The desktop seems to control .Xdefaults.

Mosaic*homeDocument: http://myhome.com
Mosaic*Background: color-name-here
Mosaic*Foreground:  #000000000000

You can also set various Mosaic defaults on the command line, as in:

Mosaic -mono &   # for monochrome monitors

Mosaic -bg Green -fg White &  #  set the background colour to green and
     # the foreground text to white

Subject: T18) How to setup  UUCP over TCP/IP between two UnixWare machines

Step 1. Edit /etc/uucp/Devices and uncomment the following line

CS  - - - CS

This then uses the connection server to make connections.

Adding ",eg" to the CS string, you can use the "e" =error-free protocol instead
of the much slower traditional "g" one.  As the TCP "line" can be guaranteed
as error-free, there is no need to use the "g" protocol if both sides support
the "e" protocol:

CS,eg  - - - CS

Step 2. Edit /etc/uucp/Systems , add a line for each system you want to talk
to, for example to system raven

raven     Any CS - -,listen:10103

This entry makes "uucico" run over the TCP network.  It causes the Connection
Server to connect to the "10103" service through the "listen" service.
The "10103" service invokes uucico.

Step 3. Edit /etc/uucp/Permissions, to allow remote systems
connecting over the connection server to send and request files (note
that remote systems also need an entry in /etc/uucp/Systems).

LOGNAME=nuucp SENDFILES=yes REQUEST=yes

Step 4.  When the above steps are completed on both UnixWare machines, use
the following command to make sure that you can UUCP to the remote system.
You should get "Conversation Complete: Status SUCCEEDED" at the end of the
uutry output.  If not, something is not configured properly, or the remote
machine is not a UnixWare machine and you should use the other
configuration method outlined below to establish UUCP communication.

/usr/lib/uucp/uutry -r  remote-sys-name

Subject: T19) How to setup  UUCP over TCP/IP between UnixWare  and
   another O/S running UUCP.

By conventions most machines support Uucp over TCP on port 540.

Step 1. Allow incoming connections on uucp port 540.

To perform these steps, you should be logged into the desktop as
the system owner and should have an xterm open where you have
used the 'su' command to become root.

uucp    stream  tcp     nowait  nuucp   /usr/lib/uucp/uucico    uucico

This sets up a listener through the inetd port monitor to listen
for uucp and run uucico as user nuucp.

1.1.2   Stop and start the inetd service by issuing the following
commands:

sacadm -k -p inetd

sacadm -s -p inetd

1.1.3   Test the new listener by telnetting to port 540 as
follows:
telnet localhost 540

You should get a prompt back that says, "Shere=FOO" where "FOO" is the
node name of your UnixWare machine.  You can just close this window,
open a new window and 'su' to root again.  Or, if you wait a few moments
the connection will just timeout and give you a '#' prompt back.

The 'Shere' line that is displayed is uucp on your machine saying,
"Here I am!  Send me some uucp commands."  If you don't get the "Shere"
then something is set up incorrectly.

Step 2.  Setup the outgoing uucp connection using the Connection Server.

In /etc/uucp/Devices put

CS  - - - CS

In /etc/uucp/Systems  put

node Any CS - node.domain.name,uucp in:--in: Logname word: passwd

Where node is the UUCP name node.domain.name is a full domain name that
TCP/IP can see uucp is the service in /etc/inet/services (=540)
Logname is the login name. Passwd is the password.

Plus usual Permissions entries.

Step 3. Test the connection.

Assuming that the remote system is ready to accept uucp communication
from this UnixWare machine on port 540, we should get "Conversation
Complete: Status SUCCEEDED" at the end of a uutry.  Now uutry the system
by issuing the following command:

/usr/lib/uucp/uutry -r   name

Where  "name" is the name of the remote system as defined in the
/etc/uucp/Systems file.

If it doesn't work, something isn't configured correctly.  Make sure
that the remote system is ready to receive uucp communication.  This
often requires an entry in the remote system's /etc/uucp/Systems or
/etc/uucp/Systems.tcp file for your local system.  (In other words, put
the UnixWare's system name in the remote machines Systems file(s).)

Subject: T20) How do I get my serial communications working?

see  http://www.freebird.org/hints/comms/serial-comms.

Subject: T21) In UW1.x in order to use the 16550 UART chips in my serial card,
    I needed to use the asyhp driver. Is this still necessary in UW2?

In UnixWare 2 you should NOT use the 'asyhp' driver.  All functionality
of the 1.x asyhp driver has been rolled into the new 'asyc' driver so
there is no need to modify the default serial driver in UnixWare 2.
This is discussed in the man pages for both asyc and asyhp.

Subject: T22) How can I debug outgoing modem connections?

Outgoing calls are managed by the connection server [cs(1M)].  Both
cu(1), uucp(1), and ppp(1) use the connection server to dial.

When you click on either 'dial' from the GUI device setup window or
double click on a system icon, you are running 'cu' and can use this
technique to debug your problem.

Many every day problems (such as the remote line being busy) can
be debugged using the connection server debug mode.

To activate cs debug mode, enter the following at the command
line as root:

   # ps -eaf | grep cs
   # kill -9 (the process id of the /usr/sbin/cs process)
   # /usr/sbin/cs -d

This will start a log in /var/adm/log/cs.debug.

A good debugging technique is to have the 'cs -d' running and in a
separate terminal window, enter 'tail -f /var/adm/log/cs.debug'.  Then,
in a separate window do your cu or uucp request.

You'll see what is being sent (e.g. atdt5551212) and what is being
expected (e.g.  CONNECT) as well as some technical details about which
line is being selected and so forth.

At some point you may want to turn cs debug mode off to save space.

To do this, kill the currently running cs process as shown above
and restart cs using '/usr/sbin/cs' without the -d option.
Alternatively, you could continue to run cs in debug mode and
write a cron(1M) daemon that keeps the size of the
/var/adm/log/cs.debug file reasonable.

Subject: T23) How can I quickly setup outgoing uucp?

A tar file containing key /etc/uucp configuration files can be found on
the freebird archive (ftp.freebird.org:
/unixware/freebird/hints/Mail/uucp.quick.tar.Z) . This will setup a
hayes compatible modem on COM1 for outgoing uucp only.  See the README
file included for details.

Subject: T24) How can I access a Comms port from DOS running under UnixWare?

From a shell prompt on a virtual console try:

                dos +acom2 (or +acom1)

or under X windows, from a shell prompt try:

                dos +acom2 +x (or +acom1)

from you desktop, in the applications folder, click mouse button 3 on
the DOS icon, and then select Options, then select a COM port.  From
there you can invoke this options for a single session by choosing
Start, or you can have the current options tied to that icon by choosing
Apply.

All of the above will fail if another program (like the port manager,
connection manager, uucp or cu) has the port locked.

Subject: T27) Does UnixWare-x.x support Card and Socket Services ?

   No.

Subject: T27.1) Does UnixWare support PCMCIA?

   Yes and No. Anything that is supported or is known to be working only works
   with notebooks with Intel-compatible PCMCIA controllers (ie. Intel, Cirrus,
   Vadem, VSLI, etc...). See 'What PCMCIA cards work with UnixWare'

   Check with your notebook's vendor before making a purchase, ie.
   1/ What PCMCIA controller chip reside on the notebook ?
   2/ Is the PCMCIA controller chip Intel-compatible ?
   Note that some sales(wo)men just don't know what you are talking about.
   Double make sure that you can return the notebook.

          Ethernet/Modem/Sound

        - Accton Technology - EN2212/EN2216 (http://www.accton.com)
          Ethernet only
          Note: the enabler was written by Lynsoft. It uses native UnixWare
                ne2k/NE2000 driver. This enabler is not supported by the vendor

                Compatibility Handbook (on the web site) as 'Reported' to work
                However, I failed to get it to work. The transmogrified
                NE2000 driver in UnixWare-2.1 has changed in such a way that
                none of these enablers could talk to the driver.

   in your 'SCO Unixware - Installation Handbook'

Subject: T27.4) How do I get my 3Com 3c589x or the Xircom ethernet card working ?

   Just like when you install your ISA ethernet card...

   1/ 3Com 3c589x: insert the card into the socket before installing
      UnixWare-2.1. Select the appropriate driver when prompted.  Or
      run 'niccfg' (available when you install the 'nics' package),
      and select the appropriate driver when prompted.

   2/ Not sure about the Xircom. Should be similar but I just never tried.

Subject: T27.5)  Are there any pitfalls when installing UnixWare  2.x on a
   laptop with PCMCIA support?

(Martin Sohnius writes)

Yes, and yes.  :-)

Buy an Ositech Trumpcard "Jack of Diamonds" combined modem/ethernet card.
It's not cheap, but know to be the only one which works with UnixWare.  It
comes with a UnixWare driver in the box (which installs like a dream), and
according to the very good instructions in the README files, you can even
use it for a network install.

Don't install the nics package; the Ositech driver takes its place later.

You other question:  pitfalls.  It depends on the Thinkpad model.  Some of
them (notably the 755CX which I have, but also Pentium-upgraded other
models) fall over with the Machine Check Exception panic after the first
boot floppy.  Download the tf2069.tar file from the ftp server (*not* the
tf2069as.tar file -- that seems to be corrupt!) and create a new boot floppy
from it.  Follow the instructions in the *.txt file as to the special boot
parameter

        CR4_MCE=NO

You cannot use a CD-ROM in the Thinkpad proper (it's an IDE-ATAPI).  So,
unless you want to network install with your Ositech or with the "slip
install" in the USLE archive (takes forever!), you need a docking station
with a SCSI CD-ROM drive.  The SCSI adapter in "Dock 1" is a Future Domain
(driver name fdeb) and is factory set to IRQ 11.  Since UnixWare's default
is IRQ 5 for the fdeb driver, you must change it in the DCU (or set the IRQ
to 5 in the hardware).

Please, totally ignore the TID in the NetWire archive on 755E and docking
stations!  It's garbage.

Subject: T27.6)  What laptop video chipsets does UnixWare support?

UnixWare has native drivers for:

1/ WD90C24xx

Subject: T29)  When installing the 2.02 update, an error appearead about
a bad entry on the contents file - how can this be fixed?

When trying to install the 2.02 update on to my 2.01AS system,
partway through the following error appeared:

 bad entry read from contents file :     - problem: unknown ftype
 UX:pkginstall: ERROR: unable to merge package and system information

The install halted after the error.  I've also noticed that on system
startup, the console shows an error message somewhat similar, about a
problem merging contents or something.  What's the cause of the
problem?

The problem is in the file /var/sadm/install/contents.  Usually the very first
line is badly corrupt (no idea what combo of circumstances causes this,
though).  Delete that first line.

Subject: T30) How do I install the *.pkg.tar.Z files from the freebird archive?

        xxxx.pkg.tar.Z     A compressed tar archive of a binary in
                           pkgadd format

Where a file is suffixed with .gz this means that the GNU Zip
file compression utility has been used - to uncompress in this
case use gunzip.

The ".pkg" software package files follow the ABI (System V Application
Binary Interface) conventions for add-on
packages and are installed in /opt. It is wise to
change the default PATH setting to include /opt/bin in /etc/profile.

        PATH=$PATH:/opt/bin
        export PATH

If you do not have a /opt, you can create it with the subdirectories
/opt/bin, /opt/lib, /opt/man -- you could also use a symbolic link
to some other part of disk if you like (for example /usr/local) which
can be useful if you get short of free disk space.

To make the manual pages accessible to the /usr/ucb/man command
set the MANPATH environment variable to include /opt/man,
a typical MANPATH might be:

        MANPATH=/usr/share/man:/opt/man
        export MANPATH

The packages (pkg.tar files) should be installed as follows:

1. Extract the tar archive into /tmp.

$ cd /tmp

If compressed (.Z) then

$ zcat package.tar|tar xvf -
$ su
# pkgadd -d `pwd`

Many of the utilities include desktop icons for point and click
operation:

2. Installing graphically

On UnixWare 1.x:
----------------
To install graphically on UnixWare (after you have installed the package)
        Select the System_Setup icon from the Desktop.
        Select Application_Setup from System_Setup
        Wait while the system catalogs the applications
        Select the package icon from Application_Setup to get to
            Application_Setup:package_name
       Select the package icon and Finally click on the Install_to_desktop
        Selecting Applications from the Desktop you should
        then see the package icon.

On UnixWare 2.x:

For UnixWare 2.0 and later, use the App_Installer utility in Admin_Tools
after doing the pkgadd.

        Select the Admin_Tools icon from the Desktop.
        Select the App_Installer icon from Admin_Tools
        Select the icon of the package from the "All Applications
                currently installed" window
        Select Show_Contents
        Select the installable icon and hit Copy_to_folder
        Select Apply, followed by Ok.

Subject: T34) SMC NIC install & TF2047 (UW2.01)

Kevin R. Bulgrien (102174.1561@compuserve.com) reports:

There is a patch TF2047 that corrects a problem with the SMC NIC driver.  The
error that it fixes can lead to an install session failure:

If you are installing UW 2.01 on a system that is already attached to a network
which is in use, you will undoubtedly experience a system crash during the
portion of the setup which detects and installs support for the NIC.

To proceed with the installation without risk of this failure, disconnect the
system from the network until after the install is complete.

To proceed with the installation after it has locked up during the network
setup phase, reboot after you have disconnected the system from the
network.  Installation of the network card will proceed normally.

I experienced this failure a couple of times, and arrived at the above solutions
by trial, error, and reading over the TF listings - and noticed the SMC driver
patch.

This information is implied by the documentation of the TF2047 patch in that
it indicates that the SMC driver can crash the system if it receives packets
too quickly during the driver initialization, but I have not seen it
associated directly with problems experienced during an install.

Subject: T35)How can I read the size of installed memory in a UnixWare system?

        /etc/conf/bin/idtune NPROC 1200

Subject: T38) I've lost the root password, what do I do now?

If you can login as the "system owner", then you can use tfadmin(1m)
to change root's password.  This works on both UnixWare 1.x and 2.x:

    $ /sbin/tfadmin passwd root

or to delete the root password (remember to reset it afterwards)

    $ /sbin/tfadmin passwd -d root

Otherwise you need to use the emergency boot floppy (an EBF).


Subject: T39) How to recover with an Emergency boot?

Peter Lord writes:

At some time or other, you will find yourself with a UnixWare machine
which either you can't log into or won't boot up. Their are many
possible causes for this but perhaps the most common include forgetting
passwords, configuring the kernel incorrectly and editing system files
by hand incorrectly.

One example (now laughable - but not at the time!) was when I wanted to
bring the system into single user mode for admin. I edited /etc/inittab
to switch the default run-level to 1. Later, I put the run-level back to
6 (not 3!). This left me with a machine which continually re-booted
itself!

Creating an emergency boot disk set is an essential admin task. On
UnixWare 2, create a disk set by :-

     emergency_disk diskette1

This will take a few minutes. Note that this disk set is unique for you
machine. Also, as it contains all your HBA drivers, make sure you create
it after your machine is stable and fully installed.

When booting with your disk set, a mini version of UnixWare is booted
from the floppies. You will be presented with a short menu allowing you
to repair disks, mount disks and enter a shell. In my example above, I
could enter the shell and edit /etc/inittab before rebooting.

As well as creating an emergency boot set, you can also create a backup
of your whole machine onto tape and restore this tape with the emergency
boot set. See the  emergency_rec program to create such a tape.

Subject: T40) Where are the system messages and log files on UnixWare?

Peter Lord Writes:

As a UnixWare system administrator, you need to keep track of the
various messages that the system generates. But where are these
messages?

Console Messages

If you are using the graphical desktop, you may miss some messages
because they are written out to the console or your home virtual
terminal (VT).

You can switch from the graph VT to the home VT by pressing ALT-SYSRQ
together, then H. To get back to the graphical VT press ALT-SYSRQ F1.

Operating system messages

Occasionally, the kernel will want to print some message out to you.
This may be some information, warning or error messages. There are a few
ways to read these messages :-

1. /dev/osm devices. As root, you may access the /dev/osm* devices to
view these messages. The command "cat /dev/osm1" will print out the messages to
date and the command "tail -f /dev/osm1" will print out the last few
messages and will continue to print out new ones.

2. /var/adm/log/osmlog file. This file records the output of /dev/osm.
Old versions of this file (from previous boots) are kept in the same
directory. This file is usually readable by all.

3. Msg_Monitor. This is a graphical tool which monitors the operating
system messages from the desktop (found in the Applications folder). This is
configurable (so, for example, you can set it up to de-iconify on
receipt of a new message).

System messages

Application programs also want to alert you to possible problems.
Usually these will either be generated at the console or through the
/dev/osm interface.

However, it is possible to collect these messages by severity into a log
file. In fact, all the messages from all the machines on the network may
be collected together into one file. This system is syslog.

The syslog daemon (syslogd(1)) is started from /etc/inet/config. Make
sure you have a line thus in this file :-

/etc/inet/config:8:/usr/sbin/syslogd::y:/etc/syslog.conf::

And the configuration file /etc/syslog.conf should look something like this :-

*.err;kern.debug;daemon.notice;mail.crit;user.none      /var/adm/log/messages
*.alert;user.none                                       root
*.emerg;user.none                                       *
auth.info                                               /var/adm/log/authlog
*.debug                                                 @loghost

(Note in this example, loghost is an alias in /etc/hosts for the IS
monitoring machine)

Connection Server

The Connection server (cs(1)) is a daemon which establishes connections
for TLI/serial network services such as uucp, PPP etc. The log file for
the connection server is kept in /var/adm/log/cs.log.

However, if you are experiencing connection problems, the information in
this log file may not be detailed enough (for example, your uucp
connection is failing). The cs daemon can be run in debug mode to give
more information in the file  /var/adm/log/cs.debug by running cs with
the -d option.

Firstly, kill off the existing cs process (do a ps -edf | grep cs).
Secondly run cs -d (as root).

Subject: T41) How can I revert to the BSD form of (restricted) chown?

By default, chown() system call comes with the old AT&T behavior and
allows a user to change the ownership of a file he owns to that of any
other user on the system.

How can I modify the behavior to the BSD-form (only root can change
the ownership of a file)?

The BSD way is the FIPS 151-2 and XPG4 way, and indeed there is a tuneable
called RSTCHOWN. For strict conformance (and when testing for
POSIX FIPS 151-2, XPG etc) this should be set to one.

/etc/conf/bin/idtune -g RSTCHOWN  will return its value.

To set it do

     # /etc/conf/bin/idtune RSTCHOWN 1
     # /etc/conf/bin/idbuild

and then reboot.

Subject: T42) Why do I get 'syslog: accept: SIOCGPGRP failed errno 22' in syslog files ?

If you have setup syslog log you may sometime see messages like :

Aug  1 13:05:26 myhost syslog: accept: SIOCGPGRP failed errno 22

It's logged at level USER, thus you may not see it if you don't log
this level.

These messages are related to some program for which system libraries
were not specified in the correct order. A common sample is Sendmail
8.7.5.

If the program is compiled with C library before socket & nsl libs you
may get them.

To simply correct the problem, you have to find which program was
badly compiled and correct the Makefile. Just put -lc after -lnsl
-lsocket, and all should be fine.

Try 'psradm':

      EXAMPLES
            To unlock a processor, or bring it online:

                        psradm -n processor_id

            To lock a processor, or take it off-line:

                        psradm -f processor_id

Subject: T44) How to avoid the check for open virtual screens when loggin on the console?

Q Sometimes it happens that I can't login at the console
window ( h) while logged into the desktop.
I get a message that vt01 is still open and have the choice
to close it by hand. I then need to log off the desktop to
be able to get a login prompt on the console.

Does anybody know how to avoid the check for open virtual
screens?

A. Curt Smith writes:

tymon is a pain for too many reasons.  Here's my work around for
hacking both: /etc/inittab (this file is manufactured from /etc/conf/init.d/*)
and /etc/conf/init.d/consoles.  The later is a new file in that dir.

/etc/conf/init.d/consoles:

v1:23:off:/etc/getty vt01 console
v2:23:off:/etc/getty vt02 console
v3:23:respawn:/etc/getty vt03 console
v4:23:respawn:/etc/getty vt04 console
v5:23:respawn:/etc/getty vt05 console
v6:23:respawn:/etc/getty vt06 console
v7:23:respawn:/etc/getty vt07 console
v8:23:respawn:/etc/getty vt08 console

The above gives you virtual consoles on: Alt-SysReq-F[3-8]
Cat the above file to the end of /etc/inittab

Modify /etc/inittab and /etc/conf/init.d/kernel

Modify line to:
co:12345:off:/usr/lib/saf/ttymon -g -v -p "Console Login: " -d /dev/console -l console

Add line:
co1:12345:respawn:/etc/getty console console

BTW: for UnixWare 2.x and 2.1 I've found ttymon to be friendlier than UW 1.x and
not requiring being disabled as the above modification does.

You be the judge as to how far you want to free yourself from the
ttymon/sac/saf tyranny.

Personally, I don't have a problem with ttymon, but... the very first
thing I do after a new install is remove the '-v' option from the
console ttymon.  I don't see why it's the default configuration.
Without the '-v', you can login and logout of the home "console" without
shutting down the X server running on vt01.

The inittab file (and /etc/conf/init.d/kernel) should look something
like this:

co:12345:respawn:/usr/lib/saf/ttymon -g -p "Console Login: " -d /dev/console -l console

Here's the description of the '-v' option from the ttymon man page:

          Options
             In Express Mode (or standalone) ttymon takes the following
             options:

            -v     On startup, ttymon will list all open virtual terminals
                   (vts) associated with the device specified (typically
                   /dev/console).  On exit, the user will be prompted to
                   close all open vts either manually or automatically.
                   Choosing manual places the user in the highest numbered
                   vt at which point the user must manually exit from each
                   vt.  Choosing automatic will cause the signals SIGHUP
                   and SIGTERM to each open vt, then after 3 seconds
                   SIGTERM will be sent to each open vt to ensure
                   termination.

                   For systems running with the Enhanced Security Utilities
                   installed, the -v option will disable trusted path
                   processing.  [See ttyadm(1M)].

Subject: T45) How to increase per-process size limits to avoid Virtual MEmory Exceeded errors?

Problem:
We have an application developed locally that needs as much memory
as possible to load 10-15MB digital map files. The default setup on
UnixWare 2.03 systems is 32 MB with 64 MB swap, but the program gets
a "Virtual Memory Exceeded" error around 14MB. Other tests show this
error occurs at 16MB predictably.

Solution. MS writes:

You need to up your process-size limits.  Either with the ulimit
or limit commands (for Bourne/Korn and C shell, respectively) on
a per-process base (only works for root), or by retuning the
kernel parameters

        # /etc/conf/bin/idtune SDATLIM 33554432         ## soft
        # /etc/conf/bin/idtune HDATLIM 33554432         ## hard
        # /etc/conf/bin/idtune SVMMSIZE unlimited       ## soft
        # /etc/conf/bin/idtune HVMMSIZE unlimited       ## hard
        # /etc/conf/bin/idbuild -B
        ...
        reboot!

The first two set the maximum size of the data segment (the "heap")
to 32 MB, the second two remove the limit on the total process size
(which is, however, implicitly limited by 32MB of heap + 16MB of
stack + program text).  Don't raise the stack limit, or a runaway
recursion will kill you.
