Introduction
This document presents very important information that you need to install SCO UNIX.
The first section of this document is a list of helpful tips on NOS installation, the second
section is a step-by-step installation guide.
NOTE: Hewlett-Packard has more than one Disk Array Controller (DAC) for the
NetServer product family. In this document the term "HP Disk Array" refers to
the EISA and PCI Disk Array Controller models C3609A and C3610A,
respectively. The term "HP NetRAID" refers to the HP NetRAID and NetRAID-
1 PCI Adapters models D4943A and D4992A, respectively. The term “HP
NetRAID 1Si refers to model number D2140A. The term “HP NetRAID 3Si”
refers to model number D5955A. The term “HP Embedded RAID” refers to the
built in RAID controller on the HP NetServer LH 3 and LH 4.
The HP NetServer E 30 does not support either DAC.
The HP NetServer E 40 , E 45 and E 50 support the HP NetRAID DACs only.
The HP NetServer E 60 only the HP NetRAID 1Si and HP NetRAID 3Si.
SCO MPX 3.0 does not work correctly on multiprocessor systems using the Intel
Pentium Pro, Pentium II or Pentium III processor (e.g. the NetServer LC II, LC 3,
LD Pro, LH Pro, LH II, LH 3, LH 4, LPr, LX Pro, LXe Pro, LXr Pro and LXr
8000).
SCO Open DeskTop 3.0, OpenServer 3.0, and MPX 3.0 are not supported on the
NetServer LC 3, LH 3, LH 4, LXr 8000, and LXr8500.
SCO OpenServer 5.0.x is supported on the NetServer E60, E 800 LPr, LC2000,
LC3, LH3, LH3000, LH4, LXr 8000 and LXr8500

Section 3. On-Line Information and Software Sources
Section 1. General Tips
Introduction
The following subsections discuss problems that you may encounter when installing SCO
UNIX 3.2v4.2, Open Desktop (ODT) 3.0, OpenServer 3.0, MPX 3.0, and OpenServer
5.0.x.
SCO UNIX installation procedures include installing SCO UNIX files, loading all
required drivers (including BTLD (Boot Time Loadable Driver) packages), and linking
information to the kernel.
As a rule, select fully configurable, rather than automatic, initialization.
CaSe SeNsItIvE
All version of UNIX are very case sensitive and you need to be absolutely sure that you
type in the commands exactly as instructed. Almost all UNIX commands are in lower
case so if you are unsure try lower case first.
Start Counting At Zero
In almost all cases a UNIX system will start counting at ZERO. Therefore, SCSI
Controller 0 is the first controller, SCSI Channel 0 is the first channel, Hard Disk 0 is the
first hard disk, etc.
Set Up All Cards In ECU or BIOS Setup Utility
SCO UNIX likes to have all cards and disk drives configured in CMOS to work properly.
SCO can actually read the system configuration information. This means that before you
try to configure SCO to use a particular adapter card in the system go in and make sure
that it is set up in the ECU or BIOS setup utility. Even if it is an ISA adapter without a
config file go into the ECU and add a "Generic ISA Adapter" and assign the appropriate
resources such as DMA, Memory, and IRQ to match the settings of the card. (There is a
config file for a Generic ISA Adapter on the NS#2 diskette or Navigator CD-ROM. Add
it as a non-HP board).
Installation To Disk Arrays
Installation to a logical drive, on a disk array, larger than 2048 MB is not recommended.
For SCO versions 5.0.x, larger drives are possible but for backwards compatibility and
ease of system administration logical drives smaller than 2 GB are recommended for your
root drive. Utility Partition Access Disabled

During SCO UNIX installation, access to the Utility Partition built by the Configuration
Assistant is disabled. Select "Skip" if Configuration Assistant asks you to build the
Utility Partition.
Installation Media
The following installation media is required in addition to the main product CD-ROM or
tape to install SCO UNIX.
For UNIX 3.2.4.2: N1, N2, and M1 diskettes, and the HP Drivers Diskette.
For ODT 3.0 and OpenServer 3.0: N1, N2, and the Release Supplement diskettes, and the
HP Drivers Diskette.
For MPX 3.0: MPX 3.0.0j, APIC 1.1 from the AHS 3.4.0 distribution, and SLS
UOD393E (or later) "Performance Supplement" diskettes. You may also want to use
SLS UOD421A (or later) to get the latest APIC driver which supports MPS Specification
1.4.
For OpenServer 5.0: The Boot Disk, the Release Supplement 5.0.0d (or later) diskettes,
and the AHS 5.2.0 (or later) BTLD for the latest arad and alad SCSI drivers, and the HP
Drivers Diskette.
For OpenServer 5.0.2: The Boot Disk, and the AHS 5.2.0 (or later) BTLD for the latest
arad and alad SCSI drivers, and the HP Drivers Diskette.
For OpenServer 5.0.4: The Boot Disk, the Release Supplement 5.0.4c, and the HP
Drivers Diskette.
For OpenServer 5.0.5: The Bootable CD-ROM, the Release Supplement 5.0.5a, and the
HP Drivers Diskette.
For OperServer 5.0.6: The Bootable CD-ROM and the HP drivers Diskette.
Swap Space
You may wish to increase the swap space from the default provided. UNIX uses the
swap space to swap the least-recently used pages in and out of memory. If you have the
disk space available, you might consider using the default, or doubling the size of the
physical memory, whichever is greater.
Additional File Systems
Selecting "/u file system", or some other file system in Release 5.0.x, sets up a separate
file system in addition to the root file system. If you select an additional file system, you
will then be asked to allocate disk space between your root and your additional file
system.

Be sure to leave enough space in your root file system for installing future applications.
Remember that any application files that you place in your /u file system reduce the space
left for user data files.
A scratch division is an area that FSCK (file system check) uses to record data in case of
a problem. It is probably safer to accept a scratch division, so that FSCK can function
properly if you ever need it.
Configuring a Mouse
All HP NetServers have a PS/2 style mouse. This is also know as a mini-DIN or
keyboard mouse. If you want to configure such a mouse as part of the operating system
installation, choosing "Low resolution Keyboard mouse" is the safest choice for
specifying mouse type. If this is not correct, it can always be changed after the system is
up and running.
Configuring Video for UNIX
When configuring the video for UNIX, standard VGA is the safest choice. You can enter
the correct video driver after the system is up and running. The following video chips are
used in the HP NetServers:
E 30: S3 Trio 64V+, 1MB or 2MB video memory
E 40, LC II, LC 3, LH 3, LH 4, LPr, LXr 8000: Cirrus Logic CL-GD5446, 1MB or 2MB
video memory
E 45, E 50: Cirrus Logic CL-GD5446, 2MB video memory
E 60: ATI Rage IIc AGP video card, 4MB video memory
LC Plus, LD Pro, LH, LH Plus, LH Pro and LH II: Trident TVGA9000I, 512KB video
memory
LS, LX Pro, LXe Pro, LXr Pro: Cirrus Logic CL-GD5424, 512KB or 1MB video
memory
LC 2000, LH 3000 LH 6000, LT 6000r: ATI Rage II c on board card, 2MB video
memory
E 800: ATI Rage XL on board card, 4MB video. Driver and install guide can be copied
from Navigator CD SCO Driver diskette
The wrong video driver can produce blank or unreadable screen displays at the higher
(greater than 640 x 480 VGA) resolutions.

BTLD Tips
The HP NetServers use the BTLD for the internal SCSI controllers. The BTLD is a
driver that can be link-edited into the UNIX system kernel during the booting process.
The link-editing is done by boot (HW) after the driver is loaded into memory, but before
the kernel is started. The HP NetServer Manager CD creates a diskette containing the
SCO UNIX BTLDs.
For the UNIX 3.2v4.2 and 3.0 products, you need an HP disk controller driver diskette
that is created by the HP NetServer Navigator CD. This diskette contains the alad, arad,
amird, and mdac drivers.
For OpenServer 5.0.x, the SCSI controller drivers are built into the SCO product. HP
recommends that you use the latest arad and alad drivers that SCO ships. These drivers
are available from SCO on their AHS 5.2.0 (or later) BTLD disk. HP only ships the
drivers for the HP Disk Array Controller (mdac), the HP NetRAID Controller (amird),
the Adaptec alad driver (use alad325 on the link line), the Adaptec blad driver for SCSI
Ultra 2 (use blad325 on the link line) and the Symbios slha driver (use symha on the link
line), but not the Adaptec arad driver, on the driver diskettes that are created by the HP
NetServer Navigator CD.
Driver Names for HP-Supplied Controllers
The following table lists the names of required drivers for the HP-supplied controllers.

NOTE: HP currently does not support ultra SCSI mode on the AIC7880
controllers when they are connected to the HP Storage System 6. Ultra SCSI
mode is supported for disks installed in the HP NetServer cabinet and in the HP
NetServer Rack Storage System 8 and 12.
Troubleshooting
SCO OpenServer is very specific about the hardware configuration it expects when
installing. The following limitations apply:
The root hard disk and the install device should both be on the primary SCSI channel.
The root hard disk must be SCSI ID 0. The first SCSI tape drive must be SCSI ID 2.
The first SCSI CD-ROM drive must be SCSI ID 5, or for an IDE CD-ROM use the
CD-ROM as the master device.
The correct SCSI ID is especially important if you are installing from the tape or CD-
ROM drive. If you have a complicated hardware configuration, install SCO
OpenServer using only the minimum system required to install. All additional
hardware can be added afterwards.
N1 and N2 Diskettes
SCO OpenServer comes on floppies, QIC525 tape, or CD-ROM. All versions prior to
OpenServer 5.0.5 require booting the system off the N1 Installation diskette, and perhaps
using the N2 diskette, to build a rudimentary UNIX system as part of the installation
process. OpenServer 5.0.5 has a bootable CD-ROM for installation.

Any error that occurs when you first boot off the N1 diskette is a hardware problem.
Either some piece of hardware is bad or there is a serious hardware configuration error.
Fix this problem before trying to install SCO OpenServer.
When booting off the N1 diskette, always use the link command to link the appropriate
SCSI driver into the system (alad for the E 30, E 40, E 45, E 50, E 60, LC II, LC 3, LD,
LH, LS, or LX; symha for the LH 3, LH 4, LPr, LXr 8000, or LXr 8500). Refer to the
SCO Installation Manual for how to use the link command and the SCO OpenServer
drivers disk for the various NetServers. This driver is not permanently linked into the
kernel until the end of the SCO OpenServer installation.
Most installation errors will occur after inserting the N2 diskette.
Common Errors
The following is a list of error messages and solutions.
WARNING: HD: NO ROOT DISK CONTROLLER
This usually indicates that the NetServer SCSI driver (e.g. alad) was not linked into the
system. One way this can happen is when the installation reaches the point where you
have the following choices:
1. Continue with Installation
2. Install additional packages and you chose 1.
This is the wrong choice when you are adding a BTLD driver such as alad to the
system. You must choose 2 to complete the installation of the alad driver. This may
also happen if the root hard drive is not on the primary SCSI channel.
ALAD: ADAPTER 0 ERROR: SELECTION TIMEOUT
This error could occur if the root hard disk SCSI ID is some value other than 0. The boot
HD must be SCSI ID 0. This could also occur if the hard disk is on the wrong channel in
systems that have the dual channel SCSI.
ALAD: ADAPTER 0 ERROR: SELECTION TIMEOUT: COULDNOT EXTRACT
FILES FROM /DEV/...
The ... in the error message indicates that device that you are using to install SCO
OpenServer. For example, it will be: /dev/Stp0 if you are installing from the QIC525
tape. This message says that SCO OpenServer could not access the device. Check that
the device is working. Check that the SCSI ID is correct. Using any SCSI ID other than
the ones previously listed will not work.

The System Hangs without any Error Messages
This is probably a SCSI bus problem. Check the SCSI setup for errors. Make sure all the
SCSI devices are seen on boot up. One symptom of a SCSI bus termination error is that
some devices are not seen on boot up. Check for bad SCSI devices, bad SCSI
connectors, bad termination, duplicate SCSI IDs.
Serialization Fails
Once you have verified that you have entered the correct serial number/activation key,
check the permissions on the /tmp directory (l -d/tmp). The /tmp directory should have
the following permissions: drwxrwxrwt.
If the permissions differ, enter the following command: chmod 1777 /tmp.
Section 2. Installation Guide
Large Memory Access
SCO UNIX 3.2v4.2, Open DeskTop 3.0, OpenServer 3.0, and MPX 3.0 are limited to 512
MB of physical memory (RAM). The system will ignore any memory above 512 MB.
SCO OpenServer 5.0.0 and 5.0.2 can access 512 MB of physical memory (RAM) without
any patches. The systems can access up to 4 GB of memory by installing the SCO Large
Server Supplement. OpenServer 5.0.0 requires Large Server Supplement version 1.0.0.
OpenServer 5.0.2 requires Large Server Supplement version 1.1.0. OpenServer 5.0.4,
and later, supports 4 GB of memory without requiring patches.
When installing OpenServer 5.0.0 or 5.0.2 on systems with more than 2048 MB (2 GB)
of memory you will need to limit the memory search during the installation process. To
limit the search add the following string to the boot line you use to start the system
installation:
mem=1m-1024m
After the system is installed you can set the correct memory size in the file
“/etc/default/boot”. See the man page for “boot” for the syntax of this file.
There is a defect in OpenServer 5.0.0 and 5.0.2 that causes the system to report a negative
memory size on systems with more than 2 GB of memory. This defect does not appear to
cause operational problems but it may cause problems for shell scripts that use the
“memsize” command.
SCSI Extended Translation Setting
The SCSI extended translation setting for disks with a capacity larger than 1 GB should
be set to ‘disabled’ for all versions of SCO UNIX, Open DeskTop, and OpenServer 3.0.
For OpenServer 5.0.x you can use SCSI extended translation. (Run the EISA

Configuration Utility, or the AIC SCSI BIOS utility <Ctrl>-A, or <Ctrl>-C for Symbios
BIOS utility to set this parameter.)
MPS Table Setting On NetServer LS and LX for SCO MPX
For the HP NetServer LS and LX with multiprocessors, you must set the MPS
configuration parameter to the correct MPS Table setting.
1. Run the EISA Configuration Utility.
2. Move to the MPS Table selection.
3. Select the MPS table value 1.1 for SCO MPX 3.0. You may use MPS table value 1.4
if you install SCO patch /SLS/uod421a (available on SCO's FTP site).
Select MPS table value 1.4 for SCO OpenServer 5.0.x.
Logical Disk Size for the HP Disk Array Controller and the HP
NetRAID Adapter
During system configuration, the DAC configuration utility on the HP NetServer
Navigator CD-ROM helps you set logical disk size in the disk array configuration
process. If the boot drive is on the disk array controller, set the logical disk size to 2048
MB or less.
HP Disk Array Controller Logical Disk Addressing
The logical disks configured on the HP Disk Array controller are all addressed as LUN
(logical unit number) 1. The individual logical disks are addressed through the SCSI ID
field in the SCO "mkdev" command. For example, the first logical disk is SCSI ID 0,
LUN 1 and the second logical disk is SCSI ID 1, LUN 1.
HP NetRAID Controller Logical Disk Addressing
The logical disks configured on the HP NetRAID controller are all addressed as SCSI ID
0. The individual logical disks are addressed through the LUN (logical unit number)
field in the SCO "mkdev" command. For example, the first logical disk is SCSI ID 0,
LUN 0 and the second logical disk is SCSI ID 0, LUN 1.
HP NetRAID Controller Utilities
Two utility programs are installed on the system when the HP NetRAID driver is
installed. The first utility is the HP NetRAID controller monitor program "amirdmon".
Amirdmon is started when the system enters multi-user mode. The second utility is the
controller configuration program "megamgr". Megamgr can be run when the system
administrator needs to reconfigure the HP NetRAID controller.

Booting from the Embedded SCSI Controller
The system boots from the drive with the lowest SCSI address (0--zero) on the embedded
SCSI host bus adapter. On the NetServer LD, LH and LS disk arrays, the upper middle
drive slot has SCSI ID 0. On the NetServer LX, check the SCSI configuration label to
see how your disk slots are numbered. If you place the boot drive in another slot, your
system may not boot. On the HP NetServer E 30, E 40, E 45, E 50, and E 60 you need to
use jumpers on the disk drives to set their SCSI addresses.
Drivers for HP Network Cards Available on HP NetServer CD-ROM
Some NetServer models come with a bundled network interface card (NIC). The SCO
3.0 and 5.0 drivers for the HP network cards are available by using the "Diskette Library"
feature in the "NetServer Utilities" section of the HP NetServer Navigator CD-ROM.
Make sure you select the NIC driver that matches your NIC model number and NOS
version. Once the NIC driver diskette is created, you can load the NIC driver onto your
system using the "custom" command. After the driver is loaded you must run "netconfig"
to configure the card into the UNIX kernel.
Manually Configure the Network Speed on the HP J3171A and D5013A
NIC
When configuring the HP J3171A or D5013A NIC using SCO’s "netconfig" utility you
must manually set the adapter for the network speed. The auto detection feature of the
driver does not currently work. Follow these steps to set the speed:
1. Run netconfig
2. Select the networking product that you need to configure
"HP DESKDIRECT 10/100 TX LAN ADAPTER"
3. Select "Hardware"
4. Select "Modify hardware configuration"
5. Select "Advanced options"
6. Select the "Media Speed"
Do not select "AUTO", you must choose either 10 or 100.
7. Choose "Continue", followed by another "Continue"
8. Exit netconfig
9. Answer "y" to the kernel rebuild, boot and rebuilt prompts

10. Reboot your system
Installing Multiple NICs
When you are installing more than one NIC in your system you need to install and
configure one NIC at a time. Put the first NIC in the system, run "netconfig" to configure
the card, turn off your system, put the second NIC in the system, and then run "netconfig"
to configure the second NIC.
The D5013A NIC driver does not support more than 2 D5013A NIC cards in the system.
Adding a DAC as a Secondary Controller to an IDE System
When adding a DAC (PCI or EISA) as a secondary controller to a SCO OpenServer 5.0.x
system that has been installed to an IDE boot disk, you must edit some SCSI
configuration files before loading the DAC driver (using "installpkg"). Follow these
steps:
1. Change directory to "/etc/conf/sdevice.d".
2. Edit the files "Sdsk", "Srom", and "Stp". In each case, change the second field on all
three files from "N" to "Y".
3. Change directory to "/etc/conf/cf.d".
4. Relink the kernel using "./link_unix".
5. Reboot the system.
6. For the HP Disk Array Controller: Load the mdac driver using "installpkg". When
asked if you want to replace the mdac driver that is already installed answer "Y".
For the HP NetRAID Controller: Load the amird driver using "installpkg".
Installing SCO UNIX 3.2v4.2, SCO ODT 3.0, OpenServer 3.0, and MPX
3.0
IDE/ATAPI CDROMs (on E 30, E 40, E 45, and LC II) and Large IDE Disk Drives
On systems containing either an IDE/ATAPI CDROM drive or an IDE disk drives with
more than 1024 cylinders, 16 heads, or 63 sectors per track, when you install SCO UNIX
3.2v4.2 or Open DeskTop / OpenServer 3.0 you need to use a new EIDE/ATAPI driver
from SCO.
SCO has created a new EIDE/ATAPI driver which supports IDE/ATAPI CDROM drives
and EIDE disks. The new driver can be obtained by anonymous FTP from ftp.sco.com.
The files are /SLS/uod453a.Z and /SLS/uod453a.ltr.Z. Uncompress the file uod453a.ltr.Z
and then read the file uod453a.ltr for instructions on how to use the new driver.

IDE Translation Mode
1. Run the EISA Configuration Utility on the HP NetServer Navigator CD-ROM.
2. Go to the IDE configuration section.
3. Highlight the IDE Translation Mode and change it to Standard CHS, unless you are
using the new N1 diskette described above.
Installation Instructions
The following instructions help you to install SCO UNIX 3.2.4.2, Open Desktop (ODT)
3.0, OpenServer 3.0, Enterprise System 3.0, and MPX 3.0 on your HP NetServer system.
NOTE: SCO Unix 3.2v4.2 does not support Plug And Play mode for interface
cards. Plug And Play must be disabled on the card and the card must be manually
configured.
Two HP D5013A or J3171A NIC cards can not share the same IRQ.
On the HP NetServer LC II you can not combine the 3COM 3C905 NIC with
either the HP D5013A or J3171A NIC.
1. Use the HP CD-ROM installation utility to configure your system hardware. This
utility creates an SCO driver diskette (the "Drivers Diskette"). You will use this
diskette when you install the SCO operating system.
2. Insert the SCO N1 diskette and turn on your NetServer. For the HP NetServer E 30,
E 40, E 45, or LC II you will need to follow the instructions that come with SCO’s
SLS uod453a (see IDE/ATAPI CDROM section above).
3. You must tell SCO UNIX to use Boot Time Loadable Drivers (BTLD) for the
hardware that you have. You do this with the “link” command at the “Boot:” prompt.
If your CD-ROM is connected to the internal IDE controller you will need to use the
new EIDE/ATAPI driver from SCO's SLS uod453a (see IDE/ATAPI CDROM
section above).
If your CD-ROM is connected to the internal embedded SCSI controller, use the
following rules to determine what to enter at the “Boot:” prompt.
If installing to a disk on the integrated SCSI controller you simply type in link at
the “Boot:” prompt and hit return. You then type in the name of the driver that you
wish to link.
If installing to a logical drive on either the HP Disk Array or HP NetRAID
controller use the following link command at the “Boot:” prompt:

defbootstr link="scsi-driver array-driver" Sdsk=array-
driver(0,0,0) Srom=scsi-driver(0,5,0)
for example installing on a NetServer LH, LS, or LX to an HP NetRAID the
command is:
defbootstr link="alad amird" Sdsk=amird(0,0,0)
Srom=alad(0,5,0)
if installing on a NetServer LH, LS, or LX to an HP Disk Array (Mylex) the
command is:
defbootstr link="alad mdac" Sdsk=mdac(0,0,0)
Srom=alad(0,5,0)
The link portion of the above command tells the operating system what BTLD drivers
to use, the Sdsk portion tells the installation which of the controllers on the system
has the boot disk connected to it, and the Srom portion tells the installation which of
the controllers on the system has the CD-ROM connected to it.
NOTE: When using the HP NetRAID Controller, you can safely ignore the
message "WARNING: SCSI boot option(s) ignored: Unknown host adapter
driver".
If you are installing several BTLD packages, the order of these drivers is important
for proper loading from the CD-ROM.
4. When prompted to insert the driver diskette that contains the drivers you specified,
insert the Drivers Diskette.
5. Follow the instructions in the "SCO Installation and Upgrade Guide" to complete
your system installation.
NOTE: For SCO UNIX 3.2v4.2: When the Run Time Installation is complete,
make sure you select the "Install Additional Software" option. This ensures that
the Link Kit is installed and available for later driver integration.
When using SCSI disks larger than 4 GB you must select either "Fully
Configurable Installation" (for UNIX 3.2v4.2) or "Preserve" installation type (for
Open DeskTop and OpenServer). You must then fdisk the physical disk into
partitions that are each 4 GB or smaller.

Installing SCO OpenServer 5.0.x
Large IDE Disk Drives and IDE/ATAPI CD-ROMs (on E30, E 40, E 45, E 50, E 60,
LC II, LC 3, LH 3, LH 4 and LPr)
For OpenServer 5.0.0 and 5.0.2 there is a problem using IDE disk drives larger than 2
GB. There is also a problem accessing some IDE (ATAPI) CD-ROM drives. SCO has
released a new “wd” driver BTLD diskette that fixes these problems. You will need to
get the SCO SLS OSS451B (or later) from SCO’s ftp site. Please read the instructions
for this SLS before using it. These problems have been fixed in OpenServer 5.0.4.
Installation Instructions
The following instructions help you to install SCO OpenServer 5.0.x on your HP
NetServer computer.
NOTE: SCO OpenServer 5.0.x does not support Plug And Play mode for interface
cards. Plug And Play must be disabled on the card and the card must be manually
configured.
The mdac driver can not share IRQs, neither with another HP DAC card nor with
other cards.
Two HP D5013A or J3171A NIC cards (and the E 60 embedded NIC) can not
share the same IRQ.
On the HP NetServer LC II you need to make sure you have the latest NIC drivers
from either SCO or the NIC manufacturer. The NIC driver needs to have a fix for
the “I-Distributed” problem. If your driver does not work you can contact SCO
Support.
For OpenServer 5.0.x, the SCSI controller drivers are built into the SCO product. HP
recommends that you use the latest arad and alad drivers that SCO ships. These drivers
are available from SCO on their AHS 5.2.0 (or later) BTLD disk. HP only ships the
drivers for the HP Disk Array Controller (mdac), the HP NetRAID Controller (amird),
the Adaptec alad driver (use alad325 on the link line), the Adaptec blad driver for SCSI
Ultra 2 (use blad325 on the link line), and the Symbios slha driver (use symha on the link
line), but not the Adaptec arad driver, on the drivers diskettes that are created by the HP
NetServer Navigator CD.
1. Use the HP CD-ROM installation utility to configure your system hardware. This
utility creates an SCO driver diskettes (the "Drivers Diskettes").
2. Insert the SCO Boot diskette (or 5.0.5 bootable CD-ROM) and turn on your
NetServer.
3. What you type at the "Boot:" prompt depends upon your configuration. You must
now specify which drivers to install to.

NOTE: For OpenServer 5.0.0 you must type “ahslink” instead of “link”.
OpenServer 5.0.2 (and later) use “link”.
A. If your CD-ROM or tape, and boot disk are connected to the internal
embedded SCSI controller on NetServer models that use either the alad or
arad driver (see table earlier in this document), press Enter or type “restart”.
OpenServer release 5.0.x automatically detects the controller.
Restart
B. If your boot disk is connected to the internal embedded SCSI controller on a
NetServer LH 3, LH 4, or LPr then you need to replace the slha driver that ships
with OpenServer 5.0.x. At the “Boot:”” prompt type:
restart link=slha Sdsk=slha(0,0,0,0) Srom=wd(0,0,0,0)
Note that you use slha in the link part, and “slha” in the Sdsk part. While
loading the driver from the driver diskette you will be prompted to replace the
existing driver by entering the table entry numbers that are listed (typically 28
and 2).
If you are not using the Symbios SCSI controller on these systems you should
enter “disable=slha” at the “Boot:” prompt.
C. To install OpenServer 5.0.0 or 5.0.2 to the HP NetServer LXr Pro you will
need to use a new N1 diskette for SCO SLS OSS444 (or later). The NetServer
LXr Pro has the CD-ROM connected to SCSI A and the boot disk connected
to SCSI B. The OSS444 N1 diskette contains multiple instances of the “alad”
driver built in. At the “Boot:” prompt type:
restart Sdsk=alad(1,0,0,0) Srom=alad(0,0,5,0)
If you then install SCO Advanced Hardware Supplement (AHS) 5.2.0 after
the system is installed you will have to manually edit the file
“/etc/conf/cf,d/mscsi” to change the “number” field for the “Sdsk” line from
“1” to “0”, and the “Srom” line from “0” to “1” since the “alad” drivers in
OSS444 and AHS 5.2.0 use a different scheme to number controllers. After
editing the “mscsi” file you must relink the kernel:
cd /etc/conf/cf.d
./link_unix -y
Then reboot your system.
If you rebooted your system after installing AHS 5.2.0 but before editing the
“mscsi” file your system will not boot. You must reboot your system using an
old kernel by typi ng “unix.old” at the “Boot:” prompt. You will then be able

to edit the “mscsi” file, relink the kernel, and reboot.
OpenServer 5.0.4 requires a new N0 boot diskette from patch OSS463A. At
the “Boot” prompt type:
restart Sdsk=alad(1,0,0,0) Srom=alad(0,0,5,0)
D. For the HP NetServer E 30, E 40, E 45, E 50, E 60, LC II, LC 3 or LH 3
(where an IDE/ATAPI CD-ROM is used) type:
For OpenServer 5.0.0 and 5.0.2 use SCO SLS OSS451B (or later) to get the
wd driver:
restart link=wd Sdsk=alad(0,0,0,0) Srom=wd(1,0,0,0)
For OpenServer 5.0.4 the built in wd driver will find the IDE/ATAPI CD-
ROM. There is a problem in 5.0.4 where the CD-ROM will always be listed
as the slave device on the primary IDE controller. For the HP NetServer E 30,
E 40, E 45 and E 50 the CD-ROM is the master device on the secondary IDE
controller. For the HP NetServer LC II, LC 3 the CD-ROM is the master
device on the primary IDE controller.
E. If you have your system (root) disk is on the HP Disk Array Controller, you
must load the mdac driver; type:
restart link=mdac Sdsk=mdac(0,0,0,1)
Srom=alad(0,0,5,0)
for the NetServer E 30, E 40, E 45, E 50, LC II, LC 3 or LH 3 running
OpenServer 5.0.0 or 5.0.2 type:
restart link=“mdac wd” Sdsk=mdac(0,0,0,1)
Srom=wd(1,0,0,0)
for the NetServer E 30, E 40, E 45, E 50, LC II, LC 3 or LH 3 running
OpenServer 5.0.4 type:
restart link=mdac Sdsk=mdac(0,0,0,1)
Srom=wd(1,0,0,0)
When loading the mdac driver, you must replace the old mdac driver by
entering r.
F. If you have your system (root) disk is on the HP NetRAID controller, you
must load the amird driver; type:
restart link=amird Sdsk=amird(0,0,0,0)

Srom=alad(0,0,5,0)
for the NetServer E 30, E 40, E 45, E 50, LC II, LC 3 or LH 3 running
OpenServer 5.0.0 or 5.0.2 type:
restart link=“amird wd” Sdsk=amird(0,0,0,0)
Srom=wd(1,0,0,0)
for the NetServer E 30, E 40, E 45, E 50, LC II, LC 3 or LH 3 running
OpenServer 5.0.4 type:
restart link=amird Sdsk=amird(0,0,0,0)
Srom=wd(1,0,0,0)
for the NetServer E 60 running OpenServer 5.0.5 type:
restart disable=alad link=amird Sdsk=amird(0,0,0,0)
Srom=wd(0,0,0,0)
4. There is a bug in the OpenServer 5.0.4 Installation Query Manager which may make
phantom disks appear at the point where you are configuring the file systems on the
disks. Until SCO fixes this problem you are advised to “defer” configuring all disks
except the root disk until after the system is fully installed. Your additional disks and
filesystems can be configured using “mkdev” after the system is installed.
5. There is another bug in OpenServer 5.0.4 where multi-processor systems using the
“alad” driver and SCO ArcServer Lite will hang during system boot. SCO is working
on a new “alad” driver to fix this problem.
6. Follow the instructions in the SCO Installation and Upgrade Guide to complete your
system installation.
Apply SCO SLS OSS452A Kernel Mode Trap Type 0x0000000F Patch
For OpenServer 5.0.0 and 5.0.2, SCO has found a problem with some Pentium Pro
machines that are capable of running multiple CPUs but only have a single CPU
installed. In some cases the system will panic with the panic message:
PANIC: k_trap kernel mode trap type 0x0000000F
SCO has releases a patch that will prevent the system from panicing. Install SCO SLS
OSS452A (or later) which is available from SCO’s ftp site. Follow the instructions in the
file oss452a.ltr on how to apply the patch.
This fix has been incorporated into OpenServer 5.0.4.

Apply SCO SLS OSS449F Network Performance Patch
For OpenServer 5.0.0, 5.0.2, and 5.0.4, you will need to install SCO’s Support Level
Supplement (SLS) OSS449F to correct many known problems with TCP/IP, NFS, and
Unix components of SCO OpenServer Release 5.0.0, 5.0.2, and 5.0.4, and SCO Internet
FastStart Release 1.0.0 and 1.1.0.
To get the SLS, ftp to SCO and get their SLS files "oss449f.Z" and "oss449f.ltr". Follow
the instructions in the file oss449f.ltr on how to apply the patch.
Problem in SCO Release Supplement 5.0.4c
The SCO 5.0.4c release supplement has a bug that will cause the text based screens to not
display a login prompt if you have a DAC in your system. To get around this problem
you can login on the graphical screen (<F2>), type “ps -ef | more”, find the process that is
“defunct” and kill that processes parent by typing “kill -9 <ppid>“ where <ppid> is the
parents process id. You have have to do this each time you reboot the system. Contact
SCO Support for the latest information on this bug.
Release Supplement 5.0.5a Fixes SMP and IRQ Sharing Issues
If you are running SCO OpenServer 5.0.5 you should install SCO Release Supplement
5.0.5a (or later) to your system. RS 505a fixes a number of networking, multi-processor,
and IRQ sharing issues. RS 505a must be installed after SCO SMP support is installed.
Please see the release notes for RS 505a on the SCO web site for more details.
Floppy Read or Write Errors
If you experience read or write errors on the floppy drive you may want to tune the
floppy controller driver. To do this follow these steps.
Edit the file /etc/conf/pack.d/fd/space.c and locate the last two lines. Modify them in the
following way:
Change:
int fd_enable_FIFO = 0;
int fd_FIFOthresh = 0;
to:
int fd_enable_FIFO = 1;
int fd_FIFOthresh = 1;
Then relink the kernel and reboot the system.
