INSTALLATION GUIDE FOR THE SDMS SCO UNIX OPENSERVER BTLD DRIVER V4.11.00
This file describes the features and use of the SDMS device driver for the
SCO OpenServer 5 operating system environments. These instructions assume that
you are using a Symbios host adapter and appropriate SCSI devices. You only need
to "link" the new SDMS device driver if you have a LSI Logic host adapter in
the system. Go to the Troubleshooting section for further information about
installation to an IDE Hard Drive.

2) Within the text instructions for adding SCSI disk drives, tape drives,
and CD-ROM drives, the system prompts the user to check whether the
driver is the default value or enter the exact driver name. The
package name and the driver name are slha.
******************************* Introduction ********************************
SCO UNIX is the first UNIX operating system licensed for IBM-compatible
microcomputers. The integrated communications, file system, international
application support, and documentation create an ideal platform for those
requiring a full-featured, UNIX-based operating system. SCO UNIX takes full
advantage of the capabilities of the 80386 and above microprocessors.
To connect SCSI devices to one or more host adapters, you must place the
proper host adapter driver in the SCO UNIX kernel. The SDMS Boot Time
Loadable Driver (BTLD) diskette contains one package:
slha contains the driver for SCO OpenServer 5
You must link-edit the proper driver into the SCO UNIX kernel. The kernel must
reside on the boot drive: either an internal, non-SCSI hard drive (for
example, IDE), or a SCSI hard drive attached to host adapter 0 with SCSI ID 0
and LUN 0. The BTLD permits an easy installation of SCO UNIX OpenServer 5 with
the software provided by The Santa Cruz Operation.
SCO OpenServer 5 provides only one installation diskette, labeled Boot
Disk. This diskette, along with the SDMS BTLD driver diskette, and other
software media, are used during an SCO OpenServer 5 installation.
The slha driver allows SCO OpenServer 5 operating systems to interface with
SCSI devices connected to the LSI Logic SYM53C8XX or SYM53C1XXX family of
chipsets and/or LSI Logic 8XX host adapter cards. Driver 4.11.00 features
support for the Ultra160 SYM53C1010 chipset and Ultra160 SYM8955U Host
Adapter board. Both the 33 MHz and the 66 MHz chips are supported.
The following sections provide instructions for configuring the SCO UNIX kernel
with the SDMS driver, installing SCO UNIX onto a hard drive, and adding SCSI
peripheral devices. These instructions assume that you are familiar with UNIX
system administration.
* * * * * * * * * * * * Features * * * * * * * * * * *
The BTLD driver supports these features:
o Easy UNIX installation on a hard disk with the SDMS Boot Time Loadable
Driver (BTLD) diskette
o Ultra160 Data Transfers (for SYM53C1010 devices)
o Ultra160 Domain Validation
o Wide and synchronous negotiation (including Fast SCSI/Ultra SCSI/

* * * * * * * * * * * * Description * * * * * * * * * *
UNIX installation on a SCSI system requires creation of a SCO UNIX kernel
that contains the SCSI driver to support SCSI devices. The two possible
installation procedures are:
1. Installing UNIX and the proper SDMS BTLD driver for the first time on
a boot drive.
2. Loading or updating the proper SDMS BTLD driver on a boot drive.
* * * Procedure 1: New System Installation * * *
To perform a new SCO UNIX installation that includes the proper SDMS driver,
then follow this procedure. Procedure 1 uses a Boot Time Loadable Driver
(BTLD) to provide a user-friendly method for installing SCO UNIX onto a
hard disk drive.
* * * Procedure 2: Existing System Installation * * *
To attach SCSI devices to a Symbios host adapter while using a non-SCSI hard
drive (for example, IDE) as the boot hard drive already containing a SCO UNIX
system, execution of Procedure 2 is all that is necessary. This procedure
installs the SDMS driver on the non-SCSI boot drive. Some of the SCSI devices
supported include tape drives, CD-ROM drives, and SCSI hard disk drives used as
secondary storage. This procedure is also followed to replace a previously
installed SDMS driver on a SCSI boot drive.
Each procedure is described in detail below. LSI Logic recommends that you
complete the entire installation in one session. To complete this installation
without interruption, you should have sufficient time (possibly over an hour).
************************ Installing the SCO UNIX Driver *********************
* * * * * * Procedure 1: New System Installation * * * * * * *
This procedure installs SCO UNIX onto a hard disk drive. This installation is
necessary to build a new UNIX kernel that includes your SDMS driver. During
installation, you are given the option of retaining current partitions on
the root hard disk. For instance, you could have a DOS partition or a user
UNIX partition already established on the drive. For more details on UNIX
installation, refer to the SCO OpenServer Handbook.
1. Link the SDMS BTLD into the UNIX kernel during installation.
a. Insert the SCO UNIX installation diskette and reboot the system. For
SCO OpenServer 5, this diskette is labeled Boot Disk.
b. At the "boot:" prompt (prompt appears without the double qoutes), type:
link
Press Enter.
c. At the next prompt, type:
slha
Do not remove the diskette. Press Enter.
d. When prompted during the installation, insert either the proper
installation diskette or the SDMS BTLD diskette, and press Enter.
The system may prompt you to enter a routine:
"Please enter
which routine (0-40) to replace '?' to list),
'a' to add "slhainit" at the end [default],
'n' to do nothing, or 'q' to quit"
Enter the indicated routine number that precedes this message.
Then, the system may prompt with another inquiry:
"Please enter
which routine (0-2) to replace '?' to list),
'a' to add "slhapoll" at the end [default],
'n' to do nothing, or 'q' to quit"
Enter the indicated routine number that precedes this message.
e. Continue the installation according to the SCO UNIX documentation.
f. The SCO OpenServer 5 system automatically creates a file unix.safe
during installation. To access this UNIX kernel, type after the "boot:"
prompt:
unix.safe
2. Install SCSI device support.
3. Continue from Procedure 2, step 3.
************************ Installing the SCO UNIX Driver *********************
* * * * * * Procedure 2: Existing System Installation * * * * *
This procedure assumes SCO UNIX is already installed on a hard disk drive.

* * * * * * * * * * * Troubleshooting * * * * * * * * * *
The following conditions should exist after a successful installation:
The directory etc/conf/sdevice.d should contain a file named slha. This file
contains the sdevice entries.
The directory etc/conf/cf.d contains files sdevice, mdevice, and mscsi. Files
sdev.hdr and mdev.hdr describe the values of the possible field entries
in the files sdevice and mdevice, respectively.
The sdevice file should contain a slha entry for each LSI Logic host
adapter configured in the system.
The second field in the sdevice file should read 'Y'.
A slha entry should appear in the mdevice file.
A slha entry for each configured SCSI device should appear in the
mscsi file.
Directory /etc/conf/pack.d/slha should exist and contain the files Driver.o
and space.c.
Some potential problems and their suggested solutions are:
* * * Problem * * *
Loading the SCO UNIX kernel to an IDE hard drive
* * * Solution * * *
You only need to "link" if you have a SCSI device attached to a LSI Logic host
adapter. Follow the instructions in the SCO UNIX Installation documentation.
Once the installation has completed, then go to Step 2 in Procedure 2 and use
"installpkg" to install your SDMS driver.
* * * Problem * * *
A SCSI device is not found.
* * * Solution * * *
a. Reboot and press Cntl C when prompted to view the SCSI BIOS Configuration
Utility displays.
b. Verify the device is on the correct host adapter and ID. If the device is
not shown, then it is probaby turned off or a cabling problem exists.
* * * Problem * * *
UNIX system behaves unreliably after a configuration change.
* * * Solution * * *
Whenever the hardware or software configuration is altered, you must rebuild
the kernel. Use the directory /etc/conf/cf.d and type:
./link_unix
to rebuild the kernel.
* * * Problem * * *
An error message occurs during the rebuild of the kernel.
* * * Solution * * *
Reinstall the proper SDMS driver using the installpkg utility.
Remember to relink the kernel and then reboot the system.
* * * Problem * * *
The root disk is not found or the partitioning of the disk fails.
* * * Solution * * *
If your boot drive is a SCSI disk, use the SCSI BIOS Configuration Utility
to check that the disk is assigned SCSI ID 0 (zero) and is configured to host
adapter 0 (zero), LUN 0 (zero).
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
