Installation Guide for SDMS UnixWare 7 Driver Version 4.24.00.
This file describes the features and use of the SDMS Device Driver for the
SCO UnixWare 7 operating system environment. This driver is referred to as
"C8XX".
Note: Use only driver version 4.24.00 for UnixWare 7. If you need support
for UnixWare 2.1.x, use driver version 4.08.00. If you need support
for UnixWare 2.0.X, use driver version 3.02.00. Either of these
drivers can be obtained from LSI Logic's website located at
www.lsilogic.com.

******************************* Introduction ********************************
UnixWare 7 extends the Unix SVR4.2 operating system. UnixWare features
include a graphical user interface (GUI), networking, application
compatibility, multitasking capability, and multi-user capability
Additionally, UnixWare provides multiprocessor support.
The C8XX driver allows SCO UnixWare operating systems to interface with
SCSI devices connected to the Symbios SYM53C8XX and SYM53C1XXX family of
chipsets and/or Symbios 8XX/1XX host adapter cards. Driver 4.24.00 features
support for the Ultra160 SYM53C1010 chipset and the associated host adapter
boards.
The following sections describe the procedures to install the driver during a
first time installation of UnixWare, and to update a previously installed
UnixWare with this C8XX driver.
* * * * * * * * * * * * Features * * * * * * * * * * *
The C8XX driver supports these features:
o Ultra160 Data Transfers (for SYM53C1010)
o Domain Validation
o Parallel Protocol Request (PPR) negotiation to SCSI-3 devices for
Ultra160 Double Transition <DT> data transmission
o Easy installation using UnixWare tools
o Wide and synchronous negotiation (including Fast SCSI/Ultra SCSI/
Ultra2 SCSI)
o Multiple host adapters
o Disconnect/Reselect
o Multiple and non-contiguous Logical Unit Numbers (LUNs) support
o Dynamic interrupt mapping
o Scatter/Gather
o Wide SCSI
o SCSI pass-through functionality
o Tagged command queuing
o Multiprocessor support
o Target-initiated negotiation
o NVRAM and NVS Configuration data areas
o Termination Control using NVRAM and NVS settings
* * * * * * * * * Symbios Devices Supported * * * * * * * *

based on those devices:
o SYM53C810, SYM53C810A, SYM53C810AE (SYM8100S, SYM8100ASP, SYM20810)
o SYM53C815 (SYM815XS, SYM8150SP)

o SYM53C875, SYM53C875E (SYM8750SP, SYM8751SP, SYM8751SPE, SYM8751D)
o SYM53C876 (SYM22801, SYM22802)
o SYM53C885
o SYM53C895, (SYM8951U, SYM8952U)
o SYM53C895A (SYM8953U)
o SYM53C896 (SYM22910, SYM21002, SYM22902)
o SYM53C1010 (SYM8955U, SYM21040)

The C8XX driver for SCO UnixWare operating systems is available on a
3.5 inch floppy diskette labeled PCI SCSI SCO UnixWare. Use this diskette to
load the driver during the installation of the operating system, or to
access the devices on the SCSI bus after a UnixWare installation. The
following sections describe these procedures.
The installation media kit includes a host adapter diskette. This diskette
also contains a bundled C8XX driver. If you have both a C8XX diskette
directly from LSI Logic and the host adapter diskette from the media kit,
use the latest release of the C8XX driver by inserting its diskette first
when host adapter diskettes are requested during installation.
******************* Installing the SDMS UnixWare C8XX Driver ****************
This section provides new and existing system installation instructions.
* * * * * * * * * New System Installation * * * * * * * * *
1. Boot the computer using the Install diskettes delivered with the UnixWare
Operating System media kit. UnixWare 7 has two diskettes.
2. Follow the instructions on the screen.
3. Insert the PCI SCSI SCO UnixWare driver diskette when prompted to insert a
host adapter diskette.
To install other host adapter drivers, then insert the host adapter diskette
provided with the UnixWare media kit when requested. If there are no other
host adapter drivers to install, continue the installation.
The system loads the required drivers, such as C8XX, and indicates when
they are loaded. At the end of the installation, you will see a prompt to
reinsert the HBA driver diskette.
4. Insert the PCI SCSI SCO UnixWare driver diskette and press Enter.
The kernel will be built and the installation will terminate.
6. Remove the driver diskette when prompted to do so and reboot the system.
* * * * * * * * * Existing System Installation * * * * * * * *
* * * Adding or Updating the C8XX Package * * *
Before you install the C8XX driver, make a backup copy of the existing
kernel:
1. Log on as root.
2. At the shell prompt type:
cp /stand/unix /stand/unix.safe
Use this copy of the old kernel to reboot the system if the driver
installation fails. Refer to the section titled Troubleshooting for
more information if necessary.
3. Once the old kernel is saved, insert the PCI SCSI SCO UnixWare driver
diskette.
4. Load the driver using the pkgadd command by typing:
pkgadd -d diskette1
5. Select the C8XX package.
The C8XX driver on this diskette is then loaded onto the system.
The system will again prompt you to load a driver even if loading was
successful.
6. Type q (quit) and press Enter.
7. Verify that the driver is now loaded successfully by typing:
pkginfo c8xx
8. The package information should look like this:
system c8xx Symbios IHV HBA
After the C8XX package is loaded, a message indicating a system reboot
is necessary may appear.
9. To reboot, type this command:
init 6
During the boot process, the driver scans the SCSI bus and lists the devices
found on it. If the kernel panics during boot, then reboot the system with
the saved copy of the old kernel. Booting from the saved copy of the kernel
is described in the next section titled Troubleshooting. If the reboot
is successful, the system is ready to use.

* * * Problem * * *
Driver Installation Fails.
* * * Solution * * *
To utilize the unix.safe kernel file that was created before installing the
C8XX host adapter driver, follow these steps.
1. Reboot the system.
2. Wait for the UnixWare 7 Logo screen to appear, then press the
space bar to begin an interactive boot session.
3. When the interactive boot prompt appears, type:
boot unix.safe
The UnixWare 7 Logo screen will reappear. The system will then boot
from the UNIX kernel specified above.
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.
