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.

This file is divided into the following sections:

Read the information below before proceeding with the installation instructions.

       1) The 4.11.00 slha driver supports all of the OpenServer 5 releases of 
	  SCO UNIX (Releases 5.0.0, 5.0.2, 5.0.4, 5.0.5 and 5.0.6).
       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 *  *  *  *  *  *  *  *  *  *  *

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. 
This installation is necessary to build a new UNIX kernel that includes the 
proper Symbios host adapter driver. The basic steps for accomplishing 
this task are outlined below. For more details on UNIX installation, refer to
the SCO UNIX System Administrator's Reference Manual.

1. 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. Installing the SDMS driver

   a. Insert the SDMS BTLD diskette in the drive and type: 

      installpkg

      Press Enter to continue.

      A prompt appears to insert the requested diskette, which has  
      already been inserted.

   b. Press Enter.

      A prompt now asks for the name of the package. 

   c. Type:

      slha

      Press Enter to continue.

   d. If a driver is already present from a previous installation, a prompt 
      inquires about replacing it. Reply y for yes. 

   e. Once the install package (installpkg) has completed, relink the kernel by
      typing:

      /etc/conf/cf.d/link_unix

      at the command prompt.

   f. The system executes the command and then prompts for a series of 
      responses to:

      1.  Do you want this kernel to boot by default (y/n)?

          Type: y  

          Press Enter. 

          The system backs up the old kernel.

      2.  Do you want the kernel environment rebuilt (y/n)? 

          Type: y 

          Press Enter.

   g. Reboot the system to activate the new kernel by typing at the command 
      prompt:

      reboot

      Press Enter.

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

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.
