1. INSTALLING SCO UNIX 3.2.4
----------------------------------
* UNIX installation on a SCSI system requires that a copy of SCO UNIX be
  created that contains the device drivers to support SCSI devices. The
  installation of UNIX depends on how the SCSI device will be configured.
  There are two possible installation procedures:

  (1) Install UNIX and the SCSI device drivers on a SCSI boot drive.
      See Procedure 1.

  (2) Install UNIX and the SCSI device drivers on a non-SCSI boot drive.
      See Procedure 2.	


Procedure 1
----------------------------------
* This procedure will install UNIX on a SCSI hard disk drive. This 
  installation is necessary to build a new UNIX kernel that includes the
  NCR SCSI device drivers. With the BTLD, it is not necessary to create a
  new SCSI N1 disk. The basic steps for accomplishing this are outlined below.
  Further detail on UNIX installation can be found in the SCO UNIX system
  Administrator's Reference manual.

  (1) Insert the SCO UNIX N1 installation disk and boot the system.

  (2) At the Boot: prompt, type:
  	link
      @ress "Enter".

  (3) At the next prompt type:
  	bscam
      Do not remove the N1 diskette. Press "Enter"

  (4) At the next prompt, replace the N1 diskette with the SCO SDMS SCSI
      Drivers diskette (which contains the BTLD), and press Enter.

      When using the BTLD to install UNIX, the "cam3" tool is automatically
      installed.

  (5) Continue from this point as a normal installation according to the SCO
      UNIX.

  Note: If a SCSI tape drive is used in the initial installation, the SCSI
        tape drive ID should be set to "2", and it should be confifured to
	path 0, LUN 0.

	The ID of the tape drive should not conflict with a SCSI hard disk ID.

Procedure 2
----------------------------------
* This procedure assumes UNIX is already installed on an IDE, ESDI, or ST506
  hard disk drive. It will show how to include the device drivers needed to
  access SCSI devices installed after the non-SCSI drive. This installation
  is necessary to build a new UNIX kernel which includes the NCR SCSI device
  drivers. The basic steps for accomplishing this are outline below. Further
  detail on UNIX installation can be found in the SCO UNIX System
  Administator's Reference manual.

  (1) NCR recommands creating a second copy of UNIX.
      Log in as root and issue the command:

      	cp /unix /unix.good

      This creates a second copy of UNIX under the name /unix.good.
      If any problems arise with the Kernel being built in UNIX, this
      procedure ensures that a valid copy of UNIX will be available.

  (2) Install the NCR SDMS SCSI UNIX device drivers.

      a. Insert the SCO SDMS SCSI Drivers floppy diskette in the drive and
         type:

	 	installpkg

	 Press the "ENTER" key to contine.

      b. A prompt will appear to insert the requested floppy diskette. Since
         the NCR diskette has already been inserted, press "ENTER" key to
	 continue.

      c. A prompt will then ask for the name of the package. Type:

      		cam3

	 Press the "ENTER" key to contine.

      d. To execute CAM3, remove the NCR floppy diskette from the drive, then
         type:

	 	mkdev cam3

	 Press the "ENTER" key to contine.


      e. Follow the menu displayed to add SCSI hard drive, tape drive or
	 SCSI CD-ROM drive to UNIX, and rebuilding the kernel.

      f. To activate the new kernel the system must be rebooted.
