5.4	SCO UNIX SYSTEM V/386 RELEASE 3.2 INSTALLATION

This installation procedure applies to SCO UNIX V/386 Release 3.2.0 and Release 3.2V2.0, SCO MPX Release 1.0.0 and Release 1.1.0. Different installation scripts for these releases is provided for easy installation.

The following is intended for use when installing the ULTRA 24F as a primary, bootable host adapter card.

Since the host adapter supports ISA mode (task file register compatible), the installation of the UNIX operating system is done in ISA mode. ISA mode is enabled through the configuration utility. Certain configuration options should be setup as follows for installing SCO UNIX.

.	Enable/Disable Host Adapter	:	Enable

.	BIOS Address Selection	:	C8000 or

CC000/D0000/D4000/	D8000/DC000

.	IRQ Selection	:	IRQ14

.	ISA Mode Selection	:	Primary

.	Drive Mapping Mode	:	16 HD/63 SCTR, 2 DRV

Other configuration options are user selectable.

Set the system CMOS drive type to type 1 for drive 0 and drive 1 if two SCSI hard disks are installed. The SCSI drives should be jumpered as SCSI ID 1 for drive 1 and ID 1 for drive 1. The 3rd and 4th SCSI drive can be any number other than 0 and 1 and host adapter SCSI ID, which is normally ID 7.

The installation procedure is the same as using a regular ISA disk controller (such as ULTRA 12F).

1.	Install the operating system normally, until the Basic Utilities and Extended Utilities have been installed. For the SCO MPX package, install the MPX package (use custom), until the system is running in the MPX operation (still in ISA disk controller mode).

2.	Reboot the system from UNIX. At this time the UNIX disk device driver still operates in the ISA mode. This can be verified by the device I/O location.

Device	Address	Vector

% disk	0x1F0 - 0x1F7	16

The following is the procedure to change the disk device driver to UltraStor's EISA disk device driver which allows running the host adapter in the EISA bus master mode.

1.	Login as a superuser (root)

2.	Change to tmp directory

# cd /tmp

3.	Insert the diskette labeled "ULTRA 24F EISA MSCSI Device Driver For SCO UNIX System V/386 Release 3.2." in drive A: and execute:

# tar xvf /dev/fd048ds9	(for 360 diskette)

or

# tar xvf /dev/fd0135ds9	(for 720 diskette)

Files 'Install", 'Driver.0', 'Remove' and 'Name' will be copied to the /tmp/3.2.0/tmp, /tmp3.2.2, /tmp/mpx.100 and /tmp/mpx.110 directories.

4.	Install and rebuild the UNIX kernel:

# cd 3.2.0	(for release 3.2.0)

or

# cd 3.2.2	(for release 3.2 V2.0)

or

# cd mpx.100	(for MPX release 1.0.0)

or

# cd mpx.110	(for MPX release 1.1.0)

# ./Install

5.	The kernel must be relinked to be able to use 'ad' device driver. Answer 'Y' to relink the kernel now, and 'Y' to boot the kernel by default, and 'N' to rebuild the kernel environment. The UltraStor MSCSI compatible device driver will be built into the kernel.

6.	After rebuilding the kernel, shutdown the system:

# shutdown

7.	IMPORTANT!! Reboot the system from a DOS bootable floppy and rerun the configuration utility again to disable ISA mode. The drive mapping mode and IRQ number should remain the same, except for MPX. (Note: for MPX package, change the interrupt to IRQ11). The CMOS drive type in the system setup should be changed to "NONE" or "Not Installed".

8.	After configuration is done, reboot the system. The host adapter will operate under EISA mode through the MSCSI interface.

Example:

Device	Address	Vector

% Adapter	0x 30O - 0x 33F 16	type=A id=7 ha=0

Tape	type=S ha=0 id=2 LUN=0	disk	type=S ha=0 id=0 LUN=0

Sdsk	Cyls= Hds= secs=

B.	The ULTRA 24F co-resides with a primary controller which connects to the bootable device.

The following procedure applies to the system that has primary controller with a bootable drive installed (such as ULTRA 12F with ESDI drive). The procedure adds UltraStor's EISA disk device driver (MSCSI) which allows running the host adapter in the EISA bus master mode. Configure the ULTRA 24F as the following:

.	Enable/Disable Host Adapter	:	Enable

.	BIOS Address Selection	:	Any address but has to be	higher than the primary con-	troller

.	IRQ Selection	:	Any IRQ but has to be differ-	ent from the primary con-	troller

.	Drive Mapping Mode	:	64 HD/32 SCTR, 2 DRV

1.	Login as a superuser (root)

2.	Change to tmp directory

# cd /tmp

3.	Insert the diskette labeled "ULTRA 24F EISA MSCSI Device Driver For SCO UNIX System V/386 Release 3.2." in drive A: and execute:

# tar xvf /dev/fd048ds9	(for 360K diskette)

or

# tar xvf /dev/fd0135ds9	(for 720K diskette)

Files "Install', 'Driver, 0', 'Remove' and 'Name' will be copied to the /tmp3.2.0 and /tmp/3.2.2 directories.

4.	Install and rebuild the UNIX kernel:

# cd 3.2.0	(for release 3.2.0)

or

# cd 3.2.2	(for release 3.2v2.0)

# cd mpx.100	(for mpx release 1.0.0)

# cd mpx.110	(for mpx release 1.1.0)

# ./Install

5.	Now, relink the kernel in order to use 'ad' device driver. Answer 'Y' to rebuild the kernel now, and 'Y' to boot the kernel by default, and 'N' to rebuild the kernel environment. The UltraStor MSCSI compatible device driver is now built into the kernel.

6.	After rebuilding the kernel, shutdown the system:
