After having explained in chapters B and C the installation of the ICP Controller as well as
that of the Host Drives, we would now like to give you a few hints regarding the installation
of the operating systems
SCO UNIX V/386 3.2v4.x, 3.2v5.x (Open Server)
For successful installation, it is essential to read the SCO system manuals thoroughly.

The structure of the Host Drives, which have been installed with GDTSETUP (in chapter C),
is not known to UNIX. I.e., the operating system does not recognize that a given Host Drive
consists of a number of hard disks forming a disk array. To UNIX this Host Drive simply ap-
pears as one single hard disk with the capacity of the disk array. This complete transparen-
cy represents the easiest way to operate disk arrays under UNIX; neither UNIX nor the PCI
computer need to be involved in the administration of these complex disk array configura-
tions.

In the following description, we shall explain the installation of SCO UNIX V/386 3.2v4.x
and 3.2v5.x step by step in connection with the ICP Controller. Apart from the SCO UNIX
floppy disks and the SCO UNIX documentation, you also need the GDT floppy disks
GDT SCO UNIX BTLD-Disks for 3.2v4.x, 3.2v5.x
for the installation. In the following discussion, when we speak of a boot drive we refer to the
drive which is first integrated upon system power up. For the ICP Controller this drive is the
first Host Drive in the list of GDT Host Drives, i. e., the Host Drive number 0 (see
GDTSETUP menu
Configure Host-Drives ). During the installation you will have to decide whe-
ther you want the ICP Controller to make the boot drive available, or whether you want to
operate the ICP Controller as an additional controller in the computer system.
If the ICP Controller is the only hard disk controller in the computer system, it will automa-
tically make the boot drive available. If there are more hard disk controllers, the controller
which makes the first drive available (the drive containing the MS-DOS partition C:) will be
the boot controller.
In principle, SCO UNIX is always installed on the hard disk with Target ID 0 and LUN 0 on
host adapter 0, that is on Host Drive 0 of this controller. If SCO UNIX is installed from tape
(streamer) the streamer must have SCSI ID 2 and be connected to SCSI channel A of host
adapter 0. For an installation from CD-ROM, the CD-ROM device must have SCSI-ID 5 and
has to be connected with channel A of the ICP Controller.
