I. Using UnixWare
After having exposed the installation of the ICP Controller as well as that of the Host Drives
in chapters B and C, we would now like to give you some hints and pieces of advice on how
to install the operating system UnixWare version 2.x and UnixWare 7. The required ICP disk
can be created from the ICP System CDROM.
I.1 Transparency of Host Drives
The structure of the Host Drives, which have been installed with ICPCON (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
appears as one single hard disk with the capacity of the disk array. This complete transpar-
ency 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 con-
figurations.
I.2 General Installation Notes
In the following description, we shall explain the installation of UnixWare in connection
with the ICP Controller step by step. Apart from the UnixWare floppy disks, the CD-ROM
and the UnixWare documentation, you also need the ICP floppy disk (can be created from
the ICP System CDROM):
UnixWare BTLD-Disk
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 ICP Host Drives, i. e. the Host Drive with number 0 (see ICPCON menu Configure
Host-Drives). During the installation you will have to decide whether you want the ICP Con-
troller 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 automatically make the boot drive available.
If there are more hard disk controllers, the controller which makes the first drive (the drive
containing the MS-DOS partition C:) available will be the boot controller. If the ICP Con-
troller does not make the boot drive, you can skip the following paragraph.
I.3 ICP Controller as Boot Controller
There must be a Host Drive on the first ICP Controller found during a cold boot. In addi-
tion, the ICP BIOS must be enabled and the SCSI-ID of the corresponding ICP SCSI channel
must be set to 7.
Now you can begin the installation. Boot the system with the first UnixWare boot disk.
UnixWare scans the system for host adapters. When requested insert the UnixWare BTLD-
Disk. The installation procedure which follows then has to be carried out as described in the
UnixWare documentation.
Important note: As already mentioned in chapter B "Hardware Installation", the assignment
of an IRQ to an INT is made by the PCI System BIOS. The UnixWare versions 2.xy and higher
automatically recognize the IRQ of a PCI expansion card.
