(GDTSETUP menu option Configure Host Drives ). Now you can start the installation procedu-
re. During installation, a GDT driver corresponding to the IRQ used by the ICP Controller
has to be selected. As discussed in chapter B of this user’s manual, the PCI System BIOS
automatically assigns an IRQ to a PCI INT. The IRQ used by a ICP Controller is displayed by
the GDT BIOS after a cold boot. After having successfully installed the basic Interactive sy-
stem, use
InstallPkg to install the software package OS File Management, kernel Configuration ,
and afterwards the GDT driver software. After having installed other desired software, choo-
se the menu option
kconfig to configure the ICP Controller as boot controller and to enter
any other device connected to it. Then, a new kernel must be linked and installed (see abo-
ve). After
Exit and a system reboot, you can partition and mount Host Drives with sysadm
(see above). You can integrate the GDT driver into the kernel of the copy of the boot disks
in two different ways:
a) There is already a bootable system on another computer
In this case, the easiest method is to install the driver software for the ICP Controller on
this system and to link a kernel containing the ICP Controller as boot controller (see abo-
ve). Then copy this kernel to the Interactive boot disk copy. This can be easily done since
this floppy disk contains a mountable file system. You can then start the installation with
this boot disk. Make sure that the controller's IRQ is set according to the entry in
kconfig .
b) There is no bootable system available.
For Interactive UNIX 3.2v4, only.
When using this UNIX version, you have to use the GDT Interactive disk called GDT Interac-
tive UNIX 3.2v4 - for boot installation. The installation is carried out according to the Inter-
active UNIX 3.2v4 documentation.

Target-IDs 0 and 1 with LUN 0 to 7 are reserved for "Direct Access Devices" (devices beha-
ving like a hard disk or a removable hard disk and therefore configurable with GDTSETUP).
There is a fixed correlation between the Host Drive number in GDTSETUP (menu "Configure
Host Drives") and the target-ID and LUN. When a host-drive has been installed with
GDTSETUP, it has to be communicated to the UNIX system (in
kconfig ) by assigning a tar-
get-ID and LUN which are determined with the following formula:
Host-Drive Number = 8 * Target-ID + LUN
The host-drive number is the number the drive has in the list of available host drives in the
GDTSETUP program. The following exemplary screen shows a list of host drives in which
two host drives are installed.
