We distinguish two cases.
a.) No ICP Controller has been configured for UnixWare yet .
In this case, the GDT driver must be installed from the GDT UnixWare BTLD-Disk by means
of the UnixWare desktop and the options "System Setup", "Application Setup". Alternative-
ly, this procedure can be carried out from the UnixWare shell: "
pkgadd -d /dev/dsk/f0t " (GDT
driver disk in drive 0).
b.) A ICP Controller has already been configured for UnixWare.
In this case, you only have to add an additional entry for the new ICP Controller. This is car-
ried out by
/etc/scsi/pdiadd -d DRQ -v IRQ -m MEM gdth
for DRQ use 0 (not necessary for PCI boards), for IRQ write the IRQ number the ICP Con-
troller uses. MEM corresponds with the DPMEM address of the ICP Controller (which is
displayed in the BIOS message of the ICP Controller after power up). In both cases, you
have to carry out a cold boot in order to use the new ICP Controller under UnixWare.
Example: /etc/scsi/pdiadd -d 0 -v 12 -m c8000 gdth.
After that, a reboot of the UnixWare system is necessary. No kernel link is required because
the driver will be dynamically loaded.

The host adapter number assigned to the ICP Controller is derived from the PCI slot num-
ber of the ICP Controller. Therefore, if there is only one ICP Controller installed in the PCI
bus computer system, the host adapter number=0. If there are two ICP Controllers instal-
led, the ICP Controller with the lower PCI Slot number is assigned host adapter number 0
and the ICP Controller with the higher PCI slot number is assigned host adapter 1. (Note:
After a cold boot, the GDT BIOS displays a couple of messages, each beginning with the
controller’s PCI slot number, e.g. "[PCI 0/3] 4 MB RAM detected". The number after the ‘/’ is
the slot number of the controller. This helps you to determine which is the order of the ICP
Controllers and and which host adapter number is assigned to them by UNIX. See also
chapter B, Hardware Installation).

Target-IDs and LUNs for “Not Direct Access Devices“ (devices like streamers, tapes and
CD-ROMs and therefore not configurable via GDTSETUP), are directly assigned to the SCSI-
ID and the channel of the ICP Controller. Host Drives are assigned in increasing order to
the free coordinates (bus number and target ID;LUN is always 0).

In the PCI computer are two ICP Controllers (HA 0 = 1st GDT, HA 1 = 2nd GDT), each with
two SCSI channels.
1 hard disk
as Host Drive no. 0 on HA0
1 hard disk as Host Drive no. 0 on HA1
1 hard disk as Host Drive no. 1 on HA1
1 Streamer SCSI-ID 2, LUN 0 on SCSI channel A of HA0
1 CD-ROM SCSI-ID 3, LUN 0 on SCSI channel B of HA0
1 DAT SCSI-ID 2, LUN 0 on SCSI channel A of HA1
