After having explained the installation of the ICP Controller and the host-drives in chapters
B and C, we now explain how to install the operating system MS-DOS. By using some ex-
amples, we shall demonstrate how to partition a host-drive, transfer MS-DOS to the host-
drive, install Windows 3.x and use a CD-ROM drive (standing for any other
Not Direct Access
Device
) under MS-DOS. In addition, we will give you further information on how to install
Windows 95.

The structure of the Host Drives, which have been installed with GDTSETUP (in chapter C),
is not known to DOS. 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 DOS this Host Drive simply ap-
pears as one single SCSI hard disk with the capacity of the disk array. This complete trans-
parency represents the easiest way to operate disk arrays under DOS; neither DOS nor the
PCI computer need to be involved in the administration of these complex disk array con-
figurations.

You can partition the host-drives installed in chapter C with GDTSETUP as well as with the
MS-DOS program FDISK. However, in our explanation we shall only use GDTSETUP. For fur-
ther information on FDISK, please refer to your MS-DOS manual. During the following in-
stallation instructions we assume that there is not yet a boot disk in the computer system.
Therefore, the following steps aim at installing a
primary DOS partition
on the host-drive pre-
viously installed with GDTSETUP (see chapter C), activating this partition, and transferring
MS-DOS to this partition. Our objective is to be able to boot MS-DOS directly from this par-
tition at the end of the installation. First of all, we would like to draw your attention to a
common operating error which is often made when Host Drives are partitioned. Many users
ignore that an MS-DOS boot partition has to have the state
"active"
. If the partition is not
active, the system will attempt to boot MS-DOS, but will "hang" straight away. Very often,
the system message "ROM BASIC NOT FOUND, SYSTEM HALTED" is displayed (in the 40
lines of text mode). You can easily remedy this problem by booting the system from an MS-
DOS floppy disk, and then activating the partition with GDTSETUP (more information later
in this manual) or FDISK (for more information on FDISK please refer to the MSDOS user's
manual).
(A)
As already mentioned before, you can load GDTSETUP in two ways. For the partitioning,
GDTSETUP has to be loaded from disk under MS-DOS:
Boot the MS-DOS-operating system (either from a boot-floppy or from an already existing
boot drive, i.e., IDE-hard disk etc.).
(B)
In order for GDTSETUP to work properly, you have to load the device driver GDTX000
first. This can be done in two ways:
Load GDTX000 from the MS-DOS command level by typing in GDTX000<ENTER>, or
load GDTX000 automatically through the CONFIG.SYS file (DEVICE=GDTX000.EXE).
Load GDTSETUP from the MS-DOS command level by typing GDTSETUP<ENTER>.
