In order to be able to install Windows 3.x, a fully operational MS-DOS operating system has
to be present on the chosen partition. Furthermore, the first entry in the CONFIG.SYS file
behind the HIMEM.SYS line has to be:
DEVICE=GDTX000.EXE
(if necessary, add the correct path name after the "=" symbol and before GDTX000.EXE).
(A)
Now install Windows according to the instructions given in the Windows manual. Gen-
erally, you start with
Disk 1 - Setup
from which you load the setup program. This Setup pro-
gram guides you through the entire installation and prompts you to insert further floppy
disks.
(B)
After the installation is completed, the Setup program will ask you if you want to reset
the system. This reset must be performed.
(C)
If you change to the directory WINDOWS after the reset and type in WIN<ENTER>, Win-
dows will be loaded. Although thanks to its high computing power, the ICP Controller is just
right for disk intensive operating systems such as Windows, it will not show its full capacity
yet. The reason for this is that the "communication" between Windows and the ICP Con-
troller is not yet carried out by GDTX000.EXE, but by Windows' SMARTDRV driver.
(D)
The steps in this section aim at removing SMARTDRV from the CONFIG.SYS and AUTO-
EXEC.BAT files, and at adding a few entries to the Windows initialization file SYSTEM.INI.
Now, delete those lines from the CONFIG.SYS and AUTOEXEC.BAT files which contain
SMARTDRV.EXE (one line in each file) using an editor such as EDIT for instance which is
part of MS-DOS 5 and 6, or deactivate these lines by entering REM at their beginning. Then
save and exit the files. Next, load the SYSTEM.INI file located in the WINDOWS directory
into the editor and look for the entry
[386Enh]
. The following lines have to be inserted after
this entry:
[386Enh]
EMMExclude=D000-D1FF
(or according GDT DPMEM area)
VirtualHDIrq=off
DMABufferSize=128
Now save the file. In the line "EMMexclude=..." you have to enter the address area occupied
by the GDT DPMEM.
(E)
Now do a warm reboot in order for the changes in the CONFIG.SYS the AUTOEXEC.BAT
file to take effect.
(F)
Now, change to the WINDOWS directory and type in WIN<ENTER>; Windows is loaded
again and the installation is completed.

CD-ROM drives (as well as tape streamers, WORM drives and most MOD drives, too) belong
to the category of the so-called
Not Direct Access Devices
. They
