(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>,

Windows 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 ca-

pacity yet. The reason for this is that the "communication" between Windows and the ICP

Controller 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 af-

ter 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) be-

long to the category of the so-called Not Direct Access Devices. They

cannot

be installed

with GDTSETUP or FDISK and FORMAT and they are not directly supported by MS-DOS or

Windows - unlike, for example, hard disks and removable hard disks. To install and access

these devices, a special standard, the so-called ASPI Standard (Advanced SCSI program-

ming Interface), has been created. While the manufacturer of the controller (in this case

ICP) has to offer the ASPI Manager, the manufacturer of the SCSI device (CD-ROMs etc.)

has to provide an ASPI Module (note: there are some companies which have specialized in

the development of ASPI modules, for example Corel Corp. with its product

corelSCSI

; the

ICP Controller is certified by Corel). Both units, the SCSI controller and the SCSI device,

communicate through this ASPI interface. It is not a hardware interface (like, for example,

Centronics, SCSI or RS232), but a pure software interface.

The following illustration explains this interface:
