information for MSCDEX. As mentioned before, it is our objective to be able to access the
CD-ROM drive with a drive name (i.e. E). Naturally, this drive name has to be "free", and
there have to be enough drive names available. For example, the DOS command
LASTDRIVE=H would enable the user to use drive names from A to H. In the
AUTOEXEC.BAT file, the Microsoft translation program for CD-ROMs (MSCDEX - Microsoft
CD-ROM Extension) is loaded. It is not part of MS-DOS (except for version 6). The para-
meter /D:CD-ROM set here has to be identical to the parameter set after the ASPICD mod-
ule in the CONFIG.SYS file. After a warm reboot which serves to activate the changes made
in the CONFIG.SYS and AUTOEXEC.BAT files, the CD-ROM drive can be accessed as drive E
(in our example there are two SCSI hard disks in the PCI computer, and under MS-DOS they
are accessed as C and D). Drive E can be accessed under Windows, too, now (the Icon next
to "E" indicates that it is a CD-ROM drive).

When using the corelSCSI software, the installation is carried out by a program (install) so
that the changes in the files CONFIG.SYS and AUTOEXEC.BAT mentioned below are, to a
large extent, made automatically. Under corelSCSI the SCSI/FAST-SCSI channels of the ICP
Controller are available as independent host adapters. The important lines in both files are
printed bold.
CONFIG.SYS
device=c:\windows\himem.sys
device=gdtx000.exe
files=30
buffers=30
stacks=9,256
dos=high,umb
shell=\COMMAND.COM /E:512 /P
device=\dos\setver.exe
device=\gdt\gdtaspi.exe
device=c:\corel\cuni_asp.sys /ID:6 /HAN:0 /N:1 /D:MSCD000
lastdrive=h
AUTOEXEC.BAT
path=c:\;c:\dos;c:\gdt;c:\aspi;
prompt $P -$G
c:\corel\corelcdx /M:8 /D:MSCD000
The first line following the HIMEM.SYS command of the CONFIG.SYS file loads the
GDTX000.EXE. The next line loads the GDT ASPI Manager GDTASPI.EXE. Next, the corel
ASPI Module for the CD-ROM drive is loaded. The parameter "/D:MSCD000" has nothing to
do with a drive name, it only serves as recognition information for CORELCDX. As men-
tioned before, it is our objective to be able to access the CD-ROM drive with a drive name
(i.e., E). Naturally, this drive name has to be "free", and there has to be enough drive names
available. For example, the command LASTDRIVE=H would enable the user to use drive
names from A to H under DOS. In the AUTOEXEC.BAT file, the corel translation program
for CD-ROMs, CORELCDX, is loaded. The parameter /D:MSCD000 set here has to be identi-
cal to the parameter set after the ASPI Module in the CONFIG.SYS file. After a warm reboot
which serves to activate the changes made in the CONFIG.SYS and AUTOEXEC.BAT files,
the CD-ROM drive can be accessed as drive E (in our example there are two SCSI hard disks
in the PCI computer, and under MS-DOS they are accessed as C and D). Drive E can be ac-
cessed under Windows, too, now (the Icon next to "E" indicates that it is a CD-ROM drive).
Information on the various CD-ROM drives which can be used can be obtained directly
from Corel.
