At this point we presume that the CDROM drive has been properly connected to the ICP
Controller. This includes that the SCSI-ID and the SCSI bus terminators are set in accor-
dance with the settings of the already existing SCSI devices (i. e., the SCSI-ID chosen for the
CDROM drive is not occupied by another device; resistor terminators are located only at
the two ends of the SCSI bus).

The GDTX000.EXE driver is loaded from the first line following the HIMEM.SYS command
of the CONFIG.SYS file. Loading the SETVER driver (part of MS-DOS) allows older versions
of Microsoft's CDROM translation program MSCDEX (loaded from AUTOEXEC.BAT) to run
trouble-free with the MS-DOS version currently installed. The next line loads the ICP ASPI
Manager GDTASPI.EXE. Next, the ASPICD module for the CDROM drive is loaded. The pa-
rameter "/D:CDROM" has nothing to do with a drive name, it only serves as a recognition
information for MSCDEX. As mentioned before, it is our objective to be able to access the
CDROM 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 CDROMs (MSCDEX - Microsoft
CDROM Extension) is loaded. It is not part of MS-DOS (except for version 6). The parameter
/D:CDROM set here has to be identical to the parameter set after the ASPICD 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 CDROM 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 CDROM drive).
D.5.2 Example: Using corelSCSI for the CDROM
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.
