Description
CDROM.SYS is needed whenever a CD-ROM device is connected
on the SCSI bus. It must be loaded in conjunction with Microsoft’s
CD-ROM Extension 2.21 or above (MSCDEX.EXE). Because
CDROM.SYS communicates with the SCSI BIOS through
MINICAM.SYS or DOSCAM.SYS, so one of these drivers must
be loaded to use CDROM.SYS.
Installation
1. Use the COPY command to copy the appropriate driver from
the SDMS SCSI Drivers disk to your boot disk.
2. Add CDROM.SYS to your CONFIG.SYS file. It goes in after
MINICAM.SYS or DOSCAM.SYS and SCSIDISK.SYS (if
these drivers are also being used), in this order:
DEVICE=C:<PATH>MINICAM.SYS
DEVICE=C:<PATH>SCSIDISK.SYS
DEVICE=C:<PATH>CDROM.SYS /D:NAME
Note:
The /D: is not a drive letter designation; it indicates the
name you wish assigned to your CD-ROM. The NAME
must be included, and can be any combination of up to
8 characters.
3. To ensure that sufficient drive letters are available to identify all
devices connected to the SCSI bus, add the MS-DOS LAST
DRlVE command to the CONFIG.SYS file:
LASTDRIVE=x
With x specifying a drive letter in the range C through Z. The
letter assigned to LASTDRIVE represents the last valid drive
MS-DOS is able to recognize and also represents the maximum
number of drives available. For example, LASTDRIVE=K
allows access to eleven (11) logical drives. For further details
about LASTDRIVE, consult your MS-DOS manual.
