SYMCD.SYS Driver Features
• Compatible with Microsoft’s CD-ROM Extension 2.21 and above
• Multi-session Photo CD support
• Support for reading CCDA disks
Description
SYMCD.SYS is needed whenever a CD-ROM device is connected on the SCSI bus.
You must load it in conjunction with Microsoft’s CD-ROM Extension 2.21 or above
(MSCDEX.EXE). SYMCD.SYS communicates through ASPI8XX.SYS, so you must
load ASPI8XX.SYS to use SYMCD.SYS.
Installing Your SYMCD.SYS Driver
1. Use the COPY command to copy the appropriate driver(s) from the SDMS
SCSI Drivers disk to your boot disk.
2. Add SYMCD.SYS to your CONFIG.SYS file. It goes in after ASPI8XX.SYS
and SYMDISK.SYS (if this driver is also being used), in this order:
DEVICE=C:[PATH]ASPI8XX.SYS
DEVICE=C:[PATH]SYMDISK.SYS
DEVICE=C:[PATH]SYMCD.SYS /D:NAME
NOTE: The /D: is not a drive letter designation; it indicates the name you wish
assigned to your CD-ROM. You must include the NAME, which can use any
combination of up to 8 characters.
3. To insure that sufficient drive letters are available to identify all devices con-
nected to the SCSI bus, add the MS-DOS LASTDRIVE 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.
4. Unless your CD-ROM access software specifies otherwise, Microsoft’s CD-
ROM Extension (MSCDEX.EXE) should execute from the AUTOEXEC.BAT
file in order to access your drive. Add the following line to your
AUTOEXEC.BAT file: [PATH]MSCDEX /D:NAME
For example, if: DEVICE=C:[PATH]SYMCD.SYS /D:MY_CD is in
CONFIG.SYS, then:[PATH]MSCDEX /D:MY_CD should exist in the
AUTOEXEC.BAT file.
5. Check installation instructions for the CD-ROM drive itself for other param-
eters necessary to include with MSCDEX.
6. When MSCDEX is loaded during the AUTOEXEC.BAT file execution, a mes-
sage is returned assigning a drive letter to the CD-ROM drive. For example:
DRIVE E = DRIVER MY_CD UNIT 0
This informs you that the CD-ROM drive is recognized and ready for use.
