(Command Lines)
Command Line Options
The SYMCD.SYS device driver has several embedded functions available, which
are accessed via switches on the command line. An explanation of these options
follows. IMPORTANT: No spaces are allowed in specifying these command
line options. Spaces are required between different command line options.
Using the /ASK Option
This option prompts the user at initialization time whether to load SYMCD.SYS or
not. For example, the line in CONFIG.SYS that loads SYMCD.SYS would look
like this: DEVICE=C:[PATH]SYMCD.SYS /D:MY_CD /ASK
Using the /UPTOLUN= Option
This option is used to support multiple LUNs per Target ID on the SCSI bus. It is
needed to support CDROM changers that hold several CDs at one time, such as the
Pioneer DRM604x. For example, the line in CONFIG.SYS that loads SYMCD.SYS
would look like this:DEVICE=C:[PATH]SYMCD.SYS /D:MY_CD /UPTOLUN=x
where ‘x’ is in the range of 0 to 7. It uses LUN 0 through LUN x to assign a separate
drive letter for each of the x+1 CDs in the CD magazine. The SYMCD.SYS driver
defaults to supporting LUN 0 only.
Using the /NOBCD Option
This Option is used to support the Trantor Music Box CD audio application. Using
this option prevents the track numbers from being converted to BCD (Binary Coded
Decimal). If this option is used with CD audio applications such as Adaptec’s cdplayer,
Corel’s cd-audio, or Future Domain’s cdaudio, track numbers >16 are not reported
correctly because these applications require binary track numbers. For example, the
line in CONFIG.SYS that loads SYMCD.SYS would look like this:
DEVICE=C:[PATH]SYMCD.SYS /NOBCD
Troubleshooting
THE CD-ROM DRIVE IS NOT SEEN AT BOOT TIME, OR THE SYSTEM
LOCKS UP
a. Make sure the required drivers are installed and in the correct sequence.
b. Make sure the driver’s CONFIG.SYS line has the correct path to the driver.
c. Make sure MSCDEX, in the AUTOEXEC.BAT, has the same drive name as
the CDROM driver in the CONFIG.SYS file.
d. Make sure there is no ID or drive letter designation conflict.
e. Power down all units in the system.
f. Check the cable and power connections.
g. Make sure the SCSI bus is properly terminated.
h. Make sure sufficient drive letters are specified (through the MS-DOS lastdrive=
command) to include your CD-ROM. A CD-ROM which uses multiple disks
requires a letter for each disk.
