6.5.5 Troubleshooting
Some potential problems and their suggested solutions are:
The CD-ROM drive is not seen at boot time, or the system locks up.
•
Make sure the required drivers are installed and in the correct
sequence.
•
Make sure the drivers’ entries in the CONFIG.SYS file have the correct
path to the driver.
•
Make sure MSCDEX.EXE , in the AUTOEXEC.BAT , has the same drive
name as the CD-ROM driver in the CONFIG.SYS file.
•
Make sure there is no ID or drive letter designation conflict.
•
Power down all units in the system.
•
Check the cable and power connections.
•
Make sure the SCSI bus is properly terminated.
Table 6.3 SYMCD.SYS Command Line Options
Option Name Description
/ASK Prompts you at initialization time whether to load SYMCD.SYS or not. For example, the
line in the CONFIG.SYS file that loads SYMCD.SYS would look like this:
DEVICE=C:[PATH]SYMCD.SYS /D:MY_CD /ASK
/UPTOLUN Changes the default for multiple LUNs per Target ID on the SCSI bus. The current
default is to scan all LUNs. CD-ROM changers that use multiple LUNs work by default.
To turn off scanning all LUNs on a SCSI bus, choose / UPTOLUN=0 . This saves some
time during boot.
/NOBCD Supports 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 cd-player, Corel’s cd-audio, or
Future Domain’s cd-audio, track numbers >16 are not reported correctly because
these applications require binary track numbers.
For example, the line in the CONFIG.SYS file that loads SYMCD.SYS would look like this:
DEVICE=C:[PATH]SYMCD.SYS /NOBCD
