Improper SCSI Bus Termination
Ensure that only the last peripheral on the SCSI bus is terminated, see Chapter 7.
Some peripherals have a setting marked “Termination Power” instead of
“Terminator.” Ensure that termination power switches are set correctly.
Defective CD-ROM Disc
A fingerprint, contaminants, or deep scratches on the disc’s surface may
prevent the drive from reading data. Read Chapter 10 to learn how to clean
CD-ROM discs.
You should also review the low performance symptom discussed on page 60.
Conflict with a Network Card
Temporarily remove the network card and all related drivers from the
AUTOEXEC.BAT and CONFIG.SYS files. Reboot the computer and check that

Drive Not Terminated
If your CD-ROM drive is the only SCSI peripheral attached to your computer
or is the last SCSI peripheral in a daisy chain (i.e., a cable connecting multiple
SCSI peripherals to a single SCSI interface board), check that its termination
switch is ON. Always turn the drive power OFF before changing the setting of
the rear panel switches, Chapter 7.
