is enabled in the Configuration/Setup Utility program.
Note: On systems with a single IDE channel, only the primary channel can be
used.

v The correct device driver is installed for the CD-ROM drive.
If there is a diskette in the drive, verify that:

v The diskette is good and not damaged. (Try another diskette if you have one.)
v The diskette contains the necessary files to start the server.
