Troubleshooting
Diskette Drive Problems Action
Diskette drive In-Use
light stays on, or the
system bypasses the
diskette drive. If there is a diskette in the drive, verify that:
1. The diskette is good and not damaged. (Try
another diskette if you have one.)
2. The diskette is inserted correctly (label up and
metal-shutter end first) in the drive.
3. The diskette contains the necessary files to start the
system.
4. The system is not in Secure mode.
5. The diskette drive is enabled (check the drive
startup sequence setting in the Setup program).
6. Your software program is OK (see the Software
Problems troubleshooting chart provided later in
this section).
7. Your drive startup sequence is set correctly (check
the Boot Sequence setting in the Setup program).
If the diskette drive In-Use light stays on, or the system
continues to bypass the diskette drive, have the system
serviced.
Monitor Self-Tests Action
Some IBM monitors have their own self-tests. If you
suspect a problem with your monitor, refer to the
information that comes with the monitor for adjusting
and testing instructions.
If you still cannot find the problem, have the monitor
and system serviced.
