6.Run the System Set Test Group in the system diagnostics.
See Chapter 5, “Running the System Diagnostics.” Do the tests complete successfully?
Yes. Continue to step 7. No. Go to step 12.
7.Turn off the system, disconnect it from AC power, and remove the computer cover.
8.Reinstall one of the expansion cards you removed in step 3, repeat steps 4 and 5, and continue with step 9.
9.Replace the computer cover, and reconnect the system to AC power.
10.Run the System Set Test Group again. Do the tests complete successfully?
Yes. Continue to step 11. No. Go to step 12.
11.Repeat steps 7, 8, 9, and 10 for each of the remaining expansion cards you removed in step 3.
Have you reinstalled all of the expansion cards with- out encountering a test failure?
Yes. Continue to step 12.
No. The expansion card is faulty. See Chapter 11, “Getting Help,” for instructions on obtaining tech- nical assistance.
12.Disconnect the keyboard and reboot the system.
NOTE: You may receive a keyboard error message because the keyboard is not connected.
Does the system boot successfully? Yes. Continue to step 13.
No. Go to step 14.
13.Swap the keyboard with a comparable working keyboard, and run the System Set Test Group again.
Do the tests complete successfully? Yes. You have fixed the problem. No. Continue to step 14.
14.See Chapter 11, “Getting Help,” for instructions on obtaining technical assistance.
Troubleshooting the Diskette Drive Subsystem
If the monitor displays a system error message indicating a diskette drive problem during execution of either the boot routine or the system diagnostics, the problem may be caused by any of the following conditions:
•The system configuration settings do not match the physical diskette subsystem configuration.
•The diskette drive cables are not properly connected or are faulty.
•An expansion card is interfering with proper drive operations.
•A diskette drive may be improperly configured.
•The diskette drive or tape drive is faulty.
•The computer’s power supply is not providing suffi- cient power for the drives.
•The computer’s diskette drive logic is faulty.
The troubleshooting procedures for the diskette drive subsystem are divided into the following subsections:
•“Checking the Diskette Drive Subsystem”
•“Troubleshooting the Diskette Drive Subsystem”
•“Troubleshooting a SCSI Tape Drive”
Before you begin the troubleshooting procedures, com- plete steps 1 and 2 in the next subsection, “Checking the Diskette Drive Subsystem,” to verify that the system con- figuration information is correct for the installed diskette drive(s).
If, after completing these steps, the system boots cor- rectly and the monitor no longer displays a system error message, the problem is resolved. If you continue to have problems, however, proceed with the appropriate diskette drive subsystem troubleshooting procedure.
