Troubleshooting

The SCSI subsystem stops working.

If the SCSI subsystem should stop working, do the following:

1.Review the Troubleshooting Checklist and "Mass Storage Guidelines" in Chapter 2 before you continue.

2.Run DiagTools. Verify that the SCSI ID and other switch settings are correct and get specific information or verification that the problem is the SCSI bus.

3.If an accessory board was added recently, check if there is a resource conflict between the new board and an existing accessory board. Also, if you have changed the options on an existing board, there may be a resource conflict.

a.Remove the new board and restart the computer. If this corrects the problem, the board is either defective or it is trying to use a system resource used by the SCSI subsystem.

b.Check if the board is using memory, I/O addresses, or interrupt lines that are also used by the SCSI subsystem.

4.Check to see if there have been recent changes to any software. For example, has anyone moved, removed, or changed the configuration files or drivers? Refer to the software documentation for more information.

5.Check the SCSI cables for problems that may have been caused by recent computer maintenance, hardware upgrades, or physical damage.

6.If you suspect hardware failure and there are no system error messages, check each component associated with the failure. Equipment failure is probably the most unlikely reason for a SCSI subsystem failure.

7.Check the ROM BIOS version associated with the SCSI controller to make sure it is the most recently issued version.

Video/Monitor Problems

Symptoms:

Nothing is displayed on the monitor.

The monitor is blank and the computer beeps.

The wrong size characters appear on the monitor.

Colors are wrong or there are no colors on the monitor.

If you installed a video board and are not using the built-in video system, go to Step 12.

If you have two video monitors connected, test the monitors to make sure they are working (Step 1-4) then go to Step 10.

NOTE

The system BIOS will beep if no video hardware is detected. This happens when the

 

on-board video is disabled and there is no video adapter board installed.

1.Review the Troubleshooting Checklist before you continue.

2.Check the contrast and brightness controls to make sure they are adjusted.

3.Verify the video and power cords are connected to the monitor.

4.Make sure there is adequate power:
