EISA Bus Problems Indicated at Power-Up
Table 4–11 Troubleshooting EISA Problems
Step Action
1 Confirm that the EISA module and any cabling are
properly seated.
2 Run the ECU as described in Chapter 3 to:
• Confirm that the system has been configured with the
most recently installed controller.
• See what the hardware jumper and switch setting
should be for each ISA controller.
• See what the software setting should be for each ISA
and EISA controller.
• See if the ECU deactivated (<>) any controllers to
prevent conflict.
• See if any controllers are locked (!), which limits the
ECU’s ability to change resource assignments.
3 Confirm that hardware jumpers and switches on ISA
controllers reflect the settings indicated by the ECU.
Start with the last ISA module installed.
4 Check for a bad slot by moving the last installed controller
to a different slot.
5 Call option manufacturer or Digital customer support for
help.
