PCI Bus Problems
PCI bus problems at startup are usually indicated by the inability of the system
to detect the PCI device. Use Table 9-6 to diagnose the likely cause of the
problem.

Troubleshooting PCI Bus Problems
Step Action
1 Confirm that the PCI option card is supported, and confirm firmware and
software versions.
2 Confirm that the PCI option card and any cabling are properly seated.
3 Check for a bad slot by moving the last installed PCI controller to a
different slot.
4 Call the option manufacturer or your service representative for help.
Some PCI devices do not implement PCI parity, and some have a parity-
generating scheme that may not comply with the PCI specification. In such
cases, the device functions properly as long as parity is not checked.
