Troubleshooting Your System
Troubleshooting IRQ Assignment Conflicts
Most PCI devices can share an IRQ with another device, but they cannot use an IRQ simultaneously. To
avoid this type of conflict, see the documentation for each PCI device for specific IRQ requirements.
Table 4-2 lists the IRQ assignments.
Troubleshooting External Connections
Loose or improperly connected cables are the most likely source of problems for the system, monitor, and
other peripherals (such as a printer, keyboard, mouse, or other external device). Ensure that all external
cables are securely attached to the external connectors on your system. See Figure 1-2 for the back-panel
connectors on your system.
