PCI Installation Tips
Some common PCI tips are listed here.
• Certain drivers may require interrupts that are not shared with other PCI drivers. The SSU can
be used to adjust the interrupt numbers for PCI devices. For certain drivers, it may be
necessary to alter settings so that interrupts are not shared.
• Check PCI interrupt interdependencies among slots and onboard devices.
