Question: I see some of my PCI devices sharing IRQs, but the sys-
tem seems to be fine. Is this correct or not?
Answer: Some PCI Bus Mastering devices can share IRQs without perfor-
mance penalties. These devices are designed to work correctly while shar-
ing IRQs. See Table 3-1, below, for details on shared IRQs.
Table 3-1. P4SDA+/P4SDM Shared IRQs
PCI 1 shares an IRQ with AC97, CNR and the System Management bus
PCI 2 has a dedicated IRQ (does not share)
PCI 3 shares an IRQ with USB controller #1 (USB0 & USB1)
PCI 4 has a dedicated IRQ (does not share)*
PCI 5 has a dedicated IRQ (does not share)*
PCI 6 shares an IRQ with USB controller #2 (USB2 & USB3)*

device(s)?
Answer: The 80-wire/40-pin high-density ATA100/66 IDE cable that came
with your system has two connectors to support two drives. This special
cable must be used to take advantage of the speed the ATA100/66 technol-
ogy offers. Connect the blue connector to the onboard IDE header
and the other connector(s) to your hard drive(s). Consult the docu-
mentation that came with your disk drive for details on actual jumper loca-
tions and settings.
