Standard Features 41
PCI Device
Interrupt Map
The PCI bus-based external devices include the PMC sites, Ethernet controller
and the PCI-to-VME bridge. The default BIOS maps these external devices to the
PCI Interrupt Request (PIRQx) lines of the ICH. This mapping is illustrated in
Figure 2-1 on page 42 and is defined in Table 2-5.
