Pci Device Interrupt Map; Table 2-5 Pci Device Interrupt Mapping By The Bios - GE V7865 Series Hardware Reference Manual

2.5.3 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 ICH2. This mapping is illustrated in
Figure 2-1 on page 37 and is defined in Table 2-5.
The device PCI interrupt lines (INTA through INTD) that are present on each
device cannot be modified.
