2.6 PCI Device Interrupt Map

32 VMIVME-7805/VME-7805RC Hardware Reference Manual
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 33 and is defined in Table 2-5.
The device PCI interrupt lines (INTA through INTH) that are present on each
device cannot be modified.
