  • Page 23 PCI add-in card connect to one of these PIRQ signals. Some PCI interrupt sources are electrically tied together on the D845HV and D845WN boards and therefore share the same interrupt. Table 17 shows an example of how the PIRQ signals are routed on the D845HV and D845WN boards.
  • Page 24 ✏ NOTE In PIC mode, the Intel ICH2 can connect each PIRQ line internally to one of the IRQ signals (3, 4, 5, 6, 7, 9, 10, 11, 12,14, and 15). Typically, a device that does not share a PIRQ line will have a unique interrupt. However, in certain interrupt-constrained situations, it is possible for two or more of the PIRQ lines to be connected to the same IRQ signal.
