Table 17.
Note:
NOTE
In PIC mode, the ICH4 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. Refer to Table 16 for the
allocation of PIRQ lines to IRQ signals in APIC mode.
