PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor. The PCI IRQ
pins are typically connected to the PCI bus pins as follows:
32-bit PCI Slot
PCI Express x16 Slot
Mini PCI-E Slot
DEVICE INT Pin IDSEL CLOCK REQ# / GNT#
32-bit PCI Slot PIRQA AD17 PCICLK 0 REQ#0 / GNT#0
32-bit PCI Riser PIRQC AD18 PCICLK 1 REQ#1 / GNT#1
32-bit PCI Riser PIRQD AD19 PCICLK 2 REQ#2 / GNT#2
