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:

DEVICE	MCP1 INT Pin	IDSEL	CLOCK	REQ# / GNT#
PCI Slot	PIRQA	AD17	PCICLK 0	REQ#0 / GNT#0
Mini PCI Slot	PIRQB	AD18	PCICLK 1	REQ#1 / GNT#1

LAN1	PIRQC	AD21	CLKLAN 1	REQ#2 / GNT#2

LAN2	PIRQD	AD22	CLKLAN 2	REQ#3 / GNT#3
