PCI Interrupt Request Routing

The IRQ, abbreviation 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 INT A# ~ INT D# pins as follows:

	Order 1	Order 2	Order 3	Order 4
PCI Slot 1	INT A#	INT B#	INTC#	INTD#

PCI Slot 2	INT B#	INTC#	INTD#	INT A#

PCI Slot 3	INTC#	INTD#	INT A#	INT B#
