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 INT A# ~ INT D# pins as follows:
Order 1
Order 2
Order 3
Order 4
PCI Slot 1
INT B#
INT C#
INT D#
INT A#
PCI Slot 2
INT C#
INT D#
INT A#
INT B#
PCI Slot 3
INT D#
INT A#
INT B#
INT C#
