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:
PCI Slot 1
PCI Slot 2
PCI Slot 3
2-28
Order 1 Order 2
INT B# INT C#
INT C# INT D#
INT D# INT A#
Order 3 Order 4
INT D# INT A#
INT A# INT B#
INT B# INT C#
