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 "AGP/PCI/USB/AC97" IRQ pins are typically connected to the PCI
bus INTA#-INTD# pins as follows:
AGP
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#
PCI Slot 4 INT B# INT C# INT D# INT A#
PCI Slot 5 INT C# INT D# INT A# INT B#
