PCI Interrupt Request Routing
IRQ allows devices to 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# INT C# INT D#
PCI Slot 2 INT B# INT C# INT D# INT A#
PCI Slot 3 INT C# INT D# INT A# INT B#
ProSavage8 INT A#
AGP Slot INT A# INT B#
LAN RT8100BL INT B#
