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 & LAN” 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#

LAN INT B#

1 2 ... 31 32 33 34 35 36 37 38 39 40 41 ... 79 80
