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#

1 2 ... 38 39 40 41 42 43 44 45 46 47 48 ... 82 83
