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 pins as follows:

Order 1 Order 2 Order 3 Order 4

PCI Slot 1 INT W# INT X# INT Y# INT Z#

PCI Slot 2 INT X# INT Y# INT Z# INT W#

PCI Slot 3 INT Y# INT Z# INT W# INT X#

Important

When adding or removing expansion cards, make sure that you unplug the

power supply first. Meanwhile, read the documentation for the expansion

card to configure any necessary hardware or software settings for the expan-

sion card, such as jumpers, switches or BIOS configuration.
