Hardware Setup
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 F#
INT G#
INT H#
INT E#
PCI Slot 2
INT G#
INT H#
INT E#
INT F#
PCI Slot 3
INT A#
INT B#
INT C#
INT D#
