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:

DEVICE Interrupt ID Select REQ / GNT

XGI Z7 PCI_PIRQ # 0 PCI_AD18

IT8213F PCI_PIRQ # 2 PCI_AD19 PCI_REQ# 2 / PCI_GNT# 2

PCI Slot 1 PCI_PIRQ # 0 PCI_AD20 PCI_REQ# 0 / PCI_GNT# 0

PCI_PIRQ # 1

PCI_PIRQ # 2

PCI_PIRQ # 3

PCI Slot 2 PCI_PIRQ # 3 PCI_AD21 PCI_REQ# 1 / PCI_GNT# 1

PCI_PIRQ # 0

PCI_PIRQ # 1

PCI_PIRQ # 2

PCI Slot 3 PCI_PIRQ # 2 PCI_AD22 PCI_REQ# 3 / PCI_GNT# 3

PCI_PIRQ # 3 or

PCI_PIRQ # 0 ARBITER_REQ# 1

PCI_PIRQ # 1 ARBITER_GNT# 1

PCI Slot 4 PCI_PIRQ # 1 PCI_AD23 ARBITER_REQ# 2

PCI_PIRQ # 2 &

PCI_PIRQ # 3 ARBITER_GNT# 2

PCI_PIRQ # 0
