2-8-3 PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line, 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:
IMPORTANT!
If install PCI card on shared PCI slot, make sure that the PCI
card driver supports “Shared IRQ” or the card doesn’t need IRQ
assignment. Otherwise, conflicts will arise between two PCI
groups that will make the system unstable or the PCI card
inoperable.
