PCI bus interrupts - Selecting correct PCI slot

To achieve optimum stability, performance and compatibility, avoid the multiple use of i ISA IRQs or PCI IRQ Lines (IRQ sharing). Should IRQ sharing be unavoidable, then all

involved devices and their drivers must support IRQ sharing.

PCI IRQ Lines connect AGP slots, PCI slots and onboard components to the interrupt controller. PCI IRQ Lines are permanently wired on the mainboard.

Which ISA IRQs are assigned to the PCI IRQ Lines is normally automatically specified by the BIOS (see description in "BIOS Setup").

Monofunctional expansions cards:

Standard AGP and PCI expansion cards require a maximum of one interrupt, which is called the PCI interrupt INT A. Expansion cards that do not require an interrupt can be installed in any desired slot.
