To achieve optimum stability, performance and compatibility, avoid the multiple use of 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.
