PCI IRQ Line X - Assignment of the PCI Interrupts

PCI IRQ Line x defines which ISA interrupts are used for the separate PCI slots.
If you select Auto in the BIOS set up, the interrupts are assigned automatically and no further
settings are required.
Multifunctional PCI boards or boards with an integrated PCI-to-PCI bridge can use several PCI
interrupts (INTA#, INTB#, INTC#, INTD#). Mono-functional PCI boards (default) only use one PCI
interrupt (INTA#) per PCI slot.
The PCI interrupts INTA#, INTB#, INTC# and INTD# are available for every PCI slot.
The same interrupt can be assigned simultaneously to several PCI boards. You should avoid this
condition due to reduced performance.
If you use a setting other than Auto, the Plug & Play functionality of the system BIOS for the
corresponding PCI boards is deactivated.
Auto The PCI interrupts are assigned automatically in accordance with the Plug & Play
guidelines.
Disabled No ISA interrupt is assigned to the PCI interrupt.
3, 4, 5, 7, 10, 11, 12, 14, 15
The selected ISA interrupt is assigned to the PCI interrupt. You may not select an
ISA interrupt that is used by a component on the system board (e.g. controller) or an
ISA board.
