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 setup, 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#). Monofunctional 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.
