PCI Bus Resources

PCI Slots

The following table shows an overview of the PCI slots:

PCI slot

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.
