PCI bus interrupts - Selecting correct PCI slot

Extensive information on this section is contained in the manual "Basic information on mainboard".

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

involved devices and their drivers must support IRQ sharing.

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

Monofunctional expansions cards

PCI/PCI Express 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.

Multifunctional expansion cards or expansion cards with integrated PCI-PCI bridge

These expansion cards require up to four PCI interrupts: INT A, INT B, INT C, INT D. How many and which of these interrupts are used is specified in the documentation provided with the card.

The assignment of the PCI interrupts to the IRQ Lines is shown in the following table:

Use first PCI/PCI Express slots that have a single PCI IRQ Line (no IRQ sharing). If you must use another PCI/PCI Express slot with IRQ sharing, check whether the expansion card properly supports IRQ sharing with the other devices on this PCI IRQ Line. The drivers of all cards and components on this PCI IRQ Line must also support IRQ sharing.
