PCI bus interrupts - Selecting correct PCI slot

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

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 devices used 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

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:

On board controller

PCI INT LINE

USB 1.1

USB 2.0

SMBus

HD Audio

LAN

Mechanical Slot

PCI INT LINE

PCIe x16

PCIe x1

PCI 1

PCI 2

PCI 3

PCI 4

First use 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.
