PCI bus interrupts - Selecting correct PCI slot
PCI bus interrupts - Selecting
correct PCI slot
Extensive information on this section i s 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). S hould IRQ sharing be unavoidable,
then all invo lved devices and their drivers must support IRQ sharing.
Which ISA IRQs are assigned to the P CI IRQ Lines is normally automatically specified
by the BIOS (see "BIOS Setup" description).
Monofunctional expansion 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. Ho w many and
which of these interrupts are used is specified in the documentation provided with the card.
The assignment of the PC I interrupts to the IRQ Lines is show n in the following table:
