Monofunctional expansions cards
Standard AGP and PCI 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 the first PCI slots that have a single PCI IRQ Line (no IRQ sharing). If you must use another PCI
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.
