Fujitsu D1931 On board controller, AC97 USB 1,1 PCI slot, PCIe USB 2,0 SMBus Audio, AC97 HD Audio

Adding PCI cards

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:

											Controller or slot INT
					On board controller													Mechanical slot
																1	2			3		4		-	-		-
PCI												AC97 /
			USB 1,1									HD										PCI slot
INT																PCIe x16

Use first PCI/PCI Express slots that have a single 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 IRQ Line. The drivers of all cards and components on this IRQ Line must also support IRQ sharing.
