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 PCI IRQ Lines is shown in the following table:

		Onboard controller
PCI INT
		USB 1,1					AC97				PCI slot
LINE
		1st	2nd	3rd	USB	SM	Audio	Modem	LAN	Graphic	1	2	3
					2,0	Bus
1	(A)	A	-	-	-	-	-	-	-	A	-	-	-
2	(B)	-	-	-	-	A	A	A	-	-	A	-	-
3	(C)	-	-	A	-	-	-	-	-	-	B	A	-
4	(D)	-	A	-	-	-	-	-	-	-	C	B	A
5	(E)	-	-	-	-	-	-	-	-	-	D	C	B
6	(F)	-	-	-	-	-	-	-	-	-	-	D	C
7	(G)	-	-	-	-	-	-	-	-	-	-	-	D
8	(H)	-	-	-	A	-	-	-	A	-	-	-	-

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.

Replacing lithium battery

In order to permanently save the system information, a lithium battery is installed to provide the CMOS-memory with a current. A corresponding error message notifies the user when the charge is too low or the battery is empty. The lithium battery must then be replaced.

!	Incorrect replacement of the lithium battery may lead to a risk of explosion!
	The lithium battery may be replaced only with an identical battery or with a type
	recommended by the manufacturer.
	Do not throw lithium batteries into the household waste. They must be disposed of in
	accordance with local regulations concerning special waste.
	Make sure that you insert the battery the right way round. The plus pole must be on the
	top!
