Adding PCI cards
A26361-D1527-Z120-1-6319 English - 21
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 PCI IRQ Lines is shown in the following table.

Use the first PCI slots that have an unsplitted PCI IRQ Line. 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.
Ensure that you insert the battery the right way round. The plus pole must be on the top!
