III. INSTALLATION
4. Expansion Cards
First read your expansion card documentation on any hardware and software set-
tings that may be required to set up your specific card.
NOTE: PCI Slot 5 has a MediaBus extension, which allows the installation of either
a PCI card or a MediaBus card (optional multifunctional card).
WARNING! Unplug your power supply when adding or removing expansion
cards or other system components. Failure to do so may cause severe damage to
both your baseboard and expansion cards.
Expansion Card Installation Procedure
1. Read the documentation for your expansion card.
2. Set any necessary jumpers on your expansion card.
3. Remove your computer system’s cover.
4. Remove the bracket on the slot you intend to use. Keep the bracket for possible
future use.
5. Carefully align the card’s connectors and press firmly.
6. Secure the card on the slot with the screw you removed in step 4.
7. Replace the computer system’s cover.
8. Set up the BIOS if necessary (such as IRQ xx Used By ISA: Yes in PNP AND
PCI SETUP)
9. Install the necessary software drivers for your expansion card.
Assigning IRQs for Expansion Cards
IMPORTANT: PCI Slots 4 & 5 share the same IRQ. If using PCI cards on both
slots 4 & 5, make sure that the drivers support “Share IRQ” or that one card does not
need an IRQ assignment. Conflicts will arise on PCI Slots 4 & 5 that will make the
system unstable.
Some expansion cards need to use an IRQ to operate. Generally an IRQ must be
exclusively assigned to one use. In a standard design there are 16 IRQs available but
most of them are already in use, leaving 6 IRQs free for expansion cards.
Both ISA and PCI expansion cards may require to use IRQs. System IRQs are avail-
able to cards installed in the ISA expansion bus first, then any remaining IRQs are
available to PCI cards. Currently, there are two types of ISA cards. The original ISA
expansion card design, now referred to as legacy ISA cards, requires that you con-
figure the card’s jumpers manually and then install it in any available slot on the ISA
