III. INSTALLATION

(Expansion Cards)

4.  Expansion Cards

WARNING:  Make sure that you 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 motherboard and expansion cards.

IMPORTANT:  This motherboard requires a Riser card in order to add expansion
cards.  Insert the Riser card provided by your retailer into the Riser slot with the
notch over the safety tab.  The Riser card cannot be inserted in the wrong orientation
because of the safety tab.  The following is an example only.  Your riser card may
look different.  Check your system manual for specific settings that may be needed.

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. Setup 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

Some expansion cards need to use an IRQ to operate.  Generally an IRQ must be
exclusively assigned to one use.  In an standard design there are 16 IRQs available
but most of them are already in use by parts of the system which leaves 6 free for
expansion cards.
