4. Install Expansion Cards

WARNING! Unplug your power supply before adding or removing expansion
cards or other system components. Failure to do so may cause severe damage to
both your motherboard and expansion cards.
First read your expansion card documentation for hardware and software settings
that may be required to set up your specific card.

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 pos-
sible 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 a standard design, 16 IRQs are available, but
most of them are already in use, leaving 6 free for expansion cards.
