INSTALLING EXPANSION CARDS
This outlines the procedure for adding expansion cards to your Mainboard. Remember to
read the documentation for your expansion cards and make the necessary hardware and
software setting changes (i.e. jumper settings).
The Mainboard features two (2) PCI-32 (32-bit, 33MHz) slots, one (1) PCI-64 (64-bit,
66/33MHz) slot and two (2) PCI-X (100/133MHz) slots to accommodate PCI expansion
cards.
1. Remove the bracket plate on the slot you intend to use. Keep the bracket for possible
future use.
2. Insert the PCI card into the correct slot on the Mainboard, pushing down with your
thumbs evenly on both sides of the card.
3. Secure the card on the slot with the screw you removed above.
4. Assign IRQs for PCI expansion card: An IRQ number is automatically assigned to PCI
expansion card. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI
slot that contains a card requiring an IRQ.
WARNING
Completely power OFF your power supply when adding or removing any expansion
cards or other system components. Failure to do so may cause severe damage to both
your Mainboard and expansion cards.
