PCI Express x1 Slots
There are two PCI Express x1 slots that are designed to accommodate less
bandwidth-intensive cards, such as a modem or LAN card. The x1 slot provides
250 MB/sec bandwidth.
PCI Express x16 Slot
There is one PCI Express x16 slot that is reserved for a graphics or video card.
The bandwidth of the x16 slot is up to 4GB/sec (8GB/sec concurrent).
When installing a PCI Express x16 card, be sure the retention clip snaps and
locks the card into place. If the card is not seated properly, it could cause a
short across the pins. Secure the card’s metal bracket to the chassis back panel
with the screw used to hold the blank cover.
Jumper Settings
The motherboard contains a 3-pin BIOS configuration jumper that enables all
board configurations to be done in the BIOS Setup program.
The silk screen on the motherboard shows a ∆ next to pin 1.
Clear CMOS Jumper: CLR_CMOS
The motherboard uses the CMOS RAM to store all the set parameters. The
CMOS can be cleared by removing the CMOS jumper.
Use the following procedure to clear CMOS:
1. Turn off the AC power supply and connect pins 1 and 2 together using the
jumper cap.
2. Return the jumper setting to normal (pins 2 and
3. Together with the jumper cap).
4. Turn the AC power supply back on.
