PCI Express x1 Slot
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 Slots
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.
