5-10 Jumper Settings

Explanation of Jumpers

To modify the operation of the mother-

board, jumpers can be used to choose

between optional settings. Jumpers

create shorts between two pins to

change the function of the connector.

Pin 1 is identied with a square solder

pad on the printed circuit board. See

the motherboard layout pages for

jumper locations.

Note: On a two-pin jumper, "Closed"

means the jumper is on both pins and

"Open" means the jumper is either on

only one pin or completely removed.

Clear CMOS (JBT1)

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads

to prevent accidental clearing of CMOS. To clear CMOS, use a metal object such

as a small screwdriver to touch both pads at the same time to short the connec-

tion. Always remove the AC power cord from the system before clearing CMOS.

Note: For an ATX power supply, you must completely shut down the

system, remove the AC power cord and then short JBT1 to clear CMOS.
