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 identified 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.
