CMOS Clear
JBT1 is not actually a jumper but consists of two contact pads. To clear the contents
of CMOS, short these pads together by touching them both with a metal conductor
such as the head of a small screwdriver. JBT1 is located near the SATA header
on the P8SCT. Note: for ATX power supplies, you must completely shut down the
system and remove the AC power cord before clearing CMOS.
2-7 Jumper Settings
Explanation of
Jumpers
To modify the operation of the moth-
erboard, 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 identiļ¬ 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.
