CMOS Clear
JBT1 is not literally a jumper but con-
sists 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 between the FPUSB4/5(J21)
and Chassis Intrusion(J25) headers
on the motherboard. For ATX/SSI
power supplies, you must completely
shut down the system and remove
the AC power cord before clearing
CMOS.
