Refer to Table 2-25 for the jumper
settings to clear CMOS. 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 use JBT1 to clear
CMOS. Replace JBT1 back to the pin 1-2 posi-
tion before powering up the system again. Do
not use the PW_ON connector to clear CMOS.

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 identified with a
square solder pad on the printed cir-
cuit board. See the motherboard
layout pages for jumper locations.
