Please connect the thermal
sensor cable to either pin 1-2
or pin 2-3 and the other end to
the device which you wish to
monitor its temperature.
This allows you to clear the
data in CMOS. To clear CMOS,
take out the CMOS battery and
short the Clear CMOS Pad.
This 4-pin connector is used
for the front LAN status
indicator.
The onboard NCSI header is
used for external connections.
This header is used for PWM
configurations.
