This motherboard provides
one 8-pin ATX 12V power
connector.
This 4-pin connector is used
to provide a cabled baseboard
or front panel connection for
value added features and 3rd-
party add-in cards, such as
Emergency Management cards,
that provide management
features using the IPMB.
This COM header supports a
serial port module.
This allows you to clear the
data in CMOS. To clear CMOS,
take out the CMOS battery and
short the Clear CMOS Pad.
