This motherboard supports
four Mini Cool Edge IO x8
Connectors. Please connect
these connectors to the HDD
backplane board.
Please connect PCIE SSDs to
the connector.
The header is used for the SM

This allows you to clear the
data in CMOS. To clear CMOS,
take out the CMOS battery and
short the Clear CMOS Pad.
PSU SMBus monitors the
status of the power supply, fan
and system temperature.
