Clear CMOS and Disable ME Jumper Setting (J4): It
is for clearing the CMOS memory and system setup
parameters by erasing the data stored in the CMOS
RAM such as the system passwords. The ME_disable
setting allows updating the Intel Management
Engine firmware through software without a
electronic programmer. The Intel ME's leverage of
non-volatile storage prevents users from removing
critical inventory, remote control, or virus protection
agents.
To clear CMOS, disconnect AC power supply. Set the
jumper to 4-6 and wait a minute to be sure the
CMOS has been cleared. Then return the CMOS
jumper to it's original position.Restore power to the
system.

Hardware or Software Reset Jumper(J3): The jumper can
be adjusted to be in either hardware or software reset
mode when the reset switch is pressed. The hardware
reset will reboot the system without turning off the
power. The software reset can be programmed to
reset a software to its default setting.
ATX Power Connector(ATX1, ATX2): Find the proper
orientation when inserting the plugs, for the supply
plugs are designed to fit these connectors in only one
orientation.
