AT/ATX POWER MODE SELECT
The EITX-3000 supports two kinds of power modes: ATX (default)
and AT. The ATX mode requires a standby power connection and
a power supply on signal to turn on the main power supply. The
AT mode does not require a standby power connection but needs
to be connected to ground to boot up properly. The power mode
can be set by changing the jumper position on the 5-pin AT/ATX
pin header. Default setup support ATX mode.
