JP25 is used to select the method of powering on the system. If you want the system to pow-
er on whenever AC power comes in, set the jumper pins 2 and 3 to "On." If you want to use
the power button, set pins 1 and 2 to "On."
When using the "Power-On" feature to power the system back on after a power failure occurs,
the system may not power on if the power loss is resumed within 5 seconds (power flicker).
