4.1.1.1.1 Hard Drive Activity LED Header
Pins 1 and 3 can be connected to an LED to provide a visual indicator that data is being read from
or written to a hard drive. Proper LED function requires a SATA hard drive or optical drive
connected to an onboard SATA connector.

Pins 5 and 7 can be connected to a momentary single pole, single throw (SPST) type switch that is
normally open. When the switch is closed, the board resets and runs the POST.
