2.8.3.2.1

Reset Switch Connector

Pins 5 and 7 can be connected to a momentary (SPST type) switch that is normally open.

When

the switch is closed, the board resets and runs the POST.

2.8.3.2.2

Hard Drive Activity LED Connector

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.

For the LED to function properly, an IDE drive must be connected to

the onboard IDE interface.

The LED will also show activity for devices connected to the SCSI

hard drive activity LED connector.
