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 optional
SCSI hard drive activity LED connector.
