Diagnostic LEDs

The BIOS sends a 1-byte hex code to port 80 prior to each POST task. These codes are
displayed on four tri-colored LEDs, located on the system board and available at the back
of the server chassis, and can provide troubleshooting information in the event of a system
hang during POST.
