BIOS POST Codes
Typically, the BIOS displays warning or error messages on the video display in the
event of hardware or configuration errors.
However, if the error is so severe that the BIOS halts immediately or cannot initialize
the video, you can read the last executed POST code from the port 80 LED.
The port 80 LED is located on the motherboard (see
FIGURE B-1). The BIOS POST
codes are listed in
TABLE B-1.
