Error Messages and Indicators

Port 80h POST Codes

During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O

port 80h. If the POST fails, execution stops and the last POST code generated is left

at port 80h and displayed on the Desktop Board’s seven-segment LED display shown

in Figure 31. This code is useful for determining the point where an e

rror occurred

during the POST.
