During power-up self test (POST), most system BIOSes write status codes to I/O port 80h or 84h.
A POST code display shows the last value written to this port as a hexadecimal number (e.g. 1B) on a LED display.
If the POST code remains blank, the system BIOS is not coming up at all. Something is seriously wrong with the system board.
The meaning of individual POST codes is specific to each BIOS and system vendor, and should be obtained from them.
BIOS Central has a very complete collection of POST code tables.
