POST error messages and codes
The table below lists POST error codes and their associated messages.
The BIOS prompts the user to press a key in case of serious errors.
Some of the error messages are preceded by the string "Error" to
highlight the fact that these indicate a system that might be
malfunctioning. All POST errors and warnings are logged in the system
event log.
