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.
