POST Error Codes and Messages
The following table defines POST error codes and their associated messages. The BIOS prompts the user to press a key in case of serious errors. Some error messages are preceded by the word "Error" to highlight the fact that the system might be malfunctioning. All POST errors and warnings are logged in the System Event Log, unless the System Event Log is full.
