POST beep codes

problem.
v One beep indicates the successful completion of POST.
v More than one beep indicates that POST detected a problem. For more
information, see “Beep symptoms” on page 97
POST error messages
POST error messages occur during startup when POST finds a problem with the
hardware or detects a change in the hardware configuration. For a list of POST
errors, see “POST error codes” on page 110
Event/error logs

the system generated during POST. The System Event/Error Log contains all error
messages issued during POST and all system status messages from the Advanced

(see “Starting the Configuration/Setup Utility program” on page 33); then, select
Event/Error Logs from the main menu.
