Boot error messages 
During startup (the boot process), the BIOS first performs a Power On Self Test (POST) and 
checks whether certain functional units of the PC are operating error-free. When an error 
occurs within this phase, the BIOS outputs a tone sequence (beep code) based on the 
current test result. The boot sequence is interrupted immediately if fatal errors occur.  
If the POST does not return an error, the BIOS initializes and tests further functional units. In 
this startup phase, the graphics controller is initialized and any error messages are output to 
the screen.  
The following lists the error messages from the system BIOS. For information on error 
messages output by the operating system or programs, refer to the corresponding manuals.
