Auto-booting.................... 
One of the following cases may occur when the system is rebooting: 
z 
The main boot file is correct and the system boots with the main boot file. 
z 
An error occurs to the main boot file, so the system boots with the backup boot file. 
z 
An error occurs to both the main and backup files, so the system randomly chooses an application 
file for booting. 
z 
If the system fails to boot with the randomly-chosen application file, it supposes that the file system 
is unavailable or no correct boot file is available and thus stops choosing a boot file. 
 
  
z 
If you do not specify the backup boot file but the main boot file only, the system boots with the main 
boot file. If the main boot file has an error, the system randomly chooses an application file for 
booting.  
z 
If you do not specify the main boot file but the backup boot file only, the system boots with the 
backup boot file. 
z 
If you specify neither the main boot file nor the backup boot file, the system randomly chooses an 
application file for booting.
