WORD"  

 

1. When "Setup" is selected in the Security Option: 

When you use the "User Password" to log into the BIOS setup program, you 

can only view the BIOS settings, but you cannot change any settings. The only 

setting you can change is the "User Password" and you can also select "SAVE 

& EXIT SETUP" and "EXIT WITHOUT SAVING" from the main menu. (If you use 

the Supervisor Password to log into the PC system, you will have the complete 

rights to all the BIOS settings. 

 

2. When "System" is selected in Security Option: 

When you turn on the PC system, it will request that you enter the Password. 

Without the correct password, the PC system will stop and the operating sys-

tem won't be loaded. 

 

B. When there is no password stored in the "SUPERVISOR PASS-

WORD" 

 

1. When "Setup" is selected in Security Option: 

Users can use the "User Password" to log into the BIOS setup program, and 

they can change any of the BIOS settings.  

 

2. When "System" is selected in Security Option: 

When you turn on your PC, you will be requested to enter the Password. With-

out the correct password, the PC system will stop and the operation system 

will not be loaded.
