Setting a password
Passwords protect your computer from unauthorized access. When set,
no one can access the computer without entering the correct
password.
There are three types of passwords you can set:
1 Supervisor Password secures your computer against unauthorized
entry to and use of the BIOS Utility.
2 User Password secures your computer against unauthorized use.
3 Hard Disk Password protects your data by preventing
unauthorized access to your hard disk.
Important! Do not forget your Setup and Hard Disk passwords! If
you forget your passwords, please get in touch with your dealer
or an authorized service center.
You can set the passwords using the BIOS Utility.
