Three password types protect your computer from unauthorized access. Setting these passwords creates
several different levels of protection for your computer and data:
6
Setup Password prevents unauthorized entry to the BIOS Utility. Once set, you must key-in this
password to gain access to the BIOS Utility.
6
Power-On Password secures your computer against unauthorized use. Combine the use of this
password with password checkpoints on boot-up and resume from hibernation for maximum
security.
6
Hard Disk Password protects your data by preventing unauthorized access to your hard disk.
Even if the hard disk is removed from the computer and moved to another computer, it cannot be
accessed without the Hard Disk Password.
