When a Power-On Password is set, you are prompted to type a valid password each time the computer is
turned on. The computer cannot be used until the valid password is typed in.

Setting an Administrator Password deters unauthorized users from changing conguration settings. If you
are responsible for maintaining the conguration settings of several computers, you might want to set an
Administrator Password.

access the Setup Utility program. The Setup Utility program cannot be accessed until a valid password
is typed in.
If both the Power-On Password and Administrator Password are set, you can type either password. However,
you must use your Administrator Password to change any conguration settings.
