Administrator password
When a Administrator
Password is set, it deters unauthorized persons
from changing configuration settings. If you are responsible for
maintaining the settings of several computers, you might want to set a
administrator Password.
After you set a
Administrator Password, a password prompt is displayed
each time you try to access the Setup Utility program.
If both the
Administrator
and
Power-On are set, you can type either
password. However, to change any configuration settings, you must use
your
administrator password.
