password
To control access to setting or changing the system configuration, set an
administrator password and enable it through Setup or the SSU.
If both the administrator and user passwords are enabled, either can be used to
boot the system or enable the keyboard and/or mouse, but only the
administrator password allows changes to Setup and the SSU.
Once set, passwords can be disabled by setting the password to a null string or
by changing the Clear Password jumper. See Chapter 3 for more information.

fully but requires a password before accepting any keyboard or mouse input.
