Enable or disable the function that protects
items in ThinkPad Setup from being
changed by a user who does not have the
supervisor password. By default, this is
set to Disabled. If you set the supervisor
password and enable this function, no one
but you can change any items in ThinkPad
Setup.
If you select and enable Password at
unattended boot, a password prompt is
displayed when the computer is turned on,
from either a power-off state or hibernation
state, by an unattended event such as Wake
on LAN. If you select Disabled, no password
prompt is displayed; the computer goes
ahead and loads the operating system. To
prevent unauthorized access, set the user
authentication on the operating system.
Specify a minimum length for power-on
passwords and hard disk passwords. If you
set the supervisor password and specify a
minimum length for passwords, no one but
you can change the length.
See "Power-on password" on page 50.
See "Hard disk passwords" on page 50.
Note: Hard Disk 1 means that the hard disk
drive is built into your computer.
