System Password Displays the current status of your system's password security feature and allows
you to assign and verify a new system password.
NOTE: See "Using the System Password" on page 38 for instructions on assigning a
system password and using or changing an existing system password.
Setup Password Restricts access to the System Setup program in the same way that you restrict
access to your system using the system password feature.
NOTE: See "Using the Setup Password" on page 40 for instructions on assigning a
setup password and using or changing an existing setup password.
Password Status Setting the Setup Password option to Enabled prevents the system password from
being changed or disabled at system start-up.
To lock the system password, assign a setup password in the Setup Password option
and then change the Password Status option to Locked. In this state, you cannot
change the system password using the System Password option and cannot be
disabled at system start-up by pressing <Ctrl><Enter>.
To unlock the system password, enter the setup password in the Setup Password
field and then change the Password Status option to Unlocked. In this state, you
can disable the system password at system start-up by pressing <Ctrl><Enter>
and then change the password using the System Password option.

off immediately after the power button is pressed.
The button is enabled in the System Setup program. When disabled, the button

NOTE: You can still turn on the system by using the power button, even if the Power
Button option is set to Disabled.

personnel or by the operating system's documentation. Pressing this button
