Option	Description
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.
Power Button	Turns system's power off and on.
	• If you turn off the system using the power button and the system is running an ACPI-
	compliant operating system, the system can perform an orderly shutdown before
	power is turned off.
	• If the system is not running an ACPI-compliant operating system, power is turned off
	immediately after the power button is pressed.
	The button is enabled in the System Setup program. When disabled, the button can
	only turn on system power.
	NOTE: You can still turn on the system by using the power button, even if the Power
	Button option is set to Disabled.
NMI Button	NOTICE: Use the NMI button only if directed to do so by qualified support
	personnel or by the operating system's documentation. Pressing this button halts
	the operating system and displays a diagnostic screen.
	Enables or disables the NMI feature.
