			Setup Utilities and Diagnostic Features
Heading	Option		Description (Continued)
Security	DriveLock*	Allows you to assign or modify a master or user password for
(continued)		certain hard drives. When enabled, the user is prompted to
		provide one of the DriveLock passwords during POST. If neither
		is successfully entered, the hard drive will remain inaccessible
		until one of the passwords is successfully provided during a
		subsequent cold-boot sequence.
		This selection will only appear when at least one drive that
		supports the DriveLock feature is attached to the system.
	Master Boot	Allows you to enable or disable Master Boot Record (MBR)
	Record Security*	Security. When enabled, the BIOS rejects all requests to write to
		the MBR on the current bootable disk. Each time the computer is
		powered on or rebooted, the BIOS compares the MBR of the
		bootable disk to the previously saved MBR. If changes are
		detected, you are given the option of saving the MBR on the
		current bootable disk, restoring the previously saved MBR, or
		disabling MBR security, You must know the password if one is
		set.
		✎	Disable MBR Security before intentionally changing the
			formatting or partitioning of the current bootable disk.
			Several disk utilities (such as FDISK and FORMAT) attempt to
			update the MBR. If MBR Security is enabled and disk
			accesses are being serviced by the BIOS, write requests to
			the MBR are rejected, causing the utilities to report errors. If
			MBR Security is enabled and disk accesses are being
			serviced by the operating system, any MBR change will be
			detected by the BIOS during the next reboot, and an MBR
			Security warning message will be displayed.
	Save Master	Saves a backup copy of the Master Boot Record of the current
	Boot Record*	bootable disk.
		✎ Only appears if MBR Security is enabled.
	Restore Master	Restores the backup Master Boot Record to the current bootable
	Boot	disk.
	Record*	✎ Only appears if all of the following conditions are true:
			MBR Security is enabled.
			A backup copy of the MBR has been previously saved.
			The current bootable disk is the same disk from which the
			backup copy of the MBR was saved.
	Device Security	Enables/disables serial ports A & B; parallel and USB ports;
		system audio; network controller (some models); and SCSI
		controllers.
	Network Service	Enables/disables Network Service Boot. (Feature supported on
	Boot	select models only.)
