Heading	Option	Description
Security	Master Boot Record	Allows you to enable or disable Master Boot
(continued)	Security*	Record (MBR) 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
		current 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 setup 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.

Support for Computer Setup options may vary depending on your specific hardware configuration.

*Option not supported on all products.
