• Chassis serial number or Universal Unique Identifier (UUID)

 

 

 

number. The UUID can only be updated if the current

 

 

 

chassis serial number is invalid. (These ID numbers are

 

 

 

normally set in the factory and are used to uniquely identify

 

 

 

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 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.

 

 

 

 

 

 

 

Save Master Boot

Saves a backup copy of the Master Boot Record of the current

 

 

Record*

bootable disk.

✎Only appears if MBR Security is enabled.

*Option supported on select models.
