DriveLock Security

Allows you to assign or modify a master or user password for

 

 

 

MultiBay hard drives. When this feature is 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 MultiBay drive

 

 

 

that supports the DriveLock feature is attached to the system.

system being used comprehend and utilize the function.

Security

Master Boot

(continued)

Record Security*

Allows you to enable or disable Master Boot 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 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.

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