Desktop Management
DriveLock
Allows you to assign or modify a master or user password for
MultiBay hard drives (not supported on SCSI 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.
See the
Desktop Management Guide
on the
Documentation
CD
for more information.
Master Boot 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
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.
