BIOS ROM
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.
See the Desktop Management Guide on the Documentation CD for
more information.

Security

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 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
Record*
Saves a backup copy of the Master Boot Record of the current
bootable disk.
✎
Only appears if MBR Security is enabled.
