description
Allows you to enable/disable solenoid hood cover lock.
NOTE: Notify User alerts the user that the sensor has detected that the
cover has been removed. Setup Password requires that the setup
password be entered to boot the workstation if the sensor detects that
the cover has been removed.
This feature is supported on select models only.
Allows you to assign or modify a master or user password for
certain hard drives. When 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 drive that supports
the DriveLock feature is attached to the system.
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 workstation 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.
NOTE: 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.
Saves a backup copy of the Master Boot Record of the current
bootable disk.
NOTE: Only appears if MBR Security is enabled.
