Option Description
data loss, HP recommends this setting only in situations where security integrity of the system is
a higher priority than the risk of potential data loss.
Smart Cover
● Cover Removal Sensor (Disabled/Notify user/Administrator password)
Lets you disable the cover sensor or configure what action is taken if the computer cover is removed. Default
is Disabled.
NOTE: Notify user alerts the user with a POST error on the first boot after the sensor detects removal of
the cover. If the password is set, Administrator Password requires that the password be entered to boot the
computer if the sensor detects that the cover has been removed.
Intel Software Guard Extensions (SGX)
Intel SGX is a set of processor code instructions from that allows user-level code to allocate private regions
of memory, that unlike normal process memory is also protected from processes running at higher privilege
levels.

● Save/Restore MBR of System Hard Drive
NOTE: Windows 10 systems are generally not formatted to include an Master Boot Record
(MBR). Instead they use GUID Partition Table (GPT) format, which better supports large hard drives.
Enabling this feature will save the MBR of the system hard drive. If the MBR gets changed, the user will
be prompted to restore the MBR. Default is disabled.
The MBR contains information needed to successfully boot from a disk and to access the data stored
on the disk. Master Boot Record Security can prevent unintentional or malicious changes to the MBR,
such as those caused by some viruses or by the incorrect use of certain disk utilities. It also allows you
to recover the "last known good" MBR, should changes to the MBR be detected when the system is
restarted.
NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS
cannot prevent changes that may occur while the operating system is running.
Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
Only appears if all of the following conditions are true:
–
MBR security is enabled.
– A backup copy of the MBR has been previously saved.
– The current bootable disk is the same disk from which the backup copy was saved.
