Security
NOTE: When disabled, this feature may cause compatibility issues or loss of
functionality in some operating systems.
Key Storage Enable The Key Storage Enable option controls the storage hierarchy of TPM, which is
used to store digital keys. Disabling the Key Storage Enable option restricts the
ability of TPM to store owner's data.
By default, the Key Storage Enable option is enabled.
For additional security, Dell Technologies recommends keeping the Key Storage
Enable option is enabled.
NOTE: When disabled, this feature may cause compatibility issues or loss of
functionality in some operating systems.
Clear When enabled, the Clear option clears information that is stored in the TPM
after exiting the computer's BIOS. This option returns to the disabled state when
the computer restarts.
By default, the Clear option is disabled.
Dell Technologies recommends enabling the Clear option only when TPM data is
required to be cleared.
Physical Presence Interface (PPI) Bypass
for Clear Commands
By default, the PPI Bypass for Clear Commands option is disabled.
For additional security, Dell Technologies recommends keeping the PPI Bypass
for Clear Commands option disabled.
Chassis intrusion
Chassis Intrusion The chassis intrusion detection enables a physical switch that triggers an event
when the computer cover is opened.
When set to Enabled, a notification is displayed on the next boot and the event
is logged in the BIOS Events log.
When set to On-Silent, the event is logged in the BIOS Events log, but no
notification is displayed.
When set to Disabled, no notification is displayed and no event is logged in the
BIOS Events log.
By default, the Chassis Intrusion option is enabled.
For additional security, Dell Technologies recommends keeping the Chassis
Intrusion Detection option is disabled.
AMD Memory Guard
AMD Memory Guard Enables or disables memory encryption. AMD Memory Guard encrypts the
contents of RAM to provide enhanced protection against unauthorized access.
While enabling this feature may make detecting RAM errors more difficult during
testing, it will not produce false errors. Enabling AMD Memory Guard may have a
small performance impact on memory. This feature is only available on CPUs with
AMD Pro technology.
By default, the AMD Memory Guard option is disabled.
Data Wipe on Next Boot
Start Data Wipe Data Wipe is a secure wipe operation that deletes information from a storage
device.
CAUTION: The secure Data Wipe operation deletes information in a
way that it cannot be reconstructed.
Commands such as delete and format in the operating system may remove files
from showing up in the file system. However, they can be reconstructed through
