NOTE: To view this option, enable Advanced Setup mode as described in
View Advanced Setup options.
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 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 system'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.
NOTE: To view this option, enable Advanced Setup mode as described in
View Advanced Setup options.
Physical Presence Interface (PPI) Bypass
for Clear Commands
The PPI Bypass for Clear Commands option allows the operating system to
manage certain aspects of PTT. When enabled, you are not prompted to confirm
changes to the PTT configuration.
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 Enables or disables the detection of chassis intrusion events. This feature notifies
the user when the base cover has been removed from the computer.
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 Disabled, no notification is displayed and no 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.
By default, the Chassis Intrusion Detection option is disabled.
For additional security, Dell Technologies recommends keeping the Chassis
Intrusion option enabled.
NOTE: To view this option, enable Advanced Setup mode as described in
View Advanced Setup options.
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 erases 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
