Using the System Setup Program
TPM Security
(Off default) Sets the reporting of the Trusted Platform Module
(TPM) in the system.
NOTE:
The TPM is a microchip that is integrated into the
system board, and it can be used by both operating systems
and programs. It is capable of creating, storing, and
protecting cryptographic keys. See support.dell.com for
additional TPM documentation.
When set to Off (default), presence of the TPM is not
reported to the operating system.
When set to On with Pre-boot Measurements, the
system reports the TPM to the operating system and
stores the pre-boot measurements (compliant with
Trusted Computing Group standards) to the TPM during
POST.
When set to On without Pre-boot Measurements, the
system reports the TPM to the operating system and
bypasses pre-boot measurements.
TPM Activation Changes the operational state of the TPM.
When set to Activate, the TPM is enabled and activated
at default settings.
When set to Deactivate, the TPM is disabled and
deactivated.
The No Change state initiates no action. The operational
state of the TPM remains unchanged (all user settings for
the TPM are preserved).
NOTE:
This field is read-only when TPM Security is set to
Off.
