Information Update
Table 1-7. New System Security Screen Options
Option Description
TPM Security
(Off default) Sets the reporting of the Trusted Platform Module
(TPM) in the system.
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.
TPM Clear
(No default)
CAUTION:
Clearing the TPM causes loss of all
encryption keys in the TPM. This prevents booting to
the operating system and results in loss of data if the
encryption keys cannot be restored. Be sure to back up
the TPM keys prior to enabling this option.
When set to Yes, all the contents of the TPM are cleared.
NOTE:
This field is read-only when TPM Security is set
to Off.
