Table 1-7. New System Security Screen Options Option TPM Security (Off default) TPM Activation TPM Clear (No default) Description 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. 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. 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. 22 Information Update
