Table 2-8. System Security Screen Options (continued) Option TPM Security (Off default) TPM Activation Description 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. 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. 54 Using the System Setup Program
