System Security Screen

Option	Description
TPM Security	Sets the reporting of the Trusted Platform Module
(Off default)	(TPM) in the system.
	If Off, the presence of the TPM is not reported to the
	operating system.
	If On with Pre-boot Measurements, the system reports
	the TPM to the operating system and stores the pre-boot
	measurements to the TPM during POST.
	If On without Pre-boot Measurements, the system
	reports the TPM to the operating system and bypasses
	pre-boot measurements.
TPM Activation	When set to Activate, the TPM is enabled to default
	settings. When set to Deactivate, the TPM is disabled.
	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	CAUTION: Clearing the TPM will lose all encryption
	keys in the TPM. This option prevents booting to the
	operating system and results in data loss if the
	encryption keys cannot be restored. Back up the TPM
	keys prior to enabling this option.
	When set to Yes, all TPM contents are cleared.
	NOTE: This field is read-only when TPM Security is set
	to Off.
Intel (R) TXT	Enables/disables Trusted Execution Technology. To
(Disabled default)	enable TXT, enable & activate VT & TPM with preboot
	measurement.
System Password	Displays the current status of the password security
(Not Enabled default)	feature and allows a new system password assignment and
	verification.
	NOTE: See "Using the System Password" on page 49 for
	more information.
