Password Status
(Unlocked default)
When Setup Password is assigned and this field is 
Locked, the system password cannot be changed or 
disabled at system start-up.
See "Using the System Password" for more information.
TPM Security
(Off default)
Sets the reporting of the Trusted Platform Module 
(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
(No Change default)
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.
