Description
Restricts access to the System Setup program by using a
setup password.
NOTE:

more information.
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" on page 76 for more
information.
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.
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.
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.
