This option lets you control whether the Trusted Platform Module (TPM) in the system is enabled and visible to the operating system.
When disabled (check box is empty), the BIOS will not turn on the TPM during POST. The TPM will be non-functional and invisible to the
operating system. When enabled (check box filled) the BIOS will turn the TPM on during POST so the it can be used by the operating
system.
Disabling this option does not change any settings you may have made to the TPM, nor does it delete or change any information or keys
you may have stored there. It simply turns off the TPM so that it cannot be used. When you re-enable the TPM, it will function exactly as
it did before it was disabled.
TPM Security
Once TPM is enabled (check box filled), the available settings are Deactivate, Activate, and Clear.
With the TPM in Deactivate mode, it will not execute any commands that use the resources of the TPM, nor will it allow any access to
stored owner information.
The Clear setting allows the owner's information stored in the TPM to be cleared. Use this to restore the TPM to its default state if you
lose or forget the owner authentication data.
