This option lets you control whether the Trusted Platform Module (TPM) in the system is
enabled and visible to the operating system. When disabled the BIOS will not turn On the TPM
During POST. The TPM will be non-functional and invisible to the operating system. When
enabled, the BIOS will turn On the TPM during POST so that it can be used by the operating
system. This option is Enable by default.
NOTE: 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
this option, the TPM will function exactly as it did before it was disabled.
NOTE: Changes to this option take effect immediately.
