CAUTION: If you are using the Trusted Platform Module (TPM) with an encryption key, you may
be prompted to create a recovery key during program or System Setup. Be sure to create and
safely store this recovery key. If you replace this system board, supply the recovery key when you
restart your system or program before you can access the encrypted data on your hard drives.

TPM plug-in module is installed, it is cryptographically bound to that specific system board. Any
attempt to remove an installed TPM plug-in module breaks the cryptographic binding, and it
cannot be re-installed or installed on another system board.
