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, you must supply the recovery key
when you restart your system or program before you can access the encrypted data on your hard
drives.
CAUTION: Do not attempt to remove the TPM plug-in module from the motherboard. Once the
TPM plug-in module is installed, it is cryptographically bound to that specific motherboard. Any
attempt to remove an installed TPM plug-in module breaks the cryptographic binding, and it
cannot be re-installed or installed on another motherboard.
