CAUTION: If you are using the Trusted Program 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.

CAUTION: To prevent damage to the processor pins when replacing a faulty system
