TPM Header/Port 80 Connector (TPM Port)
The TPM header is used to connect a Trusted Platform Module (TPM), which is available from
a third-party vendor. A TPM is a security device that supports encryption and authentication
in hard drives. It enables the motherboard to deny access if the TPM associated with the
hard drive is not installed in the system.
