TPM Header
The Trusted Platform Module (TPM)/Port 80 is located at JTPM1 and is available from
SMCI (optional). A TPM/Port 80 connector is a security device that supports encryption and
authentication in hard drives. It allows the motherboard to deny access if the TPM associated
with the hard drive is not installed in the system. See the table below for pin definitions.
