TPM/Port 80 Header
A Trusted Platform Module (TPM)/Port 80 header is located at JTPM1 to provide TPM support
and a Port 80 connection. TPM is a security device that supports encryption and authentication
for hard drives. It enables the motherboard to deny access if the TPM associated with the
hard drive is not installed in the system.
