TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM)/Port 80, which
is available from Supermicro. 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 storage drive is not installed in the system. For more information
on the TPM: http://www.supermicro.com/manuals/other/TPM.pdf.
