TPM Header/Port 80
This 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. See the table on the right
for pin defi nitions.
