TPM Header (JTPM1)
This header is used to connect a Trusted
Platform Module (TPM), available from
a third-party vendor. A TPM is a secu-
rity device that allows encryption and
authentication of 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 denitions.
