Trusted Platform Module Header
The JTPM1 header is used to connect
a Trusted Platform Module (TPM),
available separately from a third-party
vendor. A TPM is a security device that
allows encryption and authentication of
hard drives, disallowing access if the
TPM associated with it is not installed
in the system. See the table on the
right for pin defi nitions.
