This motherboard supports
CASE OPEN detection feature
that detects if the chassis cove
has been removed. This feature
requires a chassis with chassis
intrusion detection design.
This connector supports Trusted
Platform Module (TPM) system,
which can securely store keys,
digital certificates, passwords,
and data. A TPM system also
helps enhance network security,
protects digital identities, and
ensures platform integrity.

add-in card (AIC) to this
connector via the GPIO cable.
