This COM1 header
supports a serial port
module.
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.
This is an interface
for print port cable
that allows convenient
