Besides two default USB 2.0
ports on the I/O panel, there
is one USB 2.0 header on
this motherboard. Each USB
2.0 header can support two
USB 2.0 ports.
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 se-
curity, protects digital identi-
ties, and ensures platform
integrity.
This header accommodates
several system front panel
functions.
