Installing the Motherboard
USB2~3: Front Panel USB headers
The motherboard has four USB ports installed on the rear edge I/O port array.
Additionally, some computer cases have USB ports at the front of the case. If you
have this kind of case, use auxiliary USB connector to connect the front-mounted
ports to the motherboard.
Please make sure that the USB cable has the same pin assignment as
indicated above. A different pin assignment may cause damage or system
hang-up.
Trusted Platform Module (TPM) is a published specification detailing a
microcontroller that can store secured information, and implementations of that
specification.
