B75H2-M3 USER MANUAL

Trusted platform module (TPM) is a published specification detailing a micro con-
troller that can store secured information, and implementations of that specifica-
tion.

7. TPM: Trusted Platform Module header

The motherboard has two USB 2.0 headers supporting four USB 2.0 ports. Addition-
ally, 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.

6. F_USB1~2: Front Panel USB 2.0 headers

Please make sure that the USB cable has the same pin assignment as indi-
cated above. A different pin assignment may cause damage or system hang-
up.
