Installing the Motherboard
USB3/USB4: 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 connectors 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.
SPDIFO1: SPDIF out header
This is an optional header that provides an S/PDIF (Sony/Philips Digital Interface) output
to digital multimedia device through optical fiber or coaxial connector.
SATA1/SATA2: Serial ATA connectors
These connectors are use to support the new Serial ATA devices for the highest date transfer
rates (150 MB/s), simpler disk drive cabling and easier PC assembly. It eliminates limitations
of the current Parallel ATA interface. But maintains register compatibility and software
compatibility with Parallel ATA.
