Installing the Motherboard
SATA1~4: Serial ATA connectors
These connectors are used to support the new Serial ATA devices for the highest data
transfer rates (3.0 Gb/s), simpler disk drive cabling and easier PC assembly. It elimi-
nates limitations of the current Parallel ATA interface. But maintains register com-
patibility and software compatibility with Parallel ATA.
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 indi-
cated above. A different pin assignment may cause damage or system hang-
up.
