1. USB3F: Front Panel USB 3.0 header
This Motherboard implements one USB 3.0 header supporting 2 extra front USB 3.0
ports, which delivers 5Gb/s transfer rate.
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.
2. SATA1~4: Serial ATA connectors
SATA2~4 connectors are used to support the Serial ATA 3.0Gb/s devices, and SATA1
connector supports the Serial ATA 6.0Gb/s device, 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.
