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. SATA1~6: Serial ATA connectors
SATA3~6 connectors are used to support the Serial ATA 3.0Gb/s device, SATA1/2 con-
nectors support 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 main-
tains register compatibility and software compatibility with Parallel ATA.
The black SATA6 connector will become unavailable when miniPCI-Ex1 slot/ mSATA connector
is installed.
