Uses this style of SATA data cable, and connector on motherboard,http://en.wikipedia.org/wiki/File:SATA_ports.jpg
(NOTE* Color does NOT matter for cable connector.
Color really doesn't matter, for a SATA connector on the motherboard, either.
You are supposed to plug the Primary SATA harddrive, into the SATA 1 connector, on the motherboard.

BIOS will find the harddrive with the Operating System on it, and will find all the other SATA devices plugged into the motherboard, too )
You do NOT have SATA.
