I'd say RTFM (read the frickin' manual), but I see that the Gigabyte manual is pretty weak on SATA drivers.
What mode is the board's SATA controller set to? If it's native IDE, I doubt that you'd need any additional drivers. Win7 includes AHCI drivers that will support some motherboards, but I wouldn't be surprised if newer AMD chipsets are not supported. I didn't need to do this on my desktop system (Intel X58 chipset); I forget whether it was required on my notebook (nVidia chipset), although it probably was.
At the risk of stating the obvious: the AHCI and RAID drivers for download from the link that you posted are self-extracting archives. You need to run the .exes to expand the archives into the directory of your choice. (They default to the directory where you run the .exe. Fortunately, they extract into folders.) The files are what you need to copy onto the USB key drive for use during the Win7 installation.
Please stop posting like a fifteen year old, even if you happen to be one. You'd probably get more, or better, help.
