GIGABYTE - Motherboard - Socket 1155 - GA-P61-S3 (rev. 2.0)

Ive installed the rest of the drivers provided by manufacturer except the SATA RAID/AHCI ones.The Intel Rapid Storage Technology gave me an error that I dont meet the system requirements so I no longer insisted with the others. Hmmm, why are these listed for my motherboard then? or what exactly are they?
I was thinking I need to instal first the "Intel SATA Preinstall driver(For AHCI / RAID Mode) Note: Press F6 during Windows setup to read from floppy" -the last item on the list -but dont know how , there are just some "sytem files, security catalog, setup information". You can fast download and checked them.
