Put all driver folders into one folder and instruct nLite with the second option, to get multiple drivers. It will take all the .inf files, but only install the one needed for your PC. As to the SATA/AHCI drivers, you have to install them in TXT mode (not PnP), and I think (maybe someone can confirm it) that if you choose IASTOR.inf, it will also copy IAHCI.inf, and the other way around. Also, make sure to integrate SATA/AHCI drivers last in the process.
