The built in win 7 AHCi drivers simply mean you don't have to install any drivers during the windows install (i.e the equivelent of F6 driver install with win XP). Once windows is on it is better to use the intel matrix driver for ahci rather then the windows one.
Windows 7 will most likely detect all your hardware with the built in drivers. Installing the ones i have mentioned will give you the best performance/stability. And yeah the intel drivers are for pretty much all the intel chipsets regardless of manufactuer they aren;t tied to a specific board.
