AHCI implememtation under VISTA

I implemented AHCI on a Vista Ultimate system with three SATA drives
(changed the registry to load the MSAHCI service). I think I ended up with
two arrays - one containing all the partitions on the boot drive and a
second array for the other two drives. I used Vista to recreate the
partitions on the second array and everything seemed to function normally -
except the Intel Matrix Storage Console 8.5 said that NCQ was not
implemented on the non-boot drives. I can go back and forth between IDE and
AHCI and Vista does not have a problem with the partitions on the boot drive
but the other two drives are a problem. I have given up on AHCI unless
someone can point me to some good technical information on how it works. I
have another system with the almost exact same configuration running Raid0
and wth two arrays it works just fine with NCQ turned on for both arrays. I
know, stick with IDE or Raid but AHCI has become a personal thing!! Also, I
was hoping I could find a way to go to a true Raid0 configuration on the
AHCI system without having to reinstall Vista. Help would be welcome.
