Re: AHCI Implementation

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.


This may depend on the particular MB BIOS. On my Asus P5B Dlx there
are three settings for SATA drives, the default use as IDE, AHCI for
single drives or drives not in a RAID setting, and RAID for setting up
RAID 0,1,5,or 10, or using the Intel Matrix Storage Tecchnology option
ROM to set up advanced RAID.
