Re: AHCI Implementation

The following is one of the links that I came up with using suggested search
criterions for my upgraded XP system a few months ago and I did see a few
for Vista but since I don't use Vista anymore, so I didn't keep it.

Sorry it didn't help you.

I must be real stupid because all I ever come up in my searches is a bunch
of people discussing their various BIOSRegistry 101 problems with AHCI and
a few other sites telling me how great it is. Let me ask the question
another way - Does anybody out there actually use VISTA with the BIOS set
for AHCI mode with multiple SATA drives? If so, please discuss with me.

My main question was/is does anybody out there know how AHCI works under
VISTA or at least point me to some technical information on what the
heck it is really doing/trying to do in a multi disk situation.

You can search the net using key words including chipset name (or
controller name) + Vista + AHCI or any combination of those keywords and
you will get plenty of information.

Hope this give you some directions.

Yes, I have all the same stuff on my P5B Deluxe MB and my two abit IP35
Pro motherboards. I have used the IDE and Raid settings with no
problems or issues. My main question was/is does anybody out there know
how AHCI works under VISTA or at least point me to some technical
information on what the heck it is really doing/trying to do in a multi
disk situation.

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.
