is there any difference, other than digital signature, between driver in windows and the other one from intel?
when xp finds new hardware I can choose one of these:

After a month and a half using AHCI, I went back to IDE.
Some of you might be interested in the reasons:
1. Burst rate is significantly worse with AHCI.
HDTune reports 120MB/s with AHCI versus 140MB/s with IDE
HD Tach reports 200MB/s with AHCI versus 225MB/s with IDE.
(why Tune & Tach don't give the same values is a mystery, but in all cases IDE > AHCI)
2. CPU consumption is definitely higher when using AHCI compared to IDE for seemingly no speed increase whatsoever.
3. AHCI introduces a HDD sleep bug !
I have 2 HDDs. In XP (SP3) power management, I set to switch off the HDDs after 2 hours of inactivity.
When I'm using AHCI, the 2nd HDD never goes to sleep, EVER, if the first one isn't already asleep.
With the same power management settings under IDE, no problem, 2nd HDD goes to sleep after desired time alright even if first HDD keeps being active.
4. Resume from standby is a bit slower.
So for now i'll forget about AHCI for my current config.
Btw, going back to IDE is easy as hell, just swith back to IDE in BIOS, reboot and all is fine.
If you're sure you won't be ever going back to AHCI you can remove the intel matrix storage manager driver (iaStor)

Looks like there is a typo in the Registry File:

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2923&cc_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

Should be:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2923&cc_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

Good one, I didn´t think about that and I will edit it directly, credits to you, thank you.

I've had the same experiences with vista as well as xp 64. However, once i installed proper drivers, the hdd sleep bug went away. I think its more work to have it installed as starting other things from cd/dvd that does have its own ahci drivers on media will not recognize drives. Its more hazzle then its worth for performance, and there is very neglible gain at _best_.

Hi Everyone!

I have a Gigabyte P35-DS3 Rev1.0 (ICH9) motherboard with a SATAII HDD and I use Vista 32-bit. But I CANNOT activate the AHCI features, such as NCQ.
I know that Vista supports AHCI out of the box.
When I tried to install Vista in AHCI mode:
- Vista saw my HDD and started install itself
- after about 5 minutes the intallation stopped (no BSOD, no error message, just stopped)
So I could install it in IDE-emulate mode. After the installation I switched to AHCI and then BSOD under startup.
So I did these instructions: http://support.microsoft.com/kb/922976
Now I can use Vista in AHCI mode but I DON'T use the AHCI features (NCQ, hot-plugging) and the speed is a bit slower than before...

Can someone give me any suggestion?

Thx in advance!

[Rackman]

It works very well on a Gigabyte GA-P35-S3G !
Thank you.

Interesting... Has anyone ever tried implanting Msahci.sys onto XP? I would take a look at it, but don't have enough knowledge... (and Vista, too).

This is interesting. I thought running the drive in native mode would benefit at least a LITTLE bit...

I am currently running the modified driver.
For the last two days, I have been fooling with making bootable cd's and bootable USB. These devices do not have the drivers for the harddrive in ahci so they either crash or just do not see the hard drive. (I had enough trouble just getting the usb image to work at all, so I have not tried to add in the hacked driver).

So I decided to revert back to IDE mode, but when I set the bios back, all I got was the BSOD/stop screen, at about the point where it should be loading the desktop. (this is booting from the normally working harddrive not usb or cd) I didnt try anything else yet, like removing the HD or controller devices from the device manager, or seeing if i can roll back a driver. I dont want to get myself into a situation that I cannot boot the drive at all. I set it back to ahci and it boots fine, but for now I am stuck in ahci.

I thought I did get it to revert back on the first day, but it is not working for me now.
So for me at least, going back was not 'easy as hell'. GA-P35-S3G. maybe I will try it another day.

Just a quick heads up... Intel released new drivers yesterday and it seems as if they have changed some things inside the .inf files. Has anyone had a chance to look into this? I'd really like to try this out, but I'd also prefer to use the latest drivers if possible.

I will install system onto other HDD with these in few mins. What exactly do you want to know?

Well, I can tell you that the steps listed in the first post are no longer valid for the latest drivers. I'm sure I could figure out how to achieve the same results based on the previous instructions, but I was just wondering if anyone was already working on that. I'm sort of hoping that Intel changes their minds and incorporates AHCI support into their driver, but I can tell you I tried to slipstream these into my last Windows install and it didnt work.

Just to note:
The line that was originally supposed to be replaced in the .inf file is no longer present.

[Octopuss]

Hm, well, I just installed the system with help of a diskette with the driver so I can't really comment on this. Didn't work otherwise.
But once installed, it works perfectly. I even have an impression it's a bit faster.

Perhaps I should clarify...
I'm running a Gigabyte GA-EP35-DS3L (with ICH9)
I would like to enable AHCI in Windows XP
The initial post by puntomx described how to do that on a current installation after some minor modifications.
On page 3 of this topic, a method for doing this on a fresh install is also listed by Vascoman
Both methods are basically the same, with the only real exception being a registry edit

What I'm saying is that the instructions listed in both of those posts are no longer valid for the latest chipset drivers, posted on June 2nd, because the line that needs to be replaced is not present. I was just wondering if the original poster or anyone else has had a chance to look into this yet. I have not tried anything yet myself, other than seeing if Intel had incorporated support for AHCI on ICH9 in those drivers. Unless I messed up when I slipstreamed the drivers into my Windows install cd, the answer is no.

Oh, shame on me, not installation, but messing about with already installed system. Nevermind then

I would like to look into it but I have my system now up and running with Vista. If you have time and you like to contribute I would be very pleased with it. Sure you will get the credits .

Hi puntoMX
We had some private testers going at the "beta", and now that the official AHCI is released by intel, we put up a driverpack for mass storage including that new driver.

I will eventually be able to personally test all BIOS settings in a ICH7, an ICH9 and an ICH9R.
XP live tests take time, and I wish I had 46 hours in a day.

What I am saying is that driverpack.net have a testpack with the latest, ready for integration, and we are interested about comparatives and (also) on how it does without us hacking into files. (you know that when it works well without a hack, you don't want to break it.)

I promised we would not forget you people, and I hope intel made the right choice for you.
You see, IF it can be done by F6, it can be done by driverpacks.
(I will also soon look at adding USB drives to driverpacks, so that ...)

EDIT.. my personal tests so far were on a hi end gigabyte mobo, ICH9R, in a raid5 array. (blot in that HW is a Jmicron duplicate for tertiary controller. mobo has 8 sata rails.).
other testplank is an abit with ICH9 (which does not offer AHCI in BIOS mobo has six sata rails.)

I am saying I've got some freaks to test. (I have stored 7 issue rich testplanks).
Some of these boards should not have been sold to public. I kept these as litmus test.

Hi

Just updated to the new 8.2.0.1001 drivers. I was previously using 7.8 installed with the instructions provided here. All I did to update was change the inf file on the new drivers, and update using device manager. Everything good so far.

Using Gigabyte GA-P35-S3L with bios F6 and Win XP Pro SP2

Thanks

Can I second the request for post 1 and the page 3 alternative to be updated. I downloaded latest and got confused as hell. BTW, its Ctrl-H not Ctrl-R for Search/Replace... that got me confused before I even found out that there is no 2923 to search for in first place!!!
