Installing AHCI support for my Windows XP (in dual boot)

[Holey]

Hey fellas!

I am trying to switch my XP installation over from using IDE to ACHI so that I don't have to change the SATA emulation mode in the BIOS every time I want to switch OS's.

Making the registry change is easy - http://support.microsoft.com/kb/922976

The issue is those registry keys do not exist, and I cannot get the AHCI driver to install. I'm assuming that part of the installation of the AHCI driver is the creation of those keys.

My motherboard is an Asus P8Z68-V Pro. I have downloaded the SATA driver from the support page (its the Intel Storage Matrix or something along those lines) which is the thing that enables my AHCI support, yet whenever I run the installation, it fails with the error 'This computer does not meet the minimum requirements for this..' (paraphrased because I can't remember exactly and I'm not in front of my computer at the moment).

So I suppose my question at the end of the day is - How do I get this AHCI driver to install? and if/when it does, will that create the registry keys that I can then change to allow XP to boot when my SATA emulation mode is set to AHCI in the BIOS?

As a backup if i can't get this working, I'll probably try and slipstream the driver using nLite or something and installing fresh.. Would prefer to avoid that though!

Is this Win XP sp3 ?

However, Windows XP does not come with a generic AHCI driver. That means no out-of-the-box AHCI support.

Yes it is SP3 :)

And I use XP purely to run COD4 because Punkbuster won't update to work with Windows 8 -.-

I'm aware there is no generic driver, which is why I've said I've downloaded the AHCI driver for my motherboard, but it is failing to install..

On my AMD board, it was ridiculously easy.

For Intel, I had to go into Device Manager, right click the IDE Adapter/SATA Host Controller and click update driver. From there it installed, and then all I had to do was reboot and change to AHCI in BIOS.

why not move to win 7 bc the cut off date is next year for xp.
