HELP - Enabling AHCI in Windows 7 on Macbook Pro

[idata]

I've been reading around but haven't figured out a way to enable AHCI in Windows 7 for a Macbook Pro. I do not believe doing that registry hack does anything for me (here is the hack i'm talking about). It seems you have to run some type of script to get it to work, looks complicated!

Vista 32/64 Windows 7 32/64

- Run Regedit- Navigate to "HKLM\System\CurrentControlSet\Services\msahci "- edit the "Start" key and change the value from what it is to "0"- this will tell Vista to check for AHCI on next boot and install the AHCI driver if it is in AHCI mode- this installs the generic AHCI Microsoft driver and it is really a poor driver for your hardware and you will need the Intel ones to get full performance.

The only sites I've seen that looks remotely close to enabling it is..

Has anyone actually enabled it on a mac laptop or desktop? How do I know if AHCI is enabled or not or actually working? Do I have to run the script every time I use Windows 7?

Setup on Intel X25-M 160gb G2:

Windows 7 x64 Ultimate 40gb

Mac Snow Leopard 120gb

I think that "should" mean you're running AHCI, but I'm not sure how that's possible. People in the apple support forums haven't had any luck enabling AHCI mode in bootcamp.

The only difference in my installation is that I let Windows 7 detect everything which it did except 4 devicies (ACPI\APP0001,ACPI\APP0002, ACPI\APP000B, and USB\VID_05AC&PID_8507&REV_0419&MI_02) I did not use any of Apple supplied drivers. I did not use Nvidia's Chipset Drivers for SATA, but i did use the Nvidia's SMC and SMU drivers provided by Apple bootcamp.
