How to switch to AHCI mode on an image after windows installation

Posted on 2009-02-14

I recently sealed an image on a HP Compaq DC7800 under AHCI mode with a Seagate SATA Drive
I then sent the image to a HP Compaq DC7900 under AHCI mode with a Western Digital SATA Drive.

On the 7900 AHCI was set prior to sending the image.  On boot afterwords it continues to say windows didn't start correctly and it gives me the selection of Save Mode and all the other options.  If I switched afterwords to IDE mode on the 7900 that already had the image sent to it the results were the same.

I then changed to IDE mode on the 7900, then sent the image, and it booted into sysprep and then into windows.
After that I try and change the mode back to AHCI and it would go back into the safemode prompt.

I reinstalled the chipset (No change)
I downloaded the Intel matrix storage manager (English: iata87enu.exe) though when I attempted to install it it states

This computer does not meet the minimum requirements for installing the software.
Setup will exit.

Intel's F6 Instructions I followed with a CD with the following at the root
    iaStor.sys, and
The CD would not boot when using F6

I have not used a Floppy drive yet to perform the same

I have done this in the past with the above files.
I cannot recall the process involved though it was under windows without utilizing a boot disk.

I have to make the image work under AHCI mode and then seal the image afterwords because all the machines that are coming in are already set at that mode and it's too many machines to change it.

Any help is greatly appreciated

    Instructions are here:

    Addendum: If you don't already have iastor.sys on drive, the easiest way to obtain a copy is from the Intel F6 driver rather than trying to extract from Matrix Manager.

    I believe this is the same guide that I was speaking of which worked great.
    After I test I apply it to the image, change to AHCI mode, seal and send back to another 7900 I'll award you the credit.

    I tried both .reg's on the first page though it's not working.
    I add the iastore.sys to windows\system32\drivers
    Then I add the reg file.
    Reboot and directly switch to AHCI mode prior to windows load
    Reboot and let windows launch.
    Same thing at this point, just reboots.

    Any ideas?
