Enhancing existing Vista or Windows 7 images from IDE mode or native AHCI mode
Vista and Windows 7 have a native AHCI driver. If Vista or Windows 7 was installed while in IDE mode, a registry change will allow users to gracefully switch to AHCI mode using the Microsoft driver. See the Microsoft Knowledge Base Article at
Corporate IT may be able to update an existing Vista or Window 7 image that was created in IDE mode to use the Intel AHCI driver. The process requires inserting the Intel AHCI drivers into the image in a
Required software to insert the Intel AHCI driver:
•Windows Preinstallation Environment (WinPE) CD
•Windows OPK (OEM Preinstallation Kit) CD
•PKGMGR.EXE (Package Manager)
The OPK CD is not available for general download. It must be obtained through a Microsoft authorized distributor. PKGMGR.EXE is a tool that installs, uninstalls, configures, and updates features and packages for Vista and Windows 7.
For more information and instructions on OPK or PKGMGR.EXE, go to http://www.hp.com.
The process is as follows:
1.Boot into WinPE.
2.Run PKGMGR.EXE from OPK A sample command line is:
pkgmgr.exe /o:"C:\;C:\Windows" /n:"C:\AddAHCI\HP-AHCI.xml"

3.Reboot the computer.
4.Enter F10 Setup and change SATA Emulation mode to AHCI.
5.Reboot the computer into the OS.
An existing Vista or Windows 7 image using the native AHCI driver can be updated to use the Intel AHCI driver (iastor.sys). The driver can be downloaded from www.hp.com.
NOTE: Be careful when moving an image to computer with a different chipset. The Device ID of the AHCI controller must match what is in the INF or the AHCI driver will fail and the computer will not boot.
