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"
Where C:\AddAHCI\HP-AHCI.xml contains:
<?xml version="1.0" ?>
<unattend xmlns="urn:schemas-microsoft-com:asm.v3"
xmlns:wcm="http://
schemas.microsoft.com/WMIConfig/2002/State">
<settings pass="offlineServicing">

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.
