Enhancing existing Windows XP images from IDE Mode
Corporate IT may be able to update an existing Windows XP image to be AHCI-
compatible that was created in IDE mode. The process requires inserting the AHCI
drivers into the image in a pre-installation environment. Once that is done, the
system can be switched to AHCI mode safely.
Required software to insert the AHCI driver:
• Windows Preinstallation Environment (WinPE) CD
• Windows OPK (OEM Preinstallation Kit) CD
• MSDINST.EXE (Mass Storage Device Installer)
The OPK CD is not available for general download. It must be obtained through a
Microsoft authorized distributor. MSDINST.EXE is a tool designed to insert mass
storage drivers into an offline Microsoft Windows XP image.
For more information and instructions about OPK or MSDINST.EXE go to
http://www.microsoft.com.
The process for updating an existing Windows XP image to be AHCI compatible is
as follows:
1. Boot into WinPE.
2. Run MSDINST.EXE from OPK.
MSDINST.EXE is executed from a command line where the location for the .inf
file containing the PnP ID of the RAID/AHCI SATA controller of the target
system and location of the Windows directory are specified.
For example: Newmsd.inf has the PnP IDs and it is in the C:\AddAHCI
directory. C:\Windows is the location of the Windows directory. The command
line is:
msdinst.exe c:\AddAHCI\newmsd.inf c:\windows /force
Newmsd.inf contents:
