Deployment Solution

When adding a Create Disk Image task for a Vista image and modifying the advanced sysprep properties, selecting "install additional drivers" and adding a path will allow drivers to be injected into the image.

Click to view.

However, the problem with this, is that you will be prompted for unsigned drivers after pulling down the image with a Distribute Disk Image task. To get around this, I created a custom InstallDrivers.xml in the Deploy directory:

<?xml version="1.0" encoding="utf-8"?> 
<unattend xmlns="urn:schemas-microsoft-com:unattend"> 
  <settings pass="offlineServicing"> 
    <component name="Microsoft-Windows-PnpCustomizationsNonWinPE" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
      <DriverPaths> 
        <PathAndCredentials wcm:action="add" wcm:keyValue="0"> 
          <Path>\\%DSSERVER%\eXpress\Drivers/Path> 
        </PathAndCredentials> 
      </DriverPaths> 
    </component> 
  </settings> 
  <cpi:offlineImage cpi:source="wim:c:/vistadist/install_x86.wim#Windows Vista BUSINESS" xmlns:cpi="urn:schemas-microsoft-com:cpi" /> 
</unattend>

Then, I have a task run pre-boot in WinPE automation mode to handle the driver injection "offline" using pkmgr.exe from the WAIK:

REM Add Vista drivers offline

REM Token Replacement for InstallDrivers.xml file
REM ReplaceTokens .\Deploy\InstallDrivers.xml .\Deploy\temp\%COMPNAME%.xml

REM Run pkgmgr.exe
.\WAIK\Tools\%PROCTYPE%\Servicing\pkgmgr.exe /o:"c:\;c:\windows" /n:".\Deploy\temp\%COMPNAME%.xml"

Del .\Deploy\temp\%COMPNAME%.xml /Q
