If you do not, or cannot, use a device such as a USB key to load a driver after WinPE has started,
Use the following process to add the driver to the Plug-in Offline Client image and then re-create the Plug-in Offline Client image with the added driver.
To do this, you must have Windows Automated Installation Kit for Windows 7 installed, the applicable *.inf file, a program capable of extracting an ISO image, and a method for repackaging the ISO as a bootable image or bootable CD. The following steps are based on Windows 7; these steps might differ depending on your environment.
The following items are required for this procedure:
Windows Automated Installation Kit (AIK) for Windows 7 (obtained via download)
32-bit version of a Windows 2003, Windows 2008, Windows 2008 R2, or Windows 7 system Plug-in Server “.npk” file (obtained via download)
A writable DVD and CD-ROM drive
A blank DVD and CD
DVD- and CD-generation software
1. If it is not already installed, install the Windows Automated Installation Kit for Windows 7 on a Windows 7 machine.
2. Extract the Plug-in Offline Client “.iso” file to a temporary directory (for example, c:\vaultos).
3. To access the Deployment Tools Command Prompt, click Start > All Programs > Microsoft Windows AIK, right-click Deployment Tools Command Prompt, and select Run as Administrator.
4. To mount the image into a temporary directory (c:\mount), type the following at a command prompt:
dism /Mount-Wim /wimfile:c:\vaultos\SOURCES\boot.wim /index:1 /MountDir:c:\mount
5. To inject the driver (located in c:\temp\driver\xxxx.inf), type the following: dism /image:c:\mount /add-driver /driver:c:\temp\driver\<xxxx.inf>
6. To save your changes and dismount the image, type the following: dism /unmount-wim /mountdir:c:\mount /commit
7. Repackage the c:\vaultos directory into a bootable ISO or CD Plug-in Offline Client image that contains the added driver.
