When you create a Sysprep.inf file using the Setup Manager tool, the OemPnpDriversPath registry key may be written incorrectly.

The Graphical portion of Sysprep (referred to as Mini-setup Wizard) is not interrupted, but devices requiring Original Equipment Manufacturer (OEM) drivers are not installed.


This issue can occur if the OemPnpDriversPath registry key is written to the wrong path.


To work around this issue, edit the Sysprep.inf file and change the OemPnpDriversPath line to the following:

OemPnpDriversPath = "Drivers"


Microsoft has confirmed this to be a problem in Microsoft Windows 2000.


The OemPnpDriversPath registry key is used to locate Plug and Play (PnP) drivers supplied by vendors to be installed during setup.

When you create the Sysprep.inf file using Setup Manager, you can specify the location of Plug and Play drivers on the Additional Files and Folders page. When you select the location of these files, such as c:\drivers, the OemPnpDriversPath value data is written as follows:

OemPnpDriversPath = C:\drivers

Windows automatically prepends the value data with %SystemDrive%, so the incorrect path %SystemDrive%\C:\drivers is written to the following registry key:
