Using this Driver With Windows Deployment Services (WDS)

We are aware that this driver may not import into Windows Deployment Services on Windows Server 2008R2 and Server 2012. As a work around, you will either need to install the driver manually into deployed systems, or use WDS to capture and deploy your own Install image which already has the driver included.
