Download CenterHi Christoph,
I apologize for the misinformation on this page. The bad news is that the uncertified driver you need is not in the latest software packages available today. The good news is that the uncertified driver you need should be available for download within the next few weeks, possibly even a few days from now.
The drivers you need will be part of the version 17.4 package. The CD file is usually available first, so you can watch for a version update at http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=21228.
Or, you can also subscribe to an RSS feed for downloads associated with the Intel(R) PRO/1000 PT Dual Port Server adapter at http://feeds.downloadcenter.intel.com/rss/?p=2248&lang=eng. That way your feed would be updated when the new version is available for download.
Again, I am sorry for the inconvenience of having the wrong information on the support page.
