JannasTo,
I tried this on DS 6.9 SP6 on a 2008R2 Server.
I downloaded the driver pack named PROWinx64.exe from here: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=21642
I extracted the files to a temp folder from PROWinx64.exe, using WinZip.
I imported this file: ...\PROWinx64\PRO1000\Winx64\NDIS62\e1d62x64.inf
The import completed successfully.
The following folder was added to the custom drivers folder:
...\Program Files\Altiris\eXpress\Deployment Server\Bootwiz\platforms\Winpe4\x64\Drivers\CUSTOM\Drivers\e1d62x64
HTH
