RE: E7450 SCCM Build
For Microsoft Deployment Toolkit (MDT), which I believe works similar to SCCM, I had to import the drivers for Windows 8 and Windows 8.1 even though I'm imaging Windows 7 x64 PCs. I suspect that the WinPE driver included in the Windows 7 files was older than what was required. Once I imported the Windows 8 and Windows 8.1 drivers WinPE, then rebuilt and imported my boot image, it connected fine.
- Download the file from here: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=0J8HP&fileId=3493709081&os...
- Run the downloaded .EXE file and select Extract (give the program a temp folder to use)
- We're only imaging 64bit so I open the "\Drivers\production" sub-folder in the temp folder and delete any "-x86" folders
- Import the remaining drivers and rebuild your boot image
