Ghost vs WinPE and Dell 7040

I am having issues getting our new Dell Optiplex 7040s to cooperate with the ghost environment.  I can not seem to get the correct NIC drivers to work and get an IP.  Does anyone have a minute to help point me in the right direction?  I have a WinPE 5.0 Driver cab file from Dell but cant seem to add the drivers correctly to the ghost boot disk.
