I have a poweredge 2950 with onboard broadcom nics and a dualport intel pro/1000 PT adapter.
When i right double click the broadcom nic from devicemanager i get the "advanced" tab where i can configure things like jumbo frames.
But when i click the intel adapter i dont get any proset tabs so i can configure jumbo frames.
The strange thing is, after a install the first time i double click the windows appears and closes right away.
I have tried to install the drive with dxsetup.exe
