I am trying to PXE boot some Dell M710HD blades that use the Broadcom 57711 NetXtreme II 10GB NICs and am not having much luck. The blades will PXE boot, contact WDS and present me with the screen to select the boot image I want. When I select the appropriate boot image, it copies it down but when it goes to load it and start WinPE, I do not get an IP address from DHCP because no driver for the 557711 NICs get loaded. I have downloaded the drivers for the 57711 from Dell but when I try to import them...the import fails. I thought the drivers for the Broadcom 57711 were in WinPE 3.0, what version of WinPE is used in WDS that is part of Windows 2008 R2 SP1?

I got the drivers injected using the command-line tool DISM and now everything is working. Not sure why I could not add them through the GUI.
