Well WinPE 2.0 by default copies it self to ram drive then runs from the ram drive. So if you PE CD is larger than the free amount of ram it can not load all of the drivers because it ran out of memory. I wish there was some error message when something like this happens. Your can try an make the PE CD smaller by removing stuff from your image or run from CD and not a RAM drive(this option is very slow). I am not sure how to do either one of those. I have just been adding more memory to the units that have less than 256.
