I do not need a solution (just sharing information)
I just wanted to post this in the forum, since it is currently in the Articles section. My article on setting up a WinPE3.1 partition for use in GSS2.5.1 has been approved! by no means is this a fool proof, 100% replacement, but it is a nice start for anyone wanting to see how this could be done.
Thanks to EdT also for this, since he is very helpful in the forums!
