Just reading your reply again. Are you saying it has enough memory on the board, without using a daughter board? I did see lots of memory on the main board, but assumed it was video memory. I did try removing the daughter board altogether at one point, but it still didn't work. :-( I wish I had a logic analyser. Regards Rob
