The big limitation with the DoC is that is has just a 512 byte array that can be used as memory mapped ROM. It that sapce you either need to pull the cache as ram trick, or actually enable ram. There is just enough more work enabling DDR memory that it probably will not work. I haven't even gotten close to doing the cache as ram trick on the Athlon. The problem may was probably that I hadn't stopped my second cpu when I tried. After I had linux up I had some caching of rom areas going so I think it was just attempting it wrong... Eric
