Thanks eric. I cannot judge which is better, though. Are there any problems using 'sources' pc kernel, anyone? Please put those notes on the top page of your atom site. Your pcpae kernel has never problems here so far. However, I wonder whether I need so much memory in my Plan9.☺ My machine has only 4GB memory though. How about libaml, libfis? Why they are added? Or splitted from what? Kenji
