Do you mean the extra 128K that you get from adding the chips (513-640K) or are you talking about the 128K that is wasted by having to use 256K chips to fill a 128K address space? As far I can tell there is no way to access the 128K above the 640K address space. Andy Silverman Internet: silver@eniac.seas.upenn.edu CompuServe: 72261,531
