I too once tried an EMS simulator and it didn't work well. I since bought an intel AboveBoard (Real EMS memory) and it works quite well with MS Windows. Also, if you install himem.sys (in your config.sys file), windows can use the first 64k of extended memory as conventional (a quirk in the 80286 chip). Once you have EMS with windows, most windows applications reside mostly in this EMS memory leaving conventional memory alone (almost, they still require some conventional memory). I can get all of the windows supplied applications up at the same time and still have conventional memory left.
