Solved the problem of megadots with dosemu. I needed to allot some kilobytes for dpmi. It works, though asap was being a bit flaky. At least this problem is clearly addressed in the dosemu howto! the only drawback now is that it is apparently definitely a security no-no to run dosemu as root with dpmi working, so I need to solve the /var/lock problem, as does Greg just because he can't even run it as root.
