Re: EMM386 not installed - protected mode software already running.

[Steve Cohen <stevecoh1@comcast.net>]

To put my question a little more succinctly:

Is there a way to achieve the same results as the command

DEVICE=C:\DOS\EMM386.EXE frame=none x=C000-C7FF x=E000-E7FF

through dosemu.conf entries without loading the EMM386 driver?  I don't 
know why these particular switches are necessary, but the previous 
system is my starting point here.

If there is a better way to handle these issues, I'm willing to hear them.
