Thanks for your information :-)

I tend to think that the "-s" switch merely calls "sudo" to get admin 
privileges => there's no point to using -s when dosemu is already run 
by the root.

As for "it works in X but not in console", my explanation is that 
under XWindows, the dosemu VGA graphics runs entirely in an emulator, 
whereas at the text-mode console, dosemu tries to access the graphics 
hardware directly, which fails for some reason...

Maintaining X in a diskless "boot anywhere" setup is not an option 
for me. Effectively it defies the purpose of my Linux+DOSEMU 
adventure, an important part of which is seamless simplicity :-)

The one point I forgot to mention is that I've tried dosemu 1.4.0.0-
release and yesterday's latest from SVN and both behave the same.
I compile them for i486-pc-linux-gnu for maximum compatibility.
