Hoo boy! This is going to be interesting.

Okay, I am engaged in an effort trying to determine whether or not 
DOSEMU offers any hope as a path to porting a complicated legacy DOS 
application to more modern hardware as our stocks of available 
DOS-compliant hardware are diminishing to the danger point and 
replacements are no longer available.

To that end, I've downloaded DOSEMU onto a Ubuntu 10.04 system and it 
seems to work reasonably out of the box.

A very naive attempt to test the compatibility involved copying the 
executable in question to a drive accessible to DOSEMU, starting DOSEMU 
and running the application.

I start dosemu by simply typing the dosemu command, and a "DOS BOX" 
comes up in a different window.  All the normal stuff is doable.  But 
when I cd into the directory where I've placed my executable and then 
execute it, it blows up the DOS BOX (closes it) and in my original xterm 
window I now see:

OUCH! attempt to execute interrupt table - quickly dying

Well, I said this was a naive attempt.  But I have two weeks to get this 
to work.  Can someone tell me what this error message indicates and 
where I might possibly go to figure out how to fix it?

Thanks,
Steve Cohen
