If you run a DOS program in a DOS emulator, you probably want to emulate some of the I/O port accesses. I think that's io_emulation all about, right? A DOS emulator would catch the exception and either add permission to the task and allow the access, deny the access, or emulate it. Thanks, Marcus -- `Rhubarb is no Egyptian god.'
