- Not right now. To run DOS in Unix like Linux has and Interactive Unix
- has (VP/ix), the processor has to kick in V86 mode.

- Basically, all they need to do is trap interrupt calls to the BIOS and
- emulate the service in some way. V86 mode on the 80386 and above
- allows you to do this in a relatively coordinated fashion.
-
- you won't be running MS-windows or anything that uses 386 specific code
- though. You're limited to 16-bit instruction set.
