Correct, I have a Sun386i here and it certainly does not run plain DOS/ 
But it does contain a 80386 CPU and the only thing that SunOS 4.0 was  
missing from getting it to run on a 386i was the low-lever driver  
stuff. This _was_ present in Interactive UNIX for 80386.

Yes. Still looking for a 486i. Two or three have been in use at a  
company here in the town I live in. Probably shredded :(
