BSD versions of Xenix

Hey all, is there B.S.D. version of Xenix out there?  Is there some other
B.S.D. Unix for the IBM PC?  Does anyone know what the difference is between
SCO Xenix and SCO Unix?  As some has pointed out to me, since SunOS is B.S.D.
and Xenix is SysV, developing on a Sun Sparcstation and porting to a Xenix
system might be more effort than its worth, so I'd like to explore any
BSD alternatives.
