You're thinking of SunOS, which started out as 4.2bsd.
Solaris derived mostly from the USL code base; it was an attempt to
re-unify the Unix world by pulling together the BSD and USG forks.

That's not true. It is true that they obtained TCP/IP networking
support from BSD, but that came later (not "originally"). Use of
BSD networking software does not suffice to call something "a fork
of the BSD source code".

That's also not true.

But VxWorks, LynxOS, and other RTOSes are not UNIX-like. They often
contain compatibility layers to provide POSIX support, but the underlying
implementation is quite different.
