SunOS 5.x was the OS. Solaris 2.x was the OS plus the windowing
system. So when you booted a system running Solaris 2.x, you were
greated with SunOS 5.x banenrs. Common usage was that SunOS 5 systems
were called "Solaris", and SunOS 4 systems were called SunOS,
regardless of how Sun labelled the distribution media.

The entry for Solaris largely agrees with my recollection of
events. It's been long enough that I'm a bit hazy on the details, but
there's nothing in it I know to be wrong.
