Ugh... Solaris vs. SunOS naming rears its ugly head again.
The Solaris name first applied to SunOS 4.1.x along with the windowing environment and so on that was placed on top of it. SunOS 4.x and before was based on BSD. The Solaris name wasn't pushed really heavily. Indeed, according to the article I linked above, the Solaris name was constructed for the SunOS 5.x release, and then backfitted onto the SunOS 4.1.x products while SunOS 5 was in development.
With SunOS 5.x, Sun more heavily emphasized the Solaris name, with Solaris 2.0 corresponding to SunOS 5.0. When Solaris 2 came out, the SunOS name kinda drifted into the background. SunOS 5 / Solaris 2 was a big deal, as it was that version that shifted to a SysV base in contrast to the BSD base that had been under previous SunOS releases.
So, in terms of public perception, "SunOS" is the "BSD based version" and "Solaris" is the "SysV based version." But, in reality, both monikers have applied to both variants. Yay marketing.
