Novell's Entry into the UNIX Market
The UnixWare 1.0 release of UNIX was released in 1992 as a joint venture between Novell and USL under the name Univel. Novell completed the acquisition of USL in 1993, and both USL and Univel were merged to form the Novell UNIX Systems Group.
UnixWare 1.0 was based on SVR4.0. This was followed by UnixWare 1.1, which was based on SVR4.2. With the introduction of UnixWare 2.0, the kernel (SVR4.2MP) had changed significantly, introducing SMP support and kernel threads.
In 1993 Novell transferred the rights to the UNIX trademark to the X/Open organization (now the Open Group). Two years later they sold their UNIX business to SCO who in turn sold a dwindling UNIX business to Caldera in 2001.
