BSD/OS (originally called BSD/386 and commonly known as BSDi) was a commercial version of the BSD Unix operating system developed by Berkeley Software Design, Inc. (BSDi).
History In 1991 Bill Jolitz, working for the Computer Systems Research Group (CSRG) at UC Berkeley, a Unix research group financed by DARPA, wrote the six kernel files missing in the BSD Network release 2 (4.3BSD NET/2) . As part of the settlement of USL v. BSDi, BSDi substituted code that had been written for the University's 4.4 BSD-Lite for disputed code in their OS, effective with version 2.0. With the appearance of the 486, the "386" designation had become dated, and new versions of the system were released as "BSD/OS". The increasingly tight market for Unix-compatible softwares in the late 1990s and early 2000s hurt sales of BSD/OS. On one end of the market, it lacked the certification of the Open Group to bear the "UNIX®" trademark, and the sales forces and hardware support of the larger Unix vendors. On the other end, it lacked the negligible acquisition cost of the freely-licensed BSDs. The OS was purchased by Wind River Systems in 2001. Wind River discontinued sales of BSD/OS at the end of 2003, with support terminated at the end of 2004. | ||||||||
