BSD/OS (originally called
BSD/386 and sometimes known as
BSDi) was a proprietary version of the
BSD Unix operating system developed by
Berkeley Software Design, Inc. (BSDi).BSD/OS had a reputation for reliability in
server roles; the renowned Unix programmer and author
W. Richard Stevens used it for his own personal
web server for this reason.
(1)History
BSDi was formed in 1991 by members of the
Computer Systems Research Group (CSRG) at
UC Berkeley to develop and sell a proprietary version of BSD Unix for
PC compatible systems with
Intel 386 (or later) processors. This made use of work previously done by
Bill Jolitz to port BSD to the PC platform.BSD/386 1.0 was released in March 1993. The company sold licenses and support for it, taking advantage of terms in the
BSD License which permitted use of the BSD software in proprietary systems, as long as credit was given to the University. The company in turn contributed code and resources to the development of non-proprietary BSD operating systems.In the meantime, Jolitz had left BSDi and independently released an
open source BSD for PCs, called
386BSD.
BSD/386 licenses (including
source code) were priced at $995, much less than
AT&T UNIX System V source licenses, a fact highlighted in their advertisements.
(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 release for disputed code in their OS, effective with release 2.0. By the time of this release, the "386" designation had become dated, and BSD/386 was renamed "BSD/OS". Later releases of BSD/OS also supported
Sun SPARC-based systems.The marketing of BSD/OS became increasingly focused on
Internet server applications. However, the increasingly tight market for
Unix-compatible software 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 force and hardware support of the larger Unix vendors. Simultaneously, it lacked the negligible acquisition cost of the open source BSDs and
Linux. BSD/OS was acquired by
Wind River Systems in April 2001
(3). Wind River discontinued sales of BSD/OS at the end of 2003, with support terminated at the end of 2004.
