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.

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. The Computer Systems Research Group ( CSRG) was a research group at the University of California Berkeley that was dedicated to enhancing AT&T Unix The University of California Berkeley (also referred to as Cal, Berkeley and UC Berkeley) is a major research university located in Berkeley IBM PC compatible computers are those generally similar to the original IBM PC, XT, and AT. This made use of work previously done by Bill Jolitz to port BSD to the PC platform. William Frederick (Bill Jolitz (born 1957 commonly known as Bill Jolitz, is best known for developing the 386BSD Operating system from 1989 to 1994

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. BSD licenses represent a family of Permissive free software licences. 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. Open source is a development methodology which offers practical accessibility to a product's source (goods and knowledge 386BSD, sometimes called " JOLIX " is a free BSD Unix Operating system for PC compatible computer systems based

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. In Computer science, source code (commonly just source or code) is any sequence of statements or declarations written in some Human-readable Before proposing a merge request please see Talk and see if the merger you propose has recently been made and Unix System V, commonly abbreviated SysV (and usually pronounced though rarely written as System 5 was one of the versions of the Unix Operating system ^[1] As part of the settlement of USL v. BSDi, BSDI substituted code that had been written for the University's 4. USL v BSDi was a Lawsuit brought in the United States in 1992 by Unix System Laboratories against Berkeley Software Design, Inc and the 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. Sun Microsystems Inc ( is a multinational vendor of Computers computer components Computer software, and Information technology services SPARC (from Scalable Processor Architecture is a RISC Microprocessor Instruction set architecture originally

The marketing of BSD/OS became increasingly focused on Internet server applications. The Internet is a global system of interconnected Computer networks However, the increasingly tight market for Unix-compatible software in the late 1990s and early 2000s hurt sales of BSD/OS. A Unix-like (sometimes shortened to *nix) Operating system is one that behaves in a manner similar to a Unix system while not necessarily conforming 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. The Open Group is an industry Consortium to set vendor- and technology-neutral open standards for Computing infrastructure Simultaneously, it lacked the negligible acquisition cost of the open source BSDs and Linux. Linux (commonly pronounced ˈlɪnəks BSD/OS was acquired by Wind River Systems in April 2001^[2]. Wind River Systems Inc is a publicly owned company providing Embedded systems development tools for embedded systems Middleware, and other types of Software Wind River discontinued sales of BSD/OS at the end of 2003, with support terminated at the end of 2004.
