BSD/OS
BSD / OS (formerly BSD/386 ) is a commercial Unix operating system developed by Berkeley Software Design ( BSDI ) and comes from the BSD UNIX family. The development was stopped in 2003. BSD / OS has been used primarily in the area of Internet - server systems and recently developed and sold by Wind River Systems.
History
BSD/386
1991 left a group of BSD developers the University of Berkeley and founded the company Berkeley Software Design ( BSDI ) to develop a commercial UNIX operating system for i386 processors. Based on 4.3BSD Net / 2 was the operating system BSD/386. The first public version 0.3.1 was released in April 1992.
Shortly after the release of version 1.0 the developer Bill Jolitz left the group in March 1993 to develop the free UNIX operating system 386BSD, which later became an important basis for the free BSD derivatives FreeBSD and NetBSD.
Compared to competing products BSD/386 distinguished mainly by low royalties for the source code.
BSD / OS
After a dispute with the Unix System Laboratories ( USL ) for the rights to UNIX BSDI developed version 2.0 of their operating system based on 4.4BSD -Lite, which it contained no USL - based source code more. Moreover, the system in BSD / OS has been renamed so as not to limit themselves in the further development on the i386 architecture, and published in January 1995 as BSD / OS 2.0. One of the most important areas of the Internet was server part.
Although BSD / OS deposed by a well-developed SMP support and commercial support of the then free BSD derivatives, got it from this increased competition. The lack of certification by the Open Group led to decreased towards the end of the 1990s, sales figures and on.
Through a fusion of BSDI with Walnut Creek CDROM, then the largest distributor of FreeBSD and the Linux distribution Slackware, in March 2000, the offer of BSDI advanced. In April 2001, the company Wind River Systems eventually took over the rights to BSD / OS and FreeBSD distribution of BSDI and secured in turn, promote the development of FreeBSD. On 13 December 2003, the development and towards the end of 2004, the support of BSD / OS by Wind River Systems has been discontinued.
