BeOS is an operating system for personal computers which began development by Be Incorporated in 1991.

History

The Be Operating System, commonly refered to as BeOS, was first written in 1991 to run on BeBox hardware. Unlike other operating systems of the time, BeOS was written from the ground up to be a GUI-based operating system. Optimized for digital media work, BeOS places makes full use of multiprocessor systems by utilizing modular I/O bandwidth, pervasive multithreading, preemptive multitasking and a custom 64-bit journaled file system known as BFS. The BeOS GUI was developed on the principles of clarity and a clean, uncluttered design. The interface API was written in C++ for ease-of-programming. It has POSIX compatibility and access to a command line interface through the Bash shell.

Initially designed to run on custom BeBox hardware; BeOS was later extended to run on PowerPC-based processors with the hope that Apple Computer would purchase or license BeOS as a replacement for its then aging Mac OS. However, instead of BeOS, Apple's board of directors decided NeXTSTEP was a better choice and purchased NeXT in 1996, which also brought Apple co-founder Steve Jobs back into the fold. To further complicate matters for Be, Apple refused to disclose information about its G3 line of computers – information which was critical to making BeOS work on the latest hardware from Apple.

Due to Apple's aggressive moves and the mounting debt of Be Inc, BeOS was soon ported to the X86 platform with its R3 release. Through the late 90's, BeOS managed to create a niche of hardcore followers, but the company failed to become solvent. As a last-ditch effort to increase interest in the failing operating system, Be Inc. released a stripped-down, but free, copy of BeOS R5, or BeOS Personal Edition (BeOS PE). BeOS PE could be started from within Microsoft Windows, and was intended to nurture consumer interest in its product and give developers something they could tinker in.

Be Inc. also released a stripped-down version of BeOS for Internet Appliances (BeIA). Unfortunately, the free release of BeOS and BeIA proved to be too little too late, and in 2001 Be's intellectual property was sold to Palm, Inc. BeOS 5 is now considered the last version, though a substantial upgrade was in the works before the bankruptcy.

Despite the end of Be Inc. BeOS is popular amongs't many of its hardcore followers. The BeOS community still develops free software and has even released patches, drivers and various updates to BeOS. The main source of BeOS-related software can be found at BeBits.com.

Projects to recreate BeOS

BeOS was well loved by many people, and the BeOS user base was disappointed when Be, Inc. failed commercially and no further enhancement of the operating system would be possible. As of 2002, a few projects have formed to independently recreate BeOS in varying ways, with the eventual goal of then continuing where Be Inc. left off. To ensure that the Be community does not again "lose" its OS, and to attract the efforts of volunteer programmers, these projects are all open source (in much the same way that Linux, BSD, and GNU set out to create open source equivalents of UNIX). The modular nature of the original BeOS facilitates recreating the operating system a piece at a time, inserting the newly coded modules into a working BeOS system to test compatibility. Eventually all of the "servers" (interworking modules of code) are to be replaced with original, freely licensed code.

Projects to continue BeOS

• YellowTAB is believed to have the rights to use the unfinished BeOS R5.1 sourcebase, but not the BeOS trademark, and currently distributes a pre-release of the OS project called Zeta. YellowTAB has never stated their legal position in regards to the BeOS code-base (perhaps for contractual reasons), and because of this, has created a great amount of controversy and skepticism in the Be community.
