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

Overview
A Become Operating Body, or even BeOS, was foremost written inside 1991 to start in BeBox hardware. Unlike more operating systems of the period, BeOS was written to work as a GUI-based operating system. Optimized for digital media function, BeOS fill up utilise of multiprocessor systems by utilizing modular I/O bandwidth, permeating multithreading, pre-emptive multitasking & the customised 64-bit journaled file system known as BFS. the BeOS GUI was developed on the lesson of clarity & a uninfected, unlittered project. A interface API was written in C++ for ease-of-programming. It has POSIX compatibility and access to the command line interface through the Bash shell.

At the start intentional to dog in custom-made BeBox hardware, BeOS was later reach do in PowerPC-based processors with a hope that Apple Computer would purchase or even license BeOS as a replacement for its so senescent Mac OS. But, instead of BeOS, Apple's board of directors decided NeXTSTEP was a better selection & purchased NeXT in 1996, which also brought Apple co-founder Steve Jobs back into the stack. To farther complicate matters for Become, Apple refused to disclose architectual facts all about its G3 line of computers—information critical to making BeOS act on the latest devices from either Apple.

Due to Apple's aggressive moves & a mounting debt of Be Inc, BeOS was soon ported to the x86 platform with its R3 release. Through a late 90s, BeOS managed to produce the niche of hardcore followers, however the company failed to be solvent. As a endure-ditch effort to increase interest in the failing operating rules, Become Inc. discharged the stripped-stripped, however loose, copy of BeOS R5 called BeOS Private Edition (BeOS PE). BeOS PE can be began from either in Microsoft Windows or Linux, & was meant to nurture consumer interest around its product and give developers something it can tinker inside.

Become Inc. besides discharged the stripped-stripped version of BeOS for Internet Appliances (BeIA). Unluckily, BeOS PE & BeIA proved to become as well little as well late, & within 2001 Be's intellectual property was sold to Palm, Inc. BeOS R5 is considered the last official version, but BeOS R5.1 "Dano", which was under development before Be's sale to Palm, was leaked to the public shortly after the company's demise.

Despite a prevent of Exist as Inc. BeOS remains popular among hardcore followers. A BeOS community however develops loose software package & has potentially freed patches, drivers & various updates to BeOS. A independent source of BeOS-related package may be incurred at [http://www.bebits.com BeBits.com].

A BeOS interface was notable at a instance for existence nigh entirely unthemeable, potentially by using third person hacks. When Mac OS X is now likewise locked, a BeOS theme of yellow, changing length tabs on the top of windows, and comparatively plainly grey interface widgets was enforced. This UI remained comparatively unchanged from either 1995, but got been entirely overhauled per instance of the leaked Dano release. An easter egg within the OS allowed changing the titlebar look-&-sense to two or three others, & in Dano, this got been reach exist as the feature permitting changing of the title bar & scrollbars. There are no more interface widgets can be changed.

A patently BeOS R5 GUI is ordinarily cloned, either when a independent UI, like within TriangleOS, or as a theme, like for SkyOS or GNOME.

Projects to recreate BeOS

BeOS was swell loved by numerous humans, & a BeOS user base was disappointed whenever Become, Inc. failing commercially & there is no farther sweetening of the operating formulas would exist as conceivable. When of 2002, a few projects own formed to independently recreate BeOS inside varying ways, using a eventual goal of so continuing in which Become Inc. left dispatch. To assure that a OS just can not become "taken away" fromA Become community over again, & to attract a efforts of volunteer computer programmer, these projects come a lot free software / open source software. A profits of similar projects to produce loose package operating systems has been proved per GNU project and various free software system BSD-based projects. the modular nature and severity of a original BeOS facilitates recreating the operating body a piece at once, inserting the new coded modules into a working BeOS rules to line 2 text compatibility. Finally completely of the "servers" (interworking modules of code) come to become replaced using original, freely commissioned code.

Projects to continue BeOS

YellowTAB is believed to have a rights to utilize a bare BeOS R5.I sourcebase, but not the BeOS trademark, & presently distributes a release (as of June 9 2005) of the OS project known as Zeta. YellowTAB has never stated their legal position within regards to the BeOS code-base (perchance for contractual reasons), & because of this, has created a great total of contention & skepticism in the Exist as community.
