AtheOS – a free and open-source desktop operating system initially intended as an AmigaOS clone. AtheOS currently run on Intel, AMD and other compatible processors and support the Intel Multi Processor architecture.

AtheOS is not meant to be a new Unix clone (like Linux and *BSD) but a new clean desktop OS. It does support large parts of the POSIX standard and hence are able to run most of the UNIX CLI tools and it comes with a standard UNIX shell (BASH) but this does not compromise anything in AtheOS as a desktop OS. AtheOS have a integrated GUI that works in conjunction with the kernel and various other components to create a complete and consistent system.

The AtheOS GUI consists of two main components: An application server and a dll providing a C++ interface between the server and the application. The GUI is therefore programmed through a C++ API providing windows containing a hierarchy of widgets that all have their own graphical environment.

The kernel was written from scratch. It supports SMP (Symmetric Multi Processing), has a built-in network TCP/IP stack.

The system was under development between 1994 and 2001 by Kurt Skauen.

There is a fork based on AtheOS called Syllable.

Syllable – an open-source and independent developed operating system for Pentium and compatible processors. It was forked from the stagnant AtheOS in July 2002, which was initially as an AmigaOS clone.

The main keys of Syllable Desktop:
– Operating system optimized for desktop computers.
– Easy to use graphical work environment with consistent, simple but powerful interface. Text console emulation is available as extra within the graphical environment.
– High response speed to user input, even under load.
– Fast start-up (under ten seconds on modern computers) and shut-down (around five seconds).
– Based on the AtheOS operating system. Modular. Multi-user. Memory protection. Pre-emptive. Kernel threading. Excellent support for SMP and multi-core systems. Originally inspired by AmigaOS.
– It has a native web browser (Webster which is WebKit-based), email client (Whisper), media player, IDE, and many more applications.

– Runs on Intel-compatible PCs in 32-bits mode.
– Minimum requirements are a Pentium processor and 32 MB memory. (To use the web browser you need some more memory, and 64 MB is needed for the Live CD).
– Base installation takes around 250 MB disk space, including a collection of applications.

Syllable Server is a small operating system built to be used as a server, using the Linux kernel. Syllable Server is suitable as a virtualization platform for running other operating systems using the QEMU emulator.

– Runs on Intel-compatible PCs in 32-bits mode.
– Minimum requirements are: a 486 processor and 16 MB memory.
– Base installation takes around 480 MB disk space.

Developers: Kristian Van Der Vliet, Kaj de Vos, Rick Caudill, Arno Klenke, Henrik Isaksson.
The latest version of Syllable Desktop 0.6.7 was released in April 2012.
