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.
