Projects
This page maintains a list of academic, personal, and small non-commercial operating systems. For information regarding commercial or main-stream operating systems visit Wikipedia.
The type of operating systems listed here have a high mortality rate. This list was off-line from 09-04-2004 until 06-17-2006 and during that time 112 of 213 operating system projects disappeared from the internet leaving only 101(submitted). Looking at how often these projects are started by using the OS Project Announcement forum we can see that between 11-24-2004 and 6-21-2006 around 68 projects were announced(many of which disappeared before being added here). The current total is 133 projects. Please help keep this list current by correcting it yourself if you have a login id or by posting a message on the OSDevWiki forum pointing out the incorrect entry.

- AtlantisOS - AtlantisOS is designed from the ground up to include the most efficient mechanisms and modern techniques to construct and maintain the operating system. Notable differences with current other operating system projects is that the code is released into the public domain, drivers are only made when the base layers are fully in place and nothing is made with the base layer half implemented or only stubbed. This also explains the lack of progress, although it can boot up and detect a number of PCI devices by now. Releases are not often, but the code on SVN is usually stable and more capable than the last release.

B
- BAB - BABy (Basic Abstraction Block) is a 50Kb IA-32 microkernel for DOS. It manages the x86 hardware interaction in a manner similar to Windows' HAL. BABy exports an extensive API via INT's 15h, 2Fh, and 31h. It is free LGPL'd software with full source. The API provides services in 5 categories: I/O control, PMode domains, PMode services, Memory mgmt, and VM86 mode. DPMI services via BAB are not yet complete. BABy can be used to provide PMode services to our shareware multiuser O/S, VMiX x86 (listed velow). Distribution includes binaries, sources, makefiles, samples and API docs.

- BOS - BOS is a new 32-bit Operating System designed with DOS in mind. That means no protection, no multitasking, no paging, and no to a lot of other things often related with new 32-bit OS:es. But despite it's lack of protection it will still be a modern OS with native support for CD-ROM/BURNER, DVD, USB, most filesystems, up to 4gb of memory etc. This is a OS for all those people that miss the days of DOS programming.

- DexOS - DexOS is a 32bit, asm OS, based on the idea, that it would be cool to have a OS based on a console type OS, but instead of running on a xbox or DS, it would run on a x86. From the start, as you would expect from a OS based on a game's console OS, optimizing for speed has been of paramount important in the over all design. To this end there's no virtual memory, paging, and only a single process is allowed (though that process can spawn multiple threads). The program runs in ring0, you have direct access to all hardware (including CPU and graphics). Memory allocation is the responsibility of the app--there's no front-end memory allocation. The entire OS will fit into less than 100k.

- Horizon - Horizon is a research Operating System. It is written for the i386 processor family, using C (gcc) and some Assembly (nasm). Its main goal is to develop a natively network-integrated structure, so that I/O operations (both local and network ones) happen in the same manner. This way every Horizon node on the Internet (or in a LAN) can communicate natively by means of a Network File System.

- MenuetOS - MenuetOS is a fully 32 bit assembly written graphical operating system. Menuet supports 32 bit x86 assembly programming as a faster and smaller system footprint. Menuet has no unix roots and the basic system is meant to be a clean asm based structure. Menuet isn't based in any particular operating system, since the idea has been to remove the extra layers between different parts of software, which complicate programming and create bugs. Menuet's application structure is not specifically reserved for asm programming since the header can be produced with practically any other language. However, the overall application programming design is intended for easy 32 bit asm programming. The GUI is extremely easy to handle with assembly language.

Exceptions and IRQs which need their own stack and can run across process task switches are handled through task gates in IDT and others are handled through normal interrupt gates. The aim is to have its users a pleasant experience using MOS.

It is available from Native Oberon and a more current multiprocessor version can be found here: BlueBottle. Note that some stuff on these pages appear outdated, but it appears to be more the problem of keeping the Web-pages as current as the System. An active mailing list is here: Oberon Mailing List Archive. More current and in depth documentation is included in the systems, although you (sorrily) have to master their (partially) unconventional user-interface before you can access the documentation. A kind of an henn and egg problem.

- RevolutionOS - RevOS is a project dedicated to creating an OS that stores a minimal amount of information on the user's system, and instead keeps all documents and applications on a remote server, allowing for access from virtually any system. Plans are to create a CSS/XML based GUI on top of an ASM/C/C++ kernel. Project will be considered semi-open source, as the main kernel will remain closed, but all applications, API's, and modules will remain open to the community. The project is currently halted, and we'll be restarting from scratch as soon as a few developers get onboard. We aim to eventually compensate developers via funds from merchandise and donations, but otherwise the software will most likely be distributed free of charge.

- Sendla Operating system - The Sendla OS is an os targeted at having major stability, it is also targeted at running: Windows programs, Mac os programs, Linux programs, DOS programs, Beos programs, Unix Programs and many more. Sendla OS is going to have a major security system running, this will not, like windows, prevent the user himself from being restricted, an included antispyware engine will also be running. We are also adding 3 modes of use with it for ease of use without restriction ( Beginner, Advanced and Command). Beginner is just simply a click to start your program type interface. Large buttons with pictures of their software on them will be used to make an extremely simple interface. Advanced mode will be more like the current Windows GUI, but much more stable and enhanced. Command mode as youve probably guessed by now is a DOS like shell. Type the command to run somthing, this has a similarity to the restriction free linux.

- SysPak OS - SyaPak OS is a microkernel based multiprocessor, multitasking, multithreading operating system for the IBM-PC Intel i386 systems. It is developed in Department of Computer Science of Bahahuddin Zakariya University, Multan Pakistan, under the kind supervision of Dr. Aman Ullah Khan. SysPak OS is a operating system with an emphasis on design and portability. It is largely implemented in C/C++, with a small amount of assembly. Currently, the system is mostly a kernel with a minimal amount of user space libraries and applications. Thus far, most of the work has been put into the kernel and other underlying support. As a result the system isn't that interesting from an end-user point of view (no gui, simple commands on a command line). Full documentation is available.

The new architecture includess two main components. The system layer is managed by BABy (Basic Abstraction Block). It manages the hardware interaction in a manner similar to Windows' HAL. The BABy microkernel exports an API that can be used by other O/S's. The second component is the VMiX O/S layer, it manages text and graphical processes.
