A project taking an operating system from Hello World to a fully functional, desktop worthy distribution.1 weekly downloads
The Trion Object Oriented Operating system is an OS that is designed to meet the needs for the 21st century, with a kernel written in C++ and modelled in UML, and lots of features. The project is run by a team of OSDev.org community members.6 weekly downloads
libosdk stands for operating system development kit, which is simply a library containing low-level architecture dependent assembly procedures you can use to develop your own os without using assembly language or even know about it.1 weekly downloads
tOfuS is an OS kernel with framework capabilities, in order for everyone to experiment on it. (was: A Music-Production oriented Operating System, for use in recording studios and live performances as a mixing desk and user-programmable DSP).1 weekly downloads
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.
A computer operating system.1 weekly downloads
This was a personal research project for me. I never made any later commits, so most of the code is on unreadable floppy disks. I might tinker with the idea of a toy operating system someday.
The Fecundity Project has the purpose of creating a streamlined AMD64 based Operating System. We will hopefully create a stable and secure operating environment, and to investigate orthogonal persistence.1 weekly downloads
The Isis OS Project Is a Controlled Project to Develop An Advanced Modern Operating System!
Exploring the possibilities of doing an Operating System completely different than all of the existing ones. Instead of basing it upon concepts that are 40 years old, design it from the ground up object oriented, peer-to-peer, and for security.1 weekly downloads
COS - Component-based Operating System3 weekly downloads
C-BIOS is an open source BIOS for MSX computers. C-BIOS can be shipped with MSX emulators so they are usable out-of-the-box. This project aims to improve C-BIOS by fixing incompatibilities with the MSX BIOS and the development of a Disk ROM.39 weekly downloads
The aim of this project is to develop a modular operating system for the i386 architecture, where each device driver, file system, etc, will be a module that can be loaded and unloaded at run-time from the system.1 weekly downloads
This was originally an OSdev group, but since as members disbanded, I'm continuing to provide various implemenatitions of software, hardware, operating systems, libraries, and some stuff related to math and physics.3 weekly downloads
Fortress OS is an open source modern multitasking operating system. Intel IA-32 386 compatibility. Fortress is clean implemented from scratch. Fortress is still in early stage ( current state at the end of plan 2 ) and needs huge work.1 weekly downloads
Genesix is a kernel for the x86 (386+) architecture. Written mostly in C and assembly, it is targeted to learning kernel architecture and development essentials.
ArchOpen is a project aimed at providing a fast, light and free operating system and applications for portable multimedia devices based on TI DM&DSC chips. It currently supports a lot of Archos multimedia devices (Gmini402,AV400,...).
Simple and very modular Operating System to be used also in a provided simulator.
KenaxOS, originally named AOS (An Operating System), is a project to design a new OS that is developer friendly (having an excellent interface for software development), written mainly in C and some Intel syntax Assembly.1 weekly downloads
