Mattise is a simple hobby operating system designed to run fast on 32-bit PCs. A newlib port will be released soon for developers to write their own programs for Mattise.
IA-32 operating system with Java virtual machine embedded into the ker
IA-32 operating system with Java virtual machine embedded into the kernel. Part of the kernel is written in Java. Only Java applications can run on this system. jArt VM is a stand-alone virtual machine that interprets java bytecode. It can run under Linu
MGOS3 a small OS currently under development, MGOS3 is aimed at the IA-32 architecture, currently it is distributed in the form of .x COFF executables, which are used with a 1_44 floppy image for simulation or writing to a floppy disk for execution
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.
AVR32-FreeRTOS project is dedicated to the port of the FreeRTOS real-time kernel to the Atmel AVR32 32-bit AT32AP700x processor familly . For uc3 version port of the FreeRTOS, please check www.freertos.org !
Protical5 - A 32-bit hobby OS for the x86 processor. Coded in assembly and C, this project aims for no compliance with any OS standards or special performance. A project based solely on the ideas of having fun and learning.
uDOS is a free operating system built on the FreeDOS kernel with DJGPP. uDOS provides an integrated suite of features inluding Perl, Python, etc., as well as a Watt-32 based networking environment and ELF library support. Can be run live from CD image.
UnderHook is a 32-bit x86 non-virtual function hooker. The library has the ability to dynamically intercept arbitrary calls to functions in any process and reroute them to a number of user defined functions.
This project focus on creating an original alternative 32-bit operating system for Intel 80386 compatible processors made in NASM (The Netwide Assembler). The main goal is to be, a simple and pratical plataform for developpment and plug in extra codes.
Blueport is an italian Open Source 32-bit operating system ... This project has temporarly moved to Gna.org: <a href="http://gna.org/projects/blueport">Blueport project</a>
512DevOS is a GPLed operating system that runs on 16 and 32 bit x86 compatible computers. The kernel and shell fit in 512 bytes and occupy only the first sector of a floppy disk.
Routix es un mini sistema operativo para arquitectura IA-32 el cual posee como principal finalidad ser lo mas claro y escalable posible, con el objeto de ser facilmente extensible hacia el cumplimiento de diferentes tareas.
AVOS is an advanced Real-Time 32-bit operating system that will work in any 80386 & above architecture pc's. AVOS employs a message passing scheme. The project has two main parts - The booting phase and kernel development. It is written in C and 8086 ASM.
Project to create a new microkernel for AdaOS. Intended to be especially suited to Ada programming language, but will have pragmatic design which is actually language neutral. Will be practical, general-purpose, and secure, but otherwise minimal.
nucleOS will be an 32-bit Operating System (perhaps we'll make it 64-bit later), written in Pascal and Assembler. It will be based on the i386 architecture and will support multi-tasking later on. Project is dead since 2006-03-19.
SD is a new operating system developed in the Pascal language (FreePascal, FPC/FPK) and NASM for IA-32. It's main purpose is to provide a fast and simple 32-bit multitasking OS. The OS must have several DOS, Windows and Linux features and maybe Win32 emu.
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.
