An operating system based on the best Windows NT design principles
ReactOS is an open source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft Windows NT family of operating systems (NT4, 2000, XP, 2003).
Syllable Desktop is a complete operating system that is easy to use, powerful, lightweight and extraordinarily fast and responsive. It has its own kernel, filesystem, GUI and applications. Syllable Server is a matching small and efficient Linux server.
JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.
Haiku is an open-source operating system currently in development designed from the ground up for desktop computing.
DPM explores technologies to improve power management, with a focus on techniques applicable to running systems, adjusting power parameters on-the-fly in order to save power during brief idle periods or execution of tasks with lower power demands.
dr'ex is a GPLed exokernel written in C/asm for the IA32 architecture. Simple but powerful code, low level user interface and hardware resource management at user level are the main architecture goals.
A port of the Linux kernel and tools to the iPod.
Project OctaneOS(Orange Linux) is currently a x86 Hobby operating system that is lightweight and contains standard operating system kernel modules.
Our mission is to explore and develop new operating system concepts; to redefine the architecture while using assembly language for most of the underlying architecture.
Clicker is a project for a Multitasking Open-source operating system written from scratch. based on a modular micro kernel. We want to explore new way of designing and using OSes :) [newz: PCI, NE2K and VBE]
ItaliOs è un sistema operativo totalmente in italiano.
We are currently developing our embedded TCP/IP modules, industrial ethernet systems and wireless platform for system control and data acquisition. Our main development environment is Linux and GNU tools like GCC (ASM, C, C++) and Python.
This project is aimed at getting Linux to run on the palmOne Tungsten E device. This involves making a bootloader for the PalmOS 5, building a working Kernel, and making a distribution that will fit the PDA.
Agnix is an educational, network operating system kernel. It is ideal starting point to learn about operating systems. The main goal of the project is to provide a network kernel fully compatible with the Linux Kernel in the system call layer
The DEX Operating system allows for the dynamic reconfiguration and customization of various system services using concepts found in extensible operating systems. The ultimate goal of this operating system is to achieve zero static inter-module calls.
JX is a flexible Java Operating System that can be customized for different execution environments. It provides separate protection domains for operating system components. Each protection domain may have its own execution environment.
A simple open source OS with basic functions, libraries and drivers. Compatible with x86 arquitecture, 32bits(recomended). You can easily compile it, any time, by running the compiling script included in the archive. Meant for beginner or advanced programmers on C or ASM, Nanux can help you understand the functions of the operating system, or create one by yourself. Minimal requirements: - x86 Arquitecture, PC - CPU Intel Pentium I, 200 MHz or newer, (maybe AMD, but is not recommended) - 4 MiB of RAM - CD/DVD ROM, USB or Floppy to run the ISO Image - keyboard /*Future updates are coming :) */ ==================================== For any questions or comments about the project you can write me at: - firstname.lastname@example.org - email@example.com - Facebook: Bozhidar Peychev Please rate and comment this nice OS :) Thanks for using Nanux Kernel ====================================
Real VMX is a VxWorks like operating system kernel released under LGPL. It should support multiple hardware architectures, only i386 support now. Help wanted with ports to other architectures. Development is done on Linux with the GNU gcc compiler.
SmuglyOS (Small and Ugly Operating System) is a simple os written in assembly that boots off a floppy.
An ambitious project being undertaken by the teens of the UK, accepting new members, to create a stable yet powerful OS targeted at webhosting. And our main aim is to keep it simple for the newbies out there. ;)
AtlantisOS - An operating system designed from scratch, implemented without using older code and made to be the best
Caracal Boot Loader (cboot) is a second stage boot loader which takes over from GRUB (or other multiboot compatible loader) and prepares the system for your higher-half kernel. It now also includes VESA mode setting support.
GrindarsOS - 32bit protect-mode one-task operating system.
LF OS is a little operating system written completely from scratch It supports multitasking and (later) multiuser. It is Multiboot-compliant, so it can be booted by GRUB. As Executable Format it uses ELF. At the moment, work is focused on the Kernel.
Neptune is a kernel and operating system for x86 PCs.
Neptune is a kernel and a complete operating system. The Neptune kernel can be used in any of your projects and the Neptune operating system depends on the Neptune kernel. For information on customizing Neptune, go to: http://neptuneos.eu.pn/devel.html
