Open Source Operating System Kernels

Super GRUB2 Disk helps you to boot into most any Operating System (OS) even if you cannot boot into it by normal means.

EmuTOS is a TOS compatible operating system for Atari ST series computers, and more. It is made from Digital Research's GPLed original sources and is a free and open source alternative to Atari proprietary ROMs.

The AROS Research Operating System is an effort to implement an Open Source and portable operating system that is compatible with AmigaOS(TM). Originally, it was meant as a direct reimplementation, but already has features not existing in AmigaOS.

xinco [eXtensibe INformation COre] is a powerful Web-Service based Information and Document Management System (DMS) for files, text, URLs and contacts, featuring ACLs, versioning, full text search, an FTP-like client (easy install, J2EE+MySQL/PostgreSQL)

The first decentralized, artificially intelligent, MEAN.js stack, operating system. Mean OS is the only operating system hosted anonymous using a P2P network and a suite of non-standard in-browser delivery mechanisms. Mean OS is specifically designed to support both Brave and Tor but is compatible with all other major browsers. Mean OS is Proud to be a BRAVE and TOR supporter, be free!!

TORO is demonstrating an innovative operating system by integrating at the same ring level both kernel and the user application server. The threads of the user application server are distributed evenly on all CPUs and running independently in parallel. The memory model chosen is NUMA without pagination. During the initialization, the memory is divided proportionally for each processor installed on the system. When a thread needs memory, the memory allocator returns a free block of memory depending on which CPU the thread is running. In the same way, TORO can dedicate resources to specific processor, i.e. a FileSystem. This only CPU then can access to this instance of FileSystem. The scheduler is based on the cooperative threading model, therefore due to this design, TORO can migrate threads between CPUs and send messages between threads without using any lock instruction. TORO is well suited for integrated system to run at high pace application servers like web servers.

Sensa is not an operating system, is a work environment compatible with Android © 4.4.4, Firefox OS ©, Linux Ubuntu 12.12 ©, MacOS Classic 7 ©, MS -DOS © operating systems, and Microsoft Windows 8.1 ©; whose distribution is free, and with source code available under GNU GPL 2.0 license .

Cloudium OS is being written in pure ASM. It's designed for speed and ease, having cloud computing in mind. It also is secure (without requiring constant user input like Windows). But, how are we going to do this? Well every os wants/says these kind of things, so to accomplish our goals we follow these simple rules: keep it simple (that's way better then these complex interfaces etc. almost nobody wants), generalize (this makes things easier and more useful without extra complexity) and be inventive (sometimes doing it the classical way just doesn't work). Note: development peace will be temporarily lowered until February the fifth. Please check out our OS and Project site!

Visopsys is an alternative operating system for PC compatible computers. In development since 1997, this system is small, fast, and open source. It features a simple but functional graphical interface, pre-emptive multitasking, and virtual memory. Though it attempts to be compatible in a number of ways, Visopsys is not a clone of any other operating system. You can demo the distribution from a “live” CD/DVD or floppy disk

A linux from windows installer, that is, an installer that runs on Windows and installs linux.

This proyect will be many things. It will be not only a software program; but also your assistant and maybe your friend. You should be able to speak with her, ask her for advice, or ask her to do your homework.It will be a powerful OS such as Linux but fr

Estaño is a mini real-time operating system (RTOS) for microcontroller. Features: Fully preemptive multitasking, Low interrupt latency, Fast and constant context switching, semaphores, r/w semaphores, mailboxs, fifos, periodic and one-shot timers

The FDOS Operaing System is 100% written in Assembler (NASM). It supports FAT 12, TSR and a small Multi Kernel System. The source is very good documentated (only in English). A German, russian and English Documentation (about 40 pages) are included.

MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler

Open Source microkernel for ia32 architecture. Basically this is a full functional operating system implementation using GNU C and nasm. Fully commented in spanish and with external documents explaining system calls, library functions, design, etc.

Minerva's primary goal is security. To allow all users to feel safe and secure but have the freedom to do what ever they want. We also want a fast easy way to bring every linux and windows o/s together.

The Patagonia OS is intended to work with x86 computers. It is for general purposes and can be modified easily and add drivers for other devices. The main idea of this kernel is transform PCs into research machines.

Graphical OS Kernel compiled with gcc 4.6.1 and nasm 2.09.08

The aim of our project is to create a portable microkernel and a set of OS services that allow good local performance, multiple concurrent operative system personalities (ie UNIX and a native interface) and easy integration of distributed components.
