Real-time frameworks/RTOS based on active objects & state machines
Real-time frameworks/RTOS for building responsive and modular real-time embedded software as systems of active objects (concurrent state machines). The QP family consists of QP/C, QP/C++, and QP-nano frameworks, which are all strictly quality controlled, superbly documented, and commercially licensable. The behavior of active objects (a.k.a. actors) is specified in QP by means of hierarchical state machines (UML statecharts). The frameworks support manual coding of UML state machines in C or C++ as well as automatic code generation by means of the free QM modeling tool. All QP frameworks can run on bare-metal MCUs, completely replacing a traditional RTOS. Ports and ready-to-use examples are provided for major embedded CPUs, such as ARM Cortex-M, ARM7/9, MSP430, as well as Arduino and mbed. QP/C and QP/C++ can also work with a traditional RTOS/OS, such as ThreadX, FreeRTOS, embOS, and uC/OS-II as well as Linux (POSIX), Windows.
ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.
Run Linux on Windows or other OSes, natively.
Cooperative Linux is the first method for optimally running Linux on Windows and other operating systems natively. It is a port of the Linux kernel and support code that allows it to run cooperatively without emulation along with another operating system.
LuninuxOS is a Debian/Ubuntu based Linux distribution.
LuninuxOS is a Debian/Ubuntu based Linux distribution designed to be beautiful, clean, simply, fast, and stable. it was previously known as Sn0wl1nuX. It is super-fast, great-looking, secure, intuitive operating system that powers desktops and laptops. LuninuxOS is absolutely free, and comes with a selection of the best applications designed to meet most of your daily needs. It can be run directly from a CD/DVD/USBStick and optionally be installed to a HDD, including IDE, SCSI, SATA, PATA and USB drives.

Tool kit for building highly secure special-purpose operating systems
The Genode OS Framework is a tool kit for building highly secure special-purpose operating systems. It scales from embedded systems with as little as 4 MB of memory to highly dynamic general-purpose workloads. Genode is based on a recursive system structure. Each program runs in a dedicated sandbox and gets granted only those access rights and resources that are needed for its specific purpose. Programs can create and manage sub-sandboxes out of their own resources, thereby forming hierarchies where policies can be applied at each level. The framework provides mechanisms to let programs communicate with each other and trade their resources, but only in strictly-defined manners. Thanks to this rigid regime, the attack surface of security-critical functions can be reduced by orders of magnitude compared to contemporary operating systems.
nxtOSEK is an RTOS for LEGO Mindstorms NXT. nxtOSEK consists of I/O driver part of LEJOS NXJ, TOPPERS/ATK1 RTOS, and glue code for them. You can write applications for NXT in ANSI-C/C++. Check nxtOSEK site: http://lejos-osek.sourceforge.net
7-max increases the performance of some applications up to 10-20%. Windows uses small (4 KB) RAM pages by default. 7-max allows to use large (2/4 MB) RAM pages.
Committed to the development of fundamental ACPI (Advanced Configuration and Power Interface) components for Linux. This includes a generic ACPI table parser, AML interpreter, bus and device drivers, policy, user interface, and support tools.
Haiku is an open-source operating system currently in development designed from the ground up for desktop computing.

"µOS++" (micro OS plus plus) is an open source, royalty-free, real-time operating system intended for embedded systems built around ARM Cortex M or AVR devices. It is based on a preemptive scheduler written in C++ (more info in the Wiki).
scmRTOS is tiny Real-Time Preemptive Operating System intended for use with Single-Chip Microcontrollers. scmRTOS is capable to run on small uCs with as little amount of RAM as 512 bytes. The RTOS is written on C++ and supports various platforms.
Fast, multi-threaded OS for PCs and 386+ based embedded systems. Runs many DOS, DPMI and Win32 console programs. 100% assembly with segment protection.
The WRT54GL Tarifa enhanced firmware. Linksys WRT54G/WRT54GS models V1 to V4 and the WRT54GL V1.x This Third Party Firmware is functionaly the same as the original, the improvements are to make this router more scaleable, by increasing the capacity.
Real-time, modular, microkernel-based operating system under development for i386. The first goal is to support 32-bit DOS protected mode applications made with DJGPP as well as native applications.
An easy to use Development Environment for OS developers to design, write, compile, test, and publish new or existing OS projects with ease.
RMF-DOS is a project to create a compact, 8086-compatible, free clone of MS-DOS.
Eclipse OS is a C++ kernel that I am starting as a summer project. Right now it is fully bootable and can accept input from the keyboard. It can also do simple tasks like detect how much RAM a computer has, or tell time. I am hoping to port C++ compiler.
Jinx is a minimalistic graphical operating system for use on old computers with 64MB RAM. Suitable for desktop,business,library use. Includes browser, office applications in 50MB ISO. Optimized for tiny size.
BrickOS is an alternative software environment for the LEGO(r) Mindstorms Robotic Invention System. The intent is to allow developers to write C and/or C++ code for the RIS platform.
With this project I intend to write a really, really simple OS, just for fun and learning. I think I will never have a really usable version, as I said, that's no my objective.
