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.
The objective of the TPM Emulator project is the implementation of a software-based TPM and MTM emulator as well as of an appropriate TCG Device Driver Library (TDDL).

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.
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.
QNAP GPL Source
GPL source for QNAP Turbo NAS
Open Source Linux driver for wireless network cards (DWL-[G]520+ PCI, DWL-[G]650+ CardBus, GL-2422MP mini-PCI, DWL-120+ USB etc.) which use the entirely undocumented Texas Instruments (TI) ACX100/ACX111 chips, for 2.4.x , 2.6.x to 3.x kernels. FreeBSD: see some other website (FIXME URL got clipped). !! BIG FAT NOTE: development (i.e., driver "releases") is happening in git source repository tree (as of 2011-09-04), thus you're expected to look there (see web site menu Code --> Git) !!
OS9exec - execution environment for OS-9/68k user-mode programs on MacOS9 / MacOSX / Windows and Linux host OS. (OS-9 is an RTOS of Microware/Radisys)
Nucleus is an Operating system Kernel that is totally different from Linux and Windows. It is easy to understand and implement. It will have native support, small architecture and full VGA support (no text mode).
nf-HiPAC is a high performance packet filter for Linux. It provides the same rich feature set as iptables but uses an advanced algorithm to minimize the number of memory lookups per packet.
The Linux abi is a patch to the linux kernel that allows a linux system to run foreign binaries. For further details please see the project homepage.
Fireball (FSD) Amoeba is a distributed operating system. It collects a huge varity of single machines connected over a (fast) network to one, huge computer.It's a full Operating System Distribution. Based on Amoeba,Vrije Universiteit.
Alternative operating system for x86 computers
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
Open source realtime multitasking system for C16x and derivatives (C167, XC167, ST10, etc.), focussed on minimum resource usage.
The WOLKs are stable and development kernels, containing many useful patches from many projects. Goal: Stability, Scalability, Performance and most important: Security.
An operating system written in C & assembly.
An operating system written in C & assembly. FruityOrange uses the concept of a monolithic kernel and GRUB as bootloader for the kernel and some modules. There is still no release. If you want do try the development-version, get the Sourcecode and build by yourself!
The project discusses an architecture, prototype implementation and test tools for wireless scheduling using currently available hardware (e.g. 802.11 WLAN). It is based on a patch/new scheduler for the Linux 2.4.X kernels and extensions for the tc tools.
it is used to fetch several System V IPC message queue infos, which ordinary implementation of ipcs didn\'t provide, e.g. scanning the system for active queues or. also, it comes with a tool to creat/destroy message queues and send messages over them.
A new advanced customizable graphic menu multi boot and OS loader based on XOSL project with gujin project features, this project integrate too a mini OS to provide certain customizable specialized maintenance tasks before boot partition/load OS target.
The goal of the Basic Operating System (BOS) project is to write a new modular and fast operating system in NASM and GCC.
