A Trivial Operating System for 8051 (ATOS51). ATOS51 is a trivial operating system for 8051 microcontroller. As its name, it provides only multitasking feature.
AWOS: The Universal Operating System.
Embedded Real-Time Operating System (RTOS)
Akalon is a Bare-Bones Embedded RTOS that's designed to be simple and portable to any Microprocessor or System (Board). Currently supports the Intel and ARM Architectures.
Hobbyist operating system using a new microkernel. The objective is to not get bogged down by ancient legacy processor support. The OS is meant to be designed from the ground up, without utilizing any legacy or existing implementations or designs.
A Debug style tool for OS Free systems
BootDebug is kind of an odd ball tool. It boots up like an OS (using Grub) but is not really an OS at all. What it provides is a tool to look at the system in a very pure state, allowing you to see exactly what is going on at they very start of the system powering up.
C-BIOS is an open source BIOS for MSX computers.
C-BIOS is an open source BIOS for MSX computers. C-BIOS can be shipped with MSX emulators so they are usable out-of-the-box. This project aims to improve C-BIOS by fixing incompatibilities with the MSX BIOS and the development of a Disk ROM.
COBE is a operating system, wich is right in developing. Stay tuned.
We want to utilize idle memory located on Internet or WAN to improvement file system performance. It's something like cooperative caching.
DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series. These operating systems belong in the same class as Linux in that they are based on UNIX ideals and APIs. DragonFly is a fork in the pa
A special-purpose 4.4BSD-based UNIX-like operating system, designed for machine control applications. Using low-cost hardware, FabBSD can be used to control a wide array of CNC milling machines, lathes, routers, process-control and automation equipment.
GaryOS is an entire GNU/Linux system in a single bootable file
GaryOS is an entire GNU/Linux system in a single bootable file. While most boot/rescue systems use an ISO with SquashFS, GaryOS is a single binary file consisting of a Linux kernel and a Funtoo/Gentoo initramfs. The file is generated using a customized Funtoo/Gentoo configuration with a default Grml Linux kernel configuration via the Metro automated build tool. There are currently no major projects which take this same approach on this scale. The result is a smaller boot/rescue file that is just as comprehensive, yet easier to deploy and manage. GaryOS enables you to drop a single file on any media, point a bootloader at it and go. Upgrades are as simple as replacing the file and/or adding another bootloader entry. Rescue media is more likely to be available and up-to-date if it is convenient to deploy and manage, which is one of the primary aims of GaryOS.
Gebix is a FreeBSD-based operating system that will be available for both x86 and ARM as of version 0.7 Release Candidate 1. It will sacrifice most of the legacy support to transition to new or recent alternatives.
Knose OS is a portable clone of Palm OS targetting the ARM, 68K and x86 architectures. Binary and source compatability with Palm OS 5 will be strived for whever possible while still moving the operating system forward with features like multi-tasking.
The first true nanokernel for x86 that gives a unix prompt on a real bourne shell in respect of all security rules!
A FOSS operating system that aims to meet NSA's TPEP TCB A1 evaluation standard while retaining application compatibility at minimal performance overhead.
MOS, the MANTIS Operating System, is a multi-threaded OS designed for resource-constrained sensor platforms. A simple C API enables MOS to provide simplified programming of wireless sensor nodes. MOS Supports TelosB, Mica2/Dot, and MicaZ motes.
Rewrite Minix 3 from C to D
The idea is to rewrite a good part of the Minix 3 OS from C to D, hopefully making the code easier to understand by grouping code in modules. Minix 3 web site: http://minix3.org/ D programming language: http://www.digitalmars.com/d/
MinopsOS is a tiny operating system for PC computers.
MinopsOS is a tiny operating system for PC computers. It's small enough to fit inside the boot sector of a floppy disk.
NandOS ist ein Betriebsystem.
Operating System in 512bytes.
A small operating system in only 512 bytes.
OnyxOS is a 32 bit protected mode operating written primarily in C with a small amount of ASM. It aims to be a small OS useful for learning low-level OS development and provides a base for other hobby OSes to grow from. It features a shell called Slosh.
Custom firmware and IDE for the VEX Cortex Microcontroller
This project has been moved to http://pros.cs.purdue.edu/ PROS is a lightweight and fast alternative operating system for the VEX Cortex Microcontroller. It features multitasking, low-level control, and Wiring compatible functions to harness the full power of the Cortex. With a real-time kernel based on FreeRTOS and a development environment built on Eclipse CDT, PROS uses proven software to increase the reliability and usability of the VEX development system across all three major computing platforms. PROS is currently under active development to make it usable for VEX high school and middle school teams. PROS is intended for advanced VEX users seeking to move beyond competing environments. Eclipse and FreeRTOS have their own licensing agreements. Please see http://www.eclipse.org/legal/epl-v10.html and http://www.freertos.org/a00114.html for details.
