AcOS is an acronym for Assembly Constructed Operating System. As the name suggests AcOS is written in the assembly programming language and written for the Intel i386+ and compatible range of processors. Still in early development
Ace is a micro kernel for developers and researchers. The main goal is to create a very light and compact kernel from scratch with modern OS research concepts.
Achelous is attempt to clone Mac OS X for the Intel X86 Chipset. There are currently two teams working on the project: the Kernel team and the GUI team.
Acquaintance OS aims to be a lightweight Linux distribution based off of OpenSUSE. Remember, don't be fooled by the OpenSUSE branding, this project is very different from OpenSUSE, software-wise and goal-wise.
AO RTOS is small real time OS based on Active Object concurrency model
AO-RTOS is a pure object-oriented small footprint real-time operating system for embedded devices. The project is using Active Object (or Actor) concurrency model and finite state machine (FSM) design template as implementation base.
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.
AVOS is an advanced Real-Time 32-bit operating system that will work in any 80386 & above architecture pc's. AVOS employs a message passing scheme. The project has two main parts - The booting phase and kernel development. It is written in C and 8086 ASM.
Agnix is a small operating system kernel for i386, supporting 32-bit protected memory mode, paging, hardware switched tasks, memory tests, PCI bus, devices, PCI IRQ routing, RT timers and network protocols.
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
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.
The Apostle Project is a project seeking to provide a well-designed alternative to existing operating systems. The goal is to create an operating system that works - really works - because it's both appropriate and effective for the people who use it.
An open source OS written in assembly.
An open source OS. It is 32-Bit and when possible 64 and 128-Bit. We are working on a complete rewrite. After which we will work on our UI. ATTENTION!: After AquariusOS 0.0.4 AquariusOS will be based off of aqua-next. 0.0.5 with an aqua-next base will hopefully be released BEFORE 2016.
Why do it the tradidtional way when you can do it a new way? Why use an existing wheel when you can reinvent it yourself? Why do it the easy way when a hard was exists? Why? Because we are professional geeks!
this is arabic Os form scratch build by arabic Team
Soft-realtime operating system, based in a microkernel design and providing QoS and persistence capabilities.
Atomic OS is a responsive Web 2.0 operating environment & development platform. Based on AJAX techniques, it emulates/provides standard operating system features including a command-line shell, interpreter, filesystem, database access and GUI services.
Microkernel OS, based on own microkernel, able to run on PC/i386 and better.
Small real time operating system for AVR and ARM microcontrollers
AvRtos is a small, preemtive, priority based real time operating system for Atmel AVR and ARM microcontrollers. It was written in C. AvRtos provides message queues and semaphores for task synchronization. It uses a static memory allocation scheme. AvRtos is nearly the smallest RTOS out there. Even pico]OS is much bigger. AvRtos can be compiled using gcc compiler. There is a AvrStudio 4 and Eclipse project file to get the example code working very quickly.
BOS – B.lu operating System, is an operating system dedicated to small microcontrollers and CPUs without MMU. Actually is dedicated to Texas Instruments MSP430 microcontrollers (it can be ported to other CPUs without great changes)
fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface
'bglimiter' is a Perl script for monitoring and limiting of background processes. Code is mainly based on the 'bgcheck' Perl script by firstname.lastname@example.org , the script was modified so it would work on BSD's.
The BTnode is an autonomous wireless communication and computing platform based on a Bluetooth radio and a microcontroller. It serves as demonstration and implementation platform for research in mobile and ad hoc (MANETs) and distributed sensor networks
NOTE: This page and the babyos code are no longer being actively maintained. (Sorry, just no time; I have to focus on other things.) BabyOS is a simple in-memory operating system kernel for educational purposes, far from a full-fledged system. For a deta
