Projects

Kolibri OS

KolibriOS is an open source operating system with a monolithic preemptive, real-time kernel, video drivers, for 32-bit x86 architecture computers, developed and maintained by The KolibriOS Project Team. KolibriOS is a fork of MenuetOS, written entirely in assembly language.

ChibiOS/RT embedded RTOS

ChibiOS/RT is a compact and fast RTOS designed for embedded applications. It offers threads, mutexes, semaphores, messages, events, timers, flexible I/O with timeout capability. ARM7, Cortex-M3, AVR, MSP430 and x86 are currently supported.

ScorchOS

ScorchOS (formerly ApolloOS) is a 32-bit pmode kernel written in C and assembler.

DeforaOS

DeforaOS is a multi-purpose Operating System, providing an ubiquitous, secure and transparent access to user resources. It features a POSIX-compliant environment, and can work on top of existing systems (Linux, *BSD...). Its desktop environment is focused on usability, coherence and integration ... [More] , with many applications available already. Developed with simplicity and efficiency in mind, it suits modern embedded platforms as well. [Less]

Atomthreads

Free RTOS. Lightweight, portable, open source scheduler for embedded systems.

Brainix

Brainix is a microkernel-based, Unix-like operating system. It includes support for virtual memory, preemptive multitasking, asynchronous message passing, and the ext2 file system. It was written from scratch and runs on IA-32 (x86) computers. Brainix was inspired by (but shares no code with) ... [More] Minix. Brainix boots, initializes its sub-systems, then passes messages. It isn't mature enough to support a shell, but its developers are active. [Less]

LSE/OS

The first true nanokernel for x86 that gives a unix prompt on a real bourne shell in respect of all security rules!

hackref-os

An operating system that was built from scratch for the express purpose of having a system dedicated specifically for hacking and pentesting. The tools included were all built from scratch. There is no fancy GUI, only a command line which allows the user to finish the job at a quick and efficient speed.

csharp-os

There are many operating systems in this century. But almost any one is build by a native language such as C, C++, assembly. And there is a new effort to make a operating system in java( a JNode Project ). Then it' time to make a operating system with C#. This OS's objective is not making a ... [More] unix clone but making a Full 3D-GUI-supported and SMP and multi-platform OS. First time, a bootloader is executed in the bare-metal on the machine, and instruction translator loaded. Instruction translator translates a .NET IL code to machine instruction and loading them in the memory, then executed. This OS could open a new trend in OS Development World. [Less]

myos-32bit

This is my Hobby OS project. You may use it for educational purpose. This OS kernel is written using gcc-4.1.2 under linux. I used fedora-8, But i think it will be compilable under other linux too. The total OS is developed under QEMU for linux. Tested under BOCHS. and very little tested under Real ... [More] hardware. The source code has some inline GCC assembly and some NASM assembler files. for compilation a shell script is used. To test this you will need a GRUB floppy and in grub.conf put the kernel path. In case of any problem please contact me. ashokdotsdotdasatgmail.com [Less]
