Open Source Assembly Boot Software for Windows

GRUB for DOS is the dos extension of GRUB. It enables dos users to run the configuration console directly in real mode. The project also contains an utility called WINGRUB, an GUI intends to help configuring and installing GRUB in the WINDOWS environment

Project has moved to https://github.com/CloverHackyColor/CloverBootloader.

GAG is a graphical boot manager, designed to be easy-to-use and intuitive, but without loosing advanced features, like passwords or swapping drives.

XOSL is a graphical boot manager that supports multi-booting of various operating systems. Development is currently done under the XOSL2 title. Historical version download below:

AiR-Boot is a x86 boot-loader that resides completely in track 0 of the harddrive. It‘s also independent of any OS, features a BIOS-like built-in setup, is localized to German, Dutch, French, Italian, Russian (including Cyrillic) and Swedish.

Ranish Boot and Partitioning Tools

Multi Boot Manager allow chang the boot, this version need be insert into MASTER BOOT RECORD (MBR, track 0, side 0, sector 0), and the original content need be insert into last sector (Sector B3F or Physical address Track 4f, Side 1, Sector 12h). Made in

The netboot project allows booting a diskless PC over a TCP/IP based network using standard protocols like BOOTP, DHCP and TFTP. It is able to boot Linux, FreeBSD, multiple DOS variants (including MS-DOS, PC-DOS, PTS-DOS, OpenDOS, NovellDOS, FreeDOS)

Sets out to be an innovative new operating system while retaining compatibility with POSIX and Win32

ARMboot is an Open-Source firmware suite for ARM based platforms. ARMboot is heavily based on the sister-project PPCboot, which provides similar functionality on PowerPC based systems. ARMboot shall be a common, easy-to-use and easy-to-port boot 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.

The FDOS Operaing System is 100% written in Assembler (NASM). It supports FAT 12, TSR and a small Multi Kernel System. The source is very good documentated (only in English). A German, russian and English Documentation (about 40 pages) are included.

Blob is a boot loader for SA11x0 (StrongARM) platforms. Blob is able to boot a Linux kernel stored in flash or RAM and provide that kernel with a ramdisk (again from flash or RAM).

Boot loader and FLASH burner for the Motorola 68360 processor (aka Power QUICC). Based on CoLILO linux loader for Motorola Coldfire processors, however this boot loader is OS independent. Supports systems with multiple FLASH devices, runs from RAM for f

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

BIOS for Samsung S3C4510B based boards. You can use it to setup CPU/ROM/SDRAM/EXTIO, manage and burn flash, load OS kernel and pass arguments to OS kernel (now only uClinux).

fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface

The Banana Kernel is an open-source pedagogical operating system intended to provide useful means for teaching basic OS concepts, with the possibility of interaction with external modules developed by the teacher or student.

Cloudium OS is being written in pure ASM. It's designed for speed and ease, having cloud computing in mind. It also is secure (without requiring constant user input like Windows). But, how are we going to do this? Well every os wants/says these kind of things, so to accomplish our goals we follow these simple rules: keep it simple (that's way better then these complex interfaces etc. almost nobody wants), generalize (this makes things easier and more useful without extra complexity) and be inventive (sometimes doing it the classical way just doesn't work). Note: development peace will be temporarily lowered until February the fifth. Please check out our OS and Project site!

THIS PROJECT IS INACTIVE!!

A Unix-like (Not compleatly Unix-compatible) Kernel. Right now, we have (very limited support) of 80486+ IBM-PC AT compatibles. Written in C, and assembly. No network support planned for the forseeable future.

Minerva's primary goal is security. To allow all users to feel safe and secure but have the freedom to do what ever they want. We also want a fast easy way to bring every linux and windows o/s together.

Nemesis is a tiny real time operating system kernel based on x86 PCs. Its main purpose is to serve as a simple but realistic example of an real time OS kernel running on real hardware..the purpose of this is that it can be embedded in small devices lik

NewOS - Yet another operating system.

POSYS: Programmers Operating SYStem. A small, fast, dynamic, secure OS project. (In development) Language: NASM + CC386.
