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:

UEFI fdisk is a port to UEFI of the famous fdisk partitioning tool from util-linux, see https://github.com/karelzak/util-linux . Now since this program runs directly under UEFI shell you don't need to *boot* the system to edit partition tables.

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

To boot and run your experimental assembly language programs, booting them with either a USB Memory Stick or a DVD. This is Not for Linux. Program only tested on Windows 7 Laptop. The Memory Sticks have to be formatted FAT 32 with a Volume Label = "FINDING" ). The memory stick should have 1 single Fat32 partition It must be of very low capacity, of 128 Meg bytes maximum? Because the memory stick must Not have a MBR system. Copy your own experimental program to the empty memory stick as a file. Log off, turn off the computer, turn back on, press a number and your program should be able to run with computer booting and in "Real mode".. Booting-Aids_2_ can do several things which have a definite educational value, because booting lets your own programs run without an operating system until they can become like a small operating system of their own. Your programs have to be marked with the number 9090h at their exact start. It can be written like this: dw 9090h

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).

mbldr is a boot loader which fits into first sector of an HDD (MBR). It allows to choose which partition to boot and is intended to replace an MBR coming with DOS/Windows (fdisk /mbr). It may boot OSes above 1024cyl, Linux/BSD are also supported.

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).

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.

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.
