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

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

IMPORTANT NEWS: UPX has moved to GitHub https://upx.github.io ========================

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:

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)

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

Ranish Boot and Partitioning Tools

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.

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.

Extended Operating System Loader (XOSL) is a full-featured free boot manager with a real, easy-to-use and full-blown graphical user interface. XOSL-OW is an Open Watcom port of XOSL 1.1.5 (Dec 23, 2000) by Geurt Vos developed with Borland BC31.

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

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.

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.

Operating system project from scratch to design and implement all components from boot strapping,hardware interrupts , memory manger ,file system , etc .

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

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.

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

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.

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
