And you can view and edit our source code, because all FreeDOS programs are distributed under the GNU General Public License or a similar open source software license.
32 bit low level Operating System
This site will be a gift to MenuetOS, a 32 bit assembly coded operating system from Finland, Russia and Hungary.
Real-time, modular, microkernel-based operating system under development for i386. The first goal is to support 32-bit DOS protected mode applications made with DJGPP as well as native applications.
DOS-C Kernel is an MS-DOS compatible kernel and the original FreeDOS kernel.
FreeOS/1 is a Free, Open Source, FreeDOS based Free and Open Source Alternative OS, with open source Microsoft Windows compatibility using HXDOSExtender KernelEx,and ReactOS source code. FreeOS/1 will include new technologies and will be easy to use
Pascal Operating System, That will translate Freedos to Pascal --OSPine written in Turbo Pascal and NASM. I think now I will make all that useful before I release. Thank for Feedback (^_^)
This is GIMI, the Graphical Interfaced Multitasking Interpreter. One of the few GUIs made in QuickBASIC featuring multitasking. This one has its own script language for making programs, damm fast SVGA modes, lots of programs, and more!
Computer Manager is the first OS that takes advantage of the DOS and Linux filesystems. It also makes doing jobs easier for everyone. Once it is complete, it will be made available to everyone!

It is not your typical Linux Loader. It wont boot you out of Windows or Dos, just so you can log on to Linux. Instead it will read the Linux Images (VMLinuz, ZImage, BZImage, initrd, linuxsys,img etc...) and it will display your Linux box in a Virtual Win
