I have added a bootable USB image here to make legacy BIOS XOSL installation easy peasy! I, johneric, was the Admin of the original XOSL project starting in 2006 after Guert Vos disappeared. After 20 years, I am back to help you understand what XOSL was and still is. It is a legendary program that changed the way many of us booted our computers for the better. It can be installed to a FAT drive (such as your Windows drive) or its own dedicated partiton. XOSL is outdated on modern hardware but still usable on many systems. This project has not been improved for over two decades and is BIOS only. I began making improvements in 2006 under the XOSL2 name before I was sidelined for two decades by corruption. Today, due to the need for an operating system loader that works on modern UEFI computers, works correctly, and has an awesome GUI with snazzy backgrounds and hundreds of cool, clickable icons I am currently developing *FOSL* (Fun Operating System Loader). I'll keep you updated here!

  • The Hybrid FreeDOS/XOSL USB image makes installation quick and simple. This has been needed for a long time! Check out the HowTo.mp4 video to watch a complete install beginning to end in less than half an hour. Nice. You're welcome!
