    Ancient Linux on Windows

    Ancient Linux on Windows

    Building and running ancient Linux on Windows

    While I may have started with Linux 0.11, I've expanded this to include several older relases of the Linux kernel that you can cross compile from Windows, and run on Qemu. I've managed to get the older versions of the software tools running on Windows, so that there is no major invasive source changes, outside of either broken drivers, or massaging the makefiles to find things in the new paths, and calling the appropriate tools where needed. Linux 0.10 is the first oldest version of Linux that is somewhat usable. While it lacks things like TCP/IP, and robust filesystems, it does offer a small kernel size, perfect for playing around with. You can comfortably make changes on Windows, re-compile and test all from a 'normal' desktop.
