Making an operating system, by example

If you're learning to write an operating system, you've probably looked at some complex code and have tried to make sense of it. If you're still puzzled after your first attempt, you ought to take a look at MikeOS. It's simple code for a text-based Operating System and the goal is to keep the code readable enough for developers to learn. You can get the source code (the last release was on 15th July 2008) from the official website here: http://developer.berlios.de/projects/mikeos/
