I'm looking for a good tutorial on OS design. Having read a few about the theory, I'd like to find out more about the practical side of things. A step by step guide to creating a simple Operating System in C (and of course a little assembly) would be great. I've searched for many, many days, and have had no luck. If anyone knows of such an entity, your knowledge would be greeted with much appreciation.
Thankyou for your time,
