Hi
I am wanting to write a very simple OS. I have learned something about the basic concepts of OS in my OS class, but have no idea how to start and which are the requirements.
I know C/C++ good and little Java.
Can anybody point me how to start writting the simplest possible OS, cause It looks like a fun thing to do once you know what u're doing.
I have heard about linux from scratch, but i dont want just another linux, i want to learn from the very basic.
Any tutorials or books?
thanks
