Do you mean with the 'little book of OS dev'? Or one of the other resources?

In general, my experience has been that OS dev is a topic that is best approached through the study of a variety of different documents, simultaneously. For example, you would do well to read both the originally posted 'little book...', as well as the University of Birmingham text. Then it might be a good idea to look at the OSdev wiki pages for the specific tasks that you want to work on.

Unfortunately, there seem to be few /completed/, and high-quality texts available. It is certainly a shame that there is not a modern, high-quality book about OS development (that I know of), but the motivated student can certainly find the needed information. Good luck and have fun!
