That book includes the MINIX source. Its quite intense though, dealing more with the implementation.

If you want to understandb the theory "Modern Operating Systems" mnay be more appropriate.

Mind you though, writing an OS is no easy task..... you will need a strong computer-science background, and many years of hard work.
