Want to write a Operation System

To most of the computer science students, operation systems are the most mystical pieces of software. I was quite curious about how a software can bootstrap itself from nothing back in my school time.  So, you may have a good reason to try this website: OSDev:

"This website provides information about the creation of operating systems and serves as a community for those people interested in OS creation. The wiki contain articles about various OS developing subjects.  "

It basically provides all the details you need to build your own operation system. I mean, if you would like to spend a semester in studying stuff listed in this site, you probably can learn much more than listening boring producer-consumer, semaphore stuff.
