Hi Karthik!

Yes, I can recommend you Andrew S. Tanenbaum's excellent book:


I understand your problem -- code only is not enough to understand a system,
with source code comments. Exactly for this purpose we are working on these
documents: 'Understanding the FreeNOS internals' and 'FreeNOS developers


The first tells you everything needed about the theory on operating systems,
and the FreeNOS
architecture, it's components etc. The second document help you to use the
theory in practise, by
step-by-step HOWTO's, examples, screenshots and development guidelines.

Unfortunately we currently have very very little time (in fact 0) to work on
so I cannot finish the documents yet. I'll post a news item on the site soon
to inform
about the current status. I expect there to be more time available in the
next few weeks,
so we can finish 0.0.5 and complete the documentation. Meanwhile, you can
join us on #freenos
on freenode if you want :-)

Ofcourse, feel free to msg me if you have any more questions.

Kind regards,
