This year we have taken a project to build a kernel for a Operating System!
Any good help or suggestions :confused:

Since it's a project I'd guess you should keep it small, and not bloat it.
Perhaps work out what architecture you want to program for afterall you could potentially write a kernel for PDA's, mobilephones, small terminal systems.

In fact I found this http://neon1.net/misc/minibsd.html , it's not how to build a kernel but it was a project someone was doing to create a mini version of the freeBSD OS that could fit on one of these http://www.soekris.com/net4501.htm I'm just pointing this out for an application that could be done.

I would also suggest checking out some newsgroup on current Linux OS kernel development, like FreeBSD/OpenBSD etc. (If you don't have a newsreader, check google for their feed of newsgroups.)

Other than that, good luck with your project.

Thanks Stry!
This is for intel pc's not networking OS!

I am not sure from where should I start?
Linux is a very big thing! As you said I don't want to make it bigger :S

Then...
