Creating an Operating System: Difference between revisions

It is very useful for a multithreaded kernel to have built-in debugging facilities early on. You could have a magic key that stops the entire kernel and dumps the user to a mini-kernel with a command line interface for debugging.

=== User Interface ===

You will certainly need to impress the operating systems development community with your flashy graphics and usable user-interface.

=== Networking ===
