Hi, I am new to linux. I have x86 with Redhat linux installed on that. But I want to start writing some basic kernel level code. So question is: 1) Where should I change my code. How should I compile my changes? 2) How to boot up my linux machine with new image. 3) If my new kernel image is not good enough for my machine to come up, then what is the method to tell linux machine to use some backup image incase...
