Nice. Way back in the day, maybe 20-25 years ago, I had a first look at the boot process and wish I'd had something similar to the first chapter then. Man, it was hard to find information and ones you did you realized understanding it meant learning an entirely new subject.<p>Those were the days really. Barely having started my English studies I went looking for a single piece of information and found so much else on the way.. The tinkering and nights of frustration gave insights and a feeling of accomplishment that set me on the path to the profession I have today.<p>Then I started high school and someone showed me a shaded and textured cube they had rotating on their screen and I found out what math is good for :)
