The book is over a hundred dollars.

As someone who is working on a simple os and a college student, this saddens me.

I'll have to see if my library has one.

well, it is a textbook after all. perhaps the textbook industry isn't so virulent in your neck of the woods.

@gravypod if your college library doesn't have it you should ask them if they can get it through interlibrary loan; most colleges (in the USA) participate in this program which gives you access to virtually every book ever printed.

I'll give it a go. Hopefully they do and I hope Minix has the chicken and egg problem sorted out of loading a microkernel.

Interesting article on Minix by Tanenbaum which featured on HN recently: http://cacm.acm.org/magazines/2016/3/198874-lessons-learned-...

"Operating System Concepts" (aka "the dinosaur book") by Silberschatz, Galvin and Gag is a classic. It's very approachable, compares real operating systems' design choices, and covers some theory.

It's a very biased walk-through of a bad example.

You'd do better to look at xv6. That's like v6 UNIX, minus permissions, plus SMP, running on 64-bit x86. It's very clean and modern C99.

Appreciate the recommendation. I gotta relearn a bunch of stuff due to a brain injury wiping it out. A simple x86 OS in modern C will fill in plenty of blanks. :)

Thank you for the suggestion! Happy to see that my University library actually has it.

Is that Operating Systems Design and Implementation by Tanenbaum?
