  Bootstrap yourself to write an OS from scratch. A book for self-learner.

(Here is the link - didn't quite get the image/link combo right in the original post!). I'm writing a series of posts about coding your own operating system. After reading Operating Systems: From 0 to 1 I found that some of the code does not work, so this first post walks you through writing a bootloader similar to that of chapter 7. It also adds some context that I would have found useful when I originally read the book, such as how 16-bit real mode works and some assembly programming information. I'm hoping to take a different approach to posts in the series by borrowing pieces of other operating systems and discussing how they are implemented in an effort to keep things simple and focus on fundamentals (even Linus started out with a detailed reading of MINIX).
