Hello Everybody,

I've released a free book under the title "A Journey in Creating an Operating System Kernel: The 539kernel Book" which teaches the reader how to create an operating system's kernel called 539kernel. The reader will learn how to implement multitasking, paging and a filesystem through this book. 539kernel is a simple x86 32bit educational kernel which has been written especially for this book.

The book is available here: https://539kernel.com/ you can read it online or as a PDF.

Regards.

Your example bootloader code assumes CS will be 0. This is not a safe assumption and it will cause your example bootloader to fail on some hardware and some emulators (particularly older versions of QEMU).
