In this book, we will guide you through building your own operating system step by step. Despite the intimidating reputation of OS development, the basics are surprisingly simple. Linux, for example, started with just over 8,000 lines of code. We will cover context switching, paging, user mode, a shell, device driver, and file operations in just 1,000 lines! Debugging is the most challenging aspect, requiring new skills. We will tackle the boot process, paging, and debugging techniques together. Dive into the exciting world of OS development and download the code examples from GitHub. Happy hacking!
