## What it is
A collection of study notes and accompanying source code for the Chinese book 'The Design and Implementation of a 64-bit Operating System'. It walks through building a 64-bit OS from scratch, covering bootloader, kernel, memory management, interrupts, and system calls.

## Use cases
- learn how to write a 64-bit operating system from scratch
- study bootloader and kernel boot process with runnable examples
- understand x86-64 protected mode and IA-32e mode
- learn SLAB memory pool and page table implementation
- follow along with an OS development book with annotated source code

## When to choose
- you are reading the book and want organized, commented, runnable code per chapter
- you want a structured tutorial path for hobby OS development on x86-64
- you prefer notes with one-click run scripts for each experiment

## When to avoid
- you need a production-ready or maintained operating system kernel
- you want an English-language resource
- you need support for ARM or non-x86 architectures

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: operating-systems, tutorials, education
- platform: cli
- tags: operating-system, 64-bit, bootloader, kernel, x86-64, book-notes, assembly, study-notes, linux
