<commit_before>How to Make a Computer Operating System
=======================================

**Caution**: This repository is a remake of my old course. It was written several years ago [as one of my first projects when I was in High School](https://github.com/SamyPesse/devos) so it's normal if some parts of the code looks like "crap". The original course was in french and I'm not a english native.

**Source Code**: All the system source code will be stored in the **src** directory. Each steps of the course will be linked to a git tag.

### What kind of OS are we building?

The goal is to build a very simple UNIX-based operating system in C++, but the goal is not to build just a "proof-of-concept". The OS sould be able to boot, start an userland shell and be extensible.

### Summary

#### [Chapter 1: Introduction about x86 architecture and about our OS](Chapter-1/README.md)

#### Chapter 2: Setup the development environment

#### Chapter 3: First boot with GRUB

#### Chapter 4: Backbone of the OS and C++ runtime

#### Chapter 5: Base classes for managing x86 architecture

#### Chapter 6: GDT and IDT

#### Chapter 7: Memory management: physical and virtual

#### Chapter 8: Process management and multitasking

#### Chapter 9: External program execution: ELF files

#### Chapter 10: Userland and syscalls

#### Chapter 11: Modular drivers

#### Chapter 12: Some basics drivers: console, keyboard
