Building a simple operating system from scratch - for the x86 architecture What you'll learn:
Be able to build a simple operating system for the x86 architecture.
Understand real mode
Understand protected mode and long mode
How to handle interrupts and exceptions in the 64-bit mode
How to write OS kernel with the assembly code and C code
Be able to write print function to print characters on the screen
Be able to build a memory manager using x86 paging mechanism
How to write timer handler for the process manager
How to build a process manager to schedule processes and change them among different states (sleep, ready, killed)
How to implement system call module to make user programs running in the system
Write a keyboard driver (PS/2)
Write a simple console and interact with OS kernel using commands

Requirements
Basic Knowledge of x86 Assembly Language and C Language
A test computer and USB flash drive (If you want to run the OS on a real machine)

Description
This course is intended to teach you how to write a simple operating system from scratch. It covers basics about the x86 architecture and low-level programming. In this course, we will take you through the process of building a small working system.

Each section contains:

engaging videos

downloadable resources
