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.
