Project Introduction

Summary

This project provides a step-by-step tutorial and accompanying code to walk you through the process of creating a minimal operating system kernel capable of running basic processes. It covers essential concepts from boot loaders to memory management.

Problem Solved

Learning the fundamentals of how an operating system works requires delving into low-level concepts often abstracted away by modern languages and frameworks. This project demystifies OS creation, providing practical experience rather than just theoretical knowledge.

Core Features

Step-by-Step Guide

Detailed explanations covering boot process, protected mode, memory management, and basic process handling.

Modular Code Examples

Cleanly separated code for each chapter, allowing users to build the OS incrementally and understand individual components.

Tech Stack

Assembly (NASM)
C
Linker Scripts
QEMU (Emulator)
Makefiles
