SimpleRealModeBootLoader

Welcome to SimpleRealModeBootLoader! This repository contains a basic 16-bit real mode bootloader written in Assembly language. It is designed for educational purposes to help you understand the core concepts of bootloaders, system programming, and the early stages of the boot process in x86 architecture.

Features

• Minimalistic bootloader that fits within the first 512 bytes of the boot sector
• Demonstrates the basics of real mode operation
• Provides a clear and well-commented Assembly source code for easy understanding
• Loads and executes a simple "Hello World" kernel

Getting Started

Prerequisites

• NASM: An assembler for the x86 architecture
• QEMU: A generic and open source machine emulator and virtualizer
• dd: A command-line utility for Unix and Unix-like operating systems

Installation

1. Clone the repository:

   https://github.com/harshithsunku/SimpleRealModeBootLoader.git
   cd SimpleRealModeBootLoader
   

2. Assemble the bootloader:

   nasm -f bin bootloader.asm -o bootloader.bin
   

3. Run the bootloader using QEMU:

   qemu-system-x86_64 -hda ./boot.bin
