Nasm OS

Barebones x86 Operating System

Overview

NasmOS is a simple demonstration of a barebones x86 operating system. It consists of a minimal bootloader and a basic kernel that displays a message, showcasing the foundational steps in OS development.

Prerequisites

• NASM: For assembling the bootloader and kernel assembly code.
• Open Watcom: Used to compile the kernel's C code. Watcom allows for low-level C programming suitable for OS development, making it easier to work with hardware and memory directly.
• QEMU: A virtual machine emulator that allows you to test your OS without needing real hardware.
