Simple Operating System

This project is a minimal 16-bit Operating System written in nasm asm and C. When built, contains a bootable disk image(main.img). This project is intended for educational purposes

Requirements

• nasm – assembler for 16-bit code
• make – build system to run the Makefile to automate compilation and .img file creation in build folder
• open Watcom v2 - a C compiler with 16-bit support, which can compile C code and link it with assembly files.
• other packages may be needed, make sure to run make install_tools (for Ubuntu/Debian systems) before building
• Optional: qemu-system-i386 – emulator to test the bootloader on

On Ubuntu/Debian-based systems, you can install the required tools with:

sudo apt install build-essential nasm make

Build

This project uses make to create the build folder and build the files into that folder. Simply run:

make install_tools

install_tools will install all the required packages for this project (on ubuntu/debian systems). Then run:

make

Additionally, to clean the build folder, run:

make clean
