DelOS

DelOS is a tiny 32-bit educational x86 operating system designed for learning OS development fundamentals.

Requirements

• nasm - Netwide Assembler
• i386-elf-gcc (32-bit cross-compiler)
• qemu-system-i386 - x86 emulator
• make - Build automation

Installation

Ubuntu/Debian

sudo apt install nasm qemu-system-x86 build-essential

For the i386-elf cross-compiler toolchain, you'll need to build it from source or use a pre-built package.

See OSDev Wiki for detailed instructions.

macOS

You are free to use a container / virtual machine for compiling the project. <3

Quick Start

make       # Build the bootsector + OS image into build/delos.bin
make run   # Launch QEMU with the image
make clean # Clean build artifacts

Note

This is an educational operating system. Do not run on bare metal hardware you care about.

• Tested in QEMU only. Behavior on other emulators or real hardware may differ
• No warranty or guarantees of any kind
• Use at your own risk :)
