An instructional operating system

About

Modern real-world operating systems are too complex to be taught to undergraduates and other instructional operating systems are not complete and usable and do not work on real hardware. By providing students with a not so complex working operating system to play with, they will be able to appreciate and understand deeper the concepts underlying an operating system.

Thus, this project aims to develop a simple yet operational instructional operating system for teaching undergraduate operating systems courses. ICS-OS is a fork of DEX-OS by Joseph Dayo.

Downloads

Latest floppy image:

Test the floppy image in qemu.

$ qemu-system-i386 -fda ics-os-floppy.img

Prerequisites

Ubuntu 22.04 and above

$ sudo apt-get update
$ sudo apt-get install -y build-essential nasm qemu-kvm tcc git gcc-multilib

Arch Linux

$ sudo pacman -Syu base-devel nasm qemu-full git

Windows (WSL)

1. Install WSL.
2. Open a Linux/Ubuntu shell and run:

$ sudo apt-get update
$ sudo apt-get install -y build-essential nasm qemu-kvm tcc git gcc-multilib

Docker

See Lab 01 for a more complete discussion of how to set up the build environment.

Build instructions

Make the floppy image then boot.

$ sudo make all
$ make run

Alternatively, you can boot the floppy image directly using qemu.

$ qemu-system-i386 -fda ics-os-floppy.img
