Disk Operating System

Introduction
Hello! You found the page for learning about and building disk operating systems! Disk operating systems were the primary type of operating system between the 80's to the mid 90's. Though disk operating systems have declined and are no longer used as they were back in the day, studying and build one helps us understand some basic knowledge on how the computer actually works. This course is intended to teach you some of the functions of a computer and how to build a disk operating system hands-on. The best part about this tutorial is that there will be no cost for working with our software tools for anyone with a x86 PC!

Note: Building an operating system can take a lot of work and it can be a challenge, but don't give up! Your hard work will surely pay off when you finish.

(This page is just getting started and you can help us. You don't need a degree or certification, just be Be Bold !)
