About
Koiz-OS is a project I started in 2020 to create my own operating system from scratch. It initially served as a project to help me better understand how operating systems works in general and is a bit of a pet project I do just for fun. It's not meant to be used in production settings. Below is a brief summary of my milestones with links to the full articles.
Milestone 1 - Bootloader
Highlights:
- Programmed a custom bootloader to load the operating system
