sOS Summary

Why another Kernel? Simple, to learn and share my knowledge with others!

Story

Initially it was developed only to boot and show a simple “Hello World!”, but I wanted to go beyond and so born sOS (thanks Cere for the name and Vox for the codename :)…

The developing has started in June 2010, initially with the help of Wikipedia and OSDev and then with paper and electronic books (like OS Design and Implementation, by Tanenbaum & Woohull).
