charleX OS

charleX is a simple OS ... kernel written with c programming language and reference of this code is 'codeproject.com'. I still working to make a better kernel than this one, and many features will be added to this project. I wanna create the free and open-source OS like gnu/Linux, *BSD,... and you can support us. if you like this project, give a star to the project and send better code to us.
