I'm not talking about the boot up ones. I'm talking about how do i program and make my own operating system
You do a lot of reading first. Try wiki.osdev.org . message edited by ijack
This, and your other question about writing your own anti-virus are rather like asking how do I build a rocket and get it into orbit. The answer is that you have to study the topic in depth and then gain practical experience. Nobody could possibly answer a question of that type on any forum. Are you just winding us up?
Always pop back and let us know the outcome - thanks
The good news is that with your own OS you won't need anti-virus software, so that's one less job to do.
