New at OS programming - 2007/12/17 04:03
Hello all, I'm new to operating system programming, but it's something I've always wanted to learn.
What I want to do is see how small I can make a functional operating system. I've been reading about some of the earliest systems, and thinking about possibly following their lead (at the beginning, anyway).
I'm thinking, use a minimal kernel and shell, a shell that includes very few commands (to start with), and it closes the shell completely on loading a new program, and loads again it on exiting (like some DOS programs).
Obviously, I'll be wanting to run it from a floppy, and not a hard disk  .
What I want to ask is; where do I start? I'd like to write a kernel/OS, but all of the tuition pages I've seen on the 'net are either for "Hello world" OSs that do nothing, or writing systems that are way more complex than I want to write at the start. I'm a programming student at college, with a (small) experience in C and C++. I am armed with a linux box, but I'm not incredibly experienced with that either (I can use some command lines etc... and the GUI).
