sumeet / osdev-386

Making my own DOS for the 386 (my first computer from when I was 4)

osdev for 386

• Started out as wanting to learn operating systems, and more about the computer I used when growing up.
• Started a simpler bootloader in 386 Assembly
• Wanted to go into protected mode (32-bit mode) and get more access to features. And then I found out that MS-DOS actually didn't go into protected mode, it used the original real mode. (And as far as I understand, you were also only able to access 1MB of memory)
• Then decided to work in real mode (16-bit mode that the 386 boots up in), and use the BIOS to make an "OS". Really the first thing I want to do is make an interactive shell / REPL. So I'll be making a programming language.
• Rust makes doing this easier for me.
• It's still not for free, we're going to roll no_std and have to roll our own stuff.
