Puzzle OS
Protected mode multitasking operating system for IA-32 processors.
How to run?
Use puzzleOS.iso to boot as VM or from CD. The kernel is multiboot compatible, so grub should recognize it.
How to build?
There are some make files and Xcode projects, but no instructions will be provided at this time.
Any docs?
No. This code is absolutely self-documented (especially it's asm part =)
If you're interested – create an issue – I'll provide some description here.
License?
Yes. MIT. Be free to use it and ask me any question.
