Well I'm working in Protected Mode with Memory Protection so I want to have a good solid memory manager (physical and virtual) so I can give my application thier own virtual memory then have a file system / executable format before even thinking about running programs.

I actually started working on it last night and got experimental things done like the GDT and IDT and finished up
an exception handler before school.

I'm reading the intel docs and wrapping up my IRQ code before I start to implement my low level paging code so I can build a virtual mm on top of that.
