IDE & Memory Management

So I wrote a temporary memory management implementation, using the first-fit algorithm. I am planning on implementing the buddy system or possibly something newer later on. I only needed a temporary fix so I could continue.

I was able to initialize the IDE interface, but I'm having difficulties finding examples of uses of it in the disassembly. Also, the m5249 docs don't seem to have much info. Hopefully I will be able to figure this out soon so I can interface with it and then write disk io functions.
