Creating a Bare Bones Bootloader

This brings back memories of reading through Norton's programmer's guide to the PC, figuring out how all the various interrupts worked. It was always faster to write to b800:0000 than use int 10h (assuming a color display of course!).

Yep, instead of looping over an interrupt just use "rep movsb" between the data segment and display memory.
