Concepts you may want to Google beforehand: stack
Goal: Learn how to use the stack
The usage of the stack is important, so we'll write yet another boot sector with an example.
Remember that the bp register stores the base address (i.e. bottom) of the stack,
and sp stores the top, and that the stack grows downwards from bp (i.e. sp gets
decremented)
This lesson is quite straightforward, so jump ahead to the code.
I suggest that you try accessing in-stack memory addresses by yourself, at different points in the code, and see what happens.
