*Concepts you may want to Google beforehand: 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.
