I'm trying to learn how video memory is arranged for various screen
modes on an IBM VGA card.
Currently, I know how to write to memory on the first page, but
accessing other pages and flipping between them is something I can't
figure out so far.

Could somebody point me in the right direction and give me titles of
complete and comprehensive references?

Thanks in advance,

P.S. I know that writing directly to the screen is evil, but this is
strictly for curiosity that I want to learn how it's done.
