no kidding...its so hard to figure out vesa's docs if you haven't really
programmed in Protected mode.... I am also having trouble doing this... I know
that you need to call the function and have it return a struct of info into a 255
byte buffer at es:di but.. how do i get es:di to point to the struct...i have no
clue...And then there's the matter of getting the linear frame buffer's
address...
