Can't it's either graphic or text, not both. They are different memory
locations on the video card.

A long long time ago, in a land no one ever ventures into these days,
there was such a beast. Top half graphics, bottom half text. I believe
the name they gave it was Apple II.

Then, in the early DOS days, I remember writting graphic programs (in
BASIC) that used the "normal" print command to put text on the graphic
screen.  It was slow because BASIC (or something else) had to draw
each character as a graphic. (Same as you've done with the large BGI
font, only automagically.)

I very much doubt that. They probably drew "text-looking" thingies on
the graphic screen, which is what you should do if you really want a
"mixed mode" display.

One other, very complicated method, is to design a font and use BIOS
calls to load your font, then you would use multiple characters to
build each letter (like a large LCD display).
