My VGA card has some  non-standard text modes -
60x80, 60x100, and 75x100 to name but a few.

I would like to use them under Minix and possibly under Esix, too.

Is it possible via a suitable set of IN's get the whole
VGA state (not including the actual graphic image or text part)
and by OUT'ing them in some proper order achieve the same
screen mode ?

If yes, has anybody code to grab the VGA state ?

If not, or if no one has code for it, or anyway,
what is the best book about VGA register level programming ?

I wouldn't like to walk the VGA Bios code, and haven't
even any book or reference material about VGA yet.
