Incorrect.  I personally only use Int 10h for one thing and one thing
only, and that's changing the video mode.  Once the mode is set
(usually mode 13h or a tweak thereof), I never touch the interrupt
again.  Int 10h is incredibly inefficient - you can't get any decent
hardware speed from it whatsoever.  My advice - Use it to set modes,
and do the rest manually through the VGA registers.
