- I strongly suggest you use int 33h subfunction 12 to have the mouse driver
- call your code to handle the mouse events.

-
- Use subfunction 12 and draw the mouse cursor yourself. I don't know of
- any mouse drivers that know of all the various super VGA modes.
-
- Alternately you can use a graphics library that does all this for you.

- Flash Graphics from FlashTek, Inc. is one such library...
