No driver nor DirectX can alter bios of a card by itself. It needs spesific
tools provided by card's manufacturer, not Ati in case of oem cards.
So that's out of question.
I do think there are some driver files left over the system from newer
drivers. Uninstall cat4,5 , run Drivercleaner, re-boot, now install whatever
version you want. This was there will be no more files with newer version
from new catalyst.
As for water, I think you are looking at pixel and vertex shaders.
