This is the one I am using at the moment since I can't find another one that works and I haven't yet figured out how to edit the inf myself.
It is not true that you only install it once. If you have monitor inf drivers installed, Windows XP usually drops back to monitor plug and play drivers when installing a vid card driver. If it does this, you will have to install Reforce again. I know because I had to do it myself.
