Reflective textures

I've just had to reinstall FS and didnt have the chance to backup anything on it 
on the last install someone told me how to get reflective textures to work on a GeForce 4 MX card. By default, even with checkboxes set, the card would refuse to do them. Its got somting to do with changing a line in the display.cfg
Ring any bells for anyone?
