ATI drivers for NT

I have a Gateway G6-333c on which I just recently installed NT. I'm looking for a driver for a Chromatic Research chipset. The Windows 98 driver is called m2gfx.drv if that helps. I don't know much else about it except the Gateway part number.

(Gateway is not very helpful if you tell them you're using NT. They kind of get this far-away tone to their voice and they stop answering questions.)

Thanks,
Shawn
