This is the disk that came with the card. I've used this driver in Win2K and Win2K server. It also "appears" to have the drivers for NT, 98, 95, & 3.11, but I have never needed to check. I misplaced this disk and tried to download it from here, but could not find it for WIN2K. Now, next time I misplace it, I'll be able to download it here.
