Upgrade to Win 2K

I just upgraded a Micron PC from ME to Windows 2K. There were three compontents that required updated drivers. The NIC, Video, and Sound. THe NIC and Video were no big deal. I found and installed the drivers for 2K without any issues. The sound is another story. The sound is integrated on the motherboard. The board is a GigaByte, GA-7DX. Neither GigaByte nor Micron list a sound driver for this board for 2K. I have installed the latest bios update for the board and still no sound.I have attempedto use some drivers for similar integrated sound cards without sucess. Thoughts, Sugestions?
