Welcome to TechSpot
You could try here (it is a Yamaha soundchip on your mobo)

Driver is for NT but will probably also work on XP

also the drivers page for your mobo at Gigabyte...

although, installing drivers in Win98 can be difficult if it chooses to be non-cooperative. It's been too long since I dealt with Win98 to get more specific about battling OS vs. Drivers issues.
