This is the full driver for a Labway ISA sound card. Win95/98 will Identify it as a Yamaha OPL3-SA2 (OPL3-SAx). This driver will also work on soundcards manufactured under the Yamaha Label with the following chip sets YMF701, YMF711, YMF715, YMF718, YMF719. You will need to extract the exe file and it will create two folders, one labeled disk1 and a disk2. Good luck, hope it helps.
