This is for an Ensoniq Soundscape sound card. The big Ensoniq chip says OPUS WaveTable 5530-0002-01.
ssiwiz95 sounds like its for windows 95, but i have it working on 98SE so it might work on other OS's like XP or perhaps 2000? You will have to try that out. I ran the .exe file and installed the drivers (i had to insert the 98SE CD in) and then when it asked if i wanted to continue installing some DOS programs I cancelled it. I just tried it and it works fine! Make sure you plug the speakers in the right plug in the back (its the middle one for me, the others are microphone and line-in) Yay!
