Gravis UltraSound Plug & Play
The UltraSound Plug & Play sound card makes use of the highly-integrated Interwave chip developed by Advanced Micro Devices. The Interwave chip was developed as the result of a joint venture between Gravis and AMD utilizing Advanced Gravis' UltraSound audio technology. The Interwave chip is the first to provide integration of the MPC-3 multimedia requirements. This integrated technology allows Gravis to deliver more honest reproduction of sound and reduce the card's cost without sacrificing the quality of the other components.

When I hook up my CD-ROM to the PnP, I can't use my CD-ROM. Why??
In Win 95, this is because Windows 95 could not resolve conflicts. To fix this, you must go into Control Panels -> System -> Device Manager -> Hard Disk Controllers. Click on the last device in that list and click the Properties Button. You must then click on the Resources tab. At this point, it says that you must set the resources manually, so click on the Set Resources Manually button. You then can uncheck the 'Automatic Configuration' box and select the resource that needs to be changed (Base Port, IRQ ) until it no longer conflicts. When you are done, click OK, and click OK again when asked to.
In DOS, you must make sure that you initialize the PnP in the Config.sys. To do this, make sure that you place this line BEFORE your CD-ROM driver. To be safe, make sure this line is first (or second if you have a Hard Disk Manager being loaded). The line is:
Device=c:\ultrapnp\IWINIT.exe -bbios ID=GRV00001 Interwave=C:\ultrapnp\iw.ini
The above line assumes you have installed the software in C:\ULTRAPNP. Make changes to match your drive \ directory if necessary.
