I am trying to install a mediavision pro audio 3d multi cd fcc#650-0117 -01d with an attached 2x mke Panasonic cd #cr562b into a 486 running win 3.1. I have disks 2 and 3 out of 4 original installation disks for the sound card. I have a downloaded driver for the cd.I have also downloaded the driver for pro audio 3d from this site but can't find pro audio 3d multi cd. I can get the sound card to work by using the 1st downloaded disk and the #2 and #3 original disks but it won't recognize disk #4. The sound works but the driver for the cd asks for the type of sound card and input- output addresses. I can't get past this. Anyone any guesses on where to find the proper driver or how to get disk #4 to load or how to install this cd.Thanks
