These files came with the card. The booklet uses the trade mark name "Media Sound." The chips on the card are OPTi 82C929A, Analog Devices AD1846JP, and Yamaha OPL YMF262-M. Except for the Media Sound logo.bmp, these files match those available from OPTi for the 82C929 chip set. OPTi has an OPTi logo.bmp. The OS2 exe file on the disk wouldn't copy. The OS2 read file refers to the card as "Media Source" instead of "Media Sound."
