Forget about drivers from Anchor. It's more easier than you think! This driver works with the Opti 82C924 chip in combination with the CS4231A-KL and yamaha OPL YMF262-M chips.
Revision 06 of the card. This driver was hard to find. I did try the normal win95 drivers from Opti924, but this didn't work. After installing these updated drivers, everything worked perfect! Important note install the card from control panel-add new hardware-manual instal-other devices-use disk from manufacturer. Read readme.txt!
Not tested under win98. If this driver works for you, or you have any questions drop me a line! driver found on the Opti ftp server.
