On cards with an OPL4, it would use the entire range, where that last eight bytes are the OPL3-compatible registers. AFAIK the opti93x chips have an integrated OPL3 and cannot be used with an OPL4. > If someone can test if the opti92x PnP has the same problem I would be > grateful. My card doesn't have PnP, but I guess the OPL4 detection wouldn't work on 92x either for the same reason. Regards, Clemens
