AN430TX SPECIFICATION UPDATE 13. System BIOS May Corrupt Audio Add-In Card EEPROM PROBLEM: Audio add-in cards using the Yamaha OPL3-SA2 or OPL3-SA3 audio codec have the same hardware identification number that is used by the Yamaha audio device integrated on the motherboard. This causes the system BIOS to inadvertently write information into the audio add-in card’s serial EEPROM during system startup, thereby corrupting the audio add-in card’s EEPROM contents. IMPLICATION: The audio add-in ca
