A computing system includes a codec device, a basic input-output system including both configuration data and feature data for the codec device, and a device driver for the codec device. The basic input-output system configures the codec device based on the configuration data. The device driver reads the feature data from the basic input-output system and enables one or more features of the codec device based on the feature data. In various embodiments, the device driver is WHQL certified and is included in an automated operating system upgrade of the computing system. Because the feature data is in the basic input-output system, the feature data is preserved during the operating system upgrade of the computing system. In some embodiments, the device driver enables one or more features of an application program based on the feature data.
