The
az driver provides support for the Aztech/PackardBell radio cards.
The Aztech/PackardBell cards are stereo FM tuners that allow tuning in the 87.5-108.0 MHz range. They are capable of reporting signal status (tuned/not tuned, stereo/mono signal) and forcing audio output to mono.
The Aztech cards use only one I/O port. The I/O port is set by the driver to the value specified in the configuration file. The I/O port must be one of 0x350 and 0x358.
