The az driver provides support for the Aztech/PackardBell
The Aztech/PackardBell cards are stereo FM tuners that can
tune in the
87.5-108.0 MHz range. They are capable of reporting signal
(tuned/not tuned, stereo/mono signal) and forcing audio output to mono.
The card is based on the LM7001 chip; see radio(4) for details.
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.
