DESCRIPTION
Theaz 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.

BUGS
It is impossible to determine to which frequency the card is tuned. Thus, the driver will report an internally stored value even if it is not correct (changed by some program that uses direct port access).
