21 This driver should provide support for most Aztech AZT2320 based cards.
22 Several AZT2316 chips are also supported/tested, but autoprobe doesn't
23 work: all module option have to be set.
24
25 No docs available for us at Aztech headquarters !!! Unbelievable ...
26 No other help obtained.

28 Thanks to Rainer Wiesner <rainer.wiesner@01019freenet.de> for the WSS
