++ This driver is for Tahoe 931/932/971/972 cards
++ If you have such a card, say Y or M here and see
++ <http://www.tahoe.pl/>
++
++ If you want to compile the driver as a module ( = code which can be
++ inserted in and removed from the running kernel whenever you want),
++ say M here and read <file:Documentation/modules.txt>. The module
++ will be called tahoe9xx.o.
++
++ If unsure, say N here.
