+ A driver 802.11b wireless cards based on the Atmel fast-vnet
+ chips. This driver supports standard Linux wireless extensions.
+
+ Many cards based on this chipset do not have flash memory
+ and need their firmware loaded at start-up. If yours is
+ one of these, you will need to provide a firmware image
+ to be loaded into the card by the driver. The Atmel
+ firmware package can be downloaded from
+ <http://www.thekelleys.org.uk/atmel>
