+	  If you have a wireless card belonging to this class, say Y.
+
+	  Note that the answer to this question doesn't directly affect the
+	  kernel: saying N will just cause the configurator to skip all the
+	  questions about these cards. If you say Y, you will be asked for

+	  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
