     10	  b43 is a driver for the Broadcom 43xx series wireless devices.
     11
     12	  Check "lspci" for something like
     13	  "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
     14	  to determine whether you own such a device.
     15
     16	  This driver supports the new BCM43xx IEEE 802.11G devices, but not
     17	  the old IEEE 802.11B devices. Old devices are supported by
     18	  the b43legacy driver.
     19	  Note that this has nothing to do with the standard that your AccessPoint
     20	  supports (A, B, G or a combination).
     21	  IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
     22
     23	  It is safe to include both b43 and b43legacy as the underlying glue
     24	  layer will automatically load the correct version for your device.
     25
     26	  This driver uses V4 firmware, which must be installed separately using
     27	  b43-fwcutter.
     28
     29	  This driver can be built as a module (recommended) that will be called "b43".
     30	  If unsure, say M.
