  8           b43 is a driver for the Broadcom 43xx series wireless devices.
  9 
 10           Check "lspci" for something like
 11           "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
 12           to determine whether you own such a device.
 13 
 14           This driver supports the new BCM43xx IEEE 802.11G devices, but not
 15           the old IEEE 802.11B devices. Old devices are supported by
 16           the b43legacy driver.
 17           Note that this has nothing to do with the standard that your AccessPoint
 18           supports (A, B, G or a combination).
 19           IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
 20 
 21           It is safe to include both b43 and b43legacy as the underlying glue
 22           layer will automatically load the correct version for your device.
 23 
 24           This driver uses V4 firmware, which must be installed separately using
 25           b43-fwcutter.
 26 
 27           This driver can be built as a module (recommended) that will be called "b43".
 28           If unsure, say M.

 80 
 81           Support for 16bit PCMCIA devices.
 82           Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
 83           devices, but 32bit CardBUS devices. CardBUS devices are supported
 84           out of the box by b43.
 85 
 86           With this config option you can drive b43 cards in
 87           CompactFlash formfactor in a PCMCIA adaptor.
 88           CF b43 cards can sometimes be found in handheld PCs.
 89 
 90           It's safe to select Y here, even if you don't have a B43 PCMCIA device.

100 
101           With this config option you can drive Soft-MAC b43 cards with a
102           Secure Digital I/O interface.
103           This includes the WLAN daughter card found on the Nintendo Wii
104           video game console.
105           Note that this does not support Broadcom 43xx Full-MAC devices.

132           This enables support for devices with N-PHY.
133 
134           Say N if you expect high stability and performance. Saying Y will not
135           affect other devices support and may provide support for basic needs.

142           Support for the LP-PHY.
143           The LP-PHY is a low-power PHY built into some notebooks
144           and embedded devices. It supports 802.11a/b/g

183 
184           This adds additional runtime sanity checks and statistics to the driver.
185           These checks and statistics might be expensive and hurt the runtime
186           performance of your system.
187           This also adds the b43 debugfs interface.
188 
189           Do not enable this, unless you are debugging the driver.
190 
191           Say N, if you are a distributor or user building a release kernel
192           for production use.
193           Only say Y, if you are debugging a problem in the b43 driver sourcecode.
