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

+	  Broadcom 43xx PCMCIA device support.
+
+	  Support for 16bit PCMCIA devices.
+	  Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
+	  devices, but 32bit CardBUS devices. CardBUS devices are supported
+	  out of the box by b43.
+
+	  With this config option you can drive b43 cards in
+	  CompactFlash formfactor in a PCMCIA adaptor.
+	  CF b43 cards can sometimes be found in handheld PCs.
+
+	  It's safe to select Y here, even if you don't have a B43 PCMCIA device.
+
+	  If unsure, say N.
+
+config B43_DEBUG

+	  data transfer modes.
+	  The actually used mode is selectable through the module
+	  parameter "pio". If the module parameter is pio=0, DMA is used.
+	  Otherwise PIO is used. DMA is default.
+
+	  If unsure, choose this option.
+
+config B43_DMA_MODE
+	bool "DMA (Direct Memory Access) only"
+	select B43_DMA
+	---help---
+	  Only include Direct Memory Access (DMA).
+	  This reduces the size of the driver module, by omitting the PIO code.
+
+config B43_PIO_MODE
+	bool "PIO (Programmed I/O) only"
+	select B43_PIO
+	---help---
+	  Only include Programmed I/O (PIO).
+	  This reduces the size of the driver module, by omitting the DMA code.
+	  Please note that PIO transfers are slow (compared to DMA).
+
+	  Also note that not all devices of the 43xx series support PIO.
+	  The 4306 (Apple Airport Extreme and others) supports PIO, while
+	  the 4318 is known to _not_ support PIO.
+
+	  Only use PIO, if DMA does not work for you.
