+ 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.

+ Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
+ 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.
