8 b43 is a driver for the Broadcom 43xx series wireless devices.
10 Check "lspci" for something like
11 "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
12 to determine whether you own such a device.
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
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.
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.
24 This driver uses V4 firmware, which must be installed separately using
27 This driver can be built as a module (recommended) that will be called "b43".

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

95 default B43_DMA_AND_PIO_MODE
97 config B43_DMA_AND_PIO_MODE
102 Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
104 The actually used mode is selectable through the module
105 parameter "pio". If the module parameter is pio=0, DMA is used.
106 Otherwise PIO is used. DMA is default.
108 If unsure, choose this option.
111 bool "DMA (Direct Memory Access) only"
114 Only include Direct Memory Access (DMA).
115 This reduces the size of the driver module, by omitting the PIO code.
118 bool "PIO (Programmed I/O) only"
121 Only include Programmed I/O (PIO).
122 This reduces the size of the driver module, by omitting the DMA code.
123 Please note that PIO transfers are slow (compared to DMA).
125 Also note that not all devices of the 43xx series support PIO.
126 The 4306 (Apple Airport Extreme and others) supports PIO, while
127 the 4318 is known to _not_ support PIO.
129 Only use PIO, if DMA does not work for you.
