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.

47 select SSB_PCMCIAHOST
48 ---help---
49 Broadcom 43xx PCMCIA device support.
50
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.
55
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.
59
60 It's safe to select Y here, even if you don't have a B43 PCMCIA device.
61
62 If unsure, say N.

93 select B43_DMA
94 select B43_PIO
95 ---help---
96 Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
97 data transfer modes.
98 The actually used mode is selectable through the module
99 parameter "pio". If the module parameter is pio=0, DMA is used.
100 Otherwise PIO is used. DMA is default.
101
102 If unsure, choose this option.
103
104 config B43_DMA_MODE
105 bool "DMA (Direct Memory Access) only"
106 select B43_DMA
107 ---help---
108 Only include Direct Memory Access (DMA).
109 This reduces the size of the driver module, by omitting the PIO code.
110
111 config B43_PIO_MODE
112 bool "PIO (Programmed I/O) only"
113 select B43_PIO
114 ---help---
115 Only include Programmed I/O (PIO).
116 This reduces the size of the driver module, by omitting the DMA code.
117 Please note that PIO transfers are slow (compared to DMA).
118
119 Also note that not all devices of the 43xx series support PIO.
120 The 4306 (Apple Airport Extreme and others) supports PIO, while
121 the 4318 is known to _not_ support PIO.
122
123 Only use PIO, if DMA does not work for you.
