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.

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

63 If unsure, say N.

89 and embedded devices.

122 This will disable DMA and always enable PIO instead.
123
124 Say N!
125 This is only for debugging the PIO engine code. You do
126 _NOT_ want to enable this.
