7 | b43 is a driver for the Broadcom 43xx series wireless devices. | |
8 | ||
9 | Check "lspci" for something like | |
10 | "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller" | |
11 | to determine whether you own such a device. | |
12 | ||
13 | This driver supports the new BCM43xx IEEE 802.11G devices, but not | |
14 | the old IEEE 802.11B devices. Old devices are supported by | |
15 | the b43legacy driver. | |
16 | Note that this has nothing to do with the standard that your AccessPoint | |
17 | supports (A, B, G or a combination). | |
18 | IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints. | |
19 | ||
20 | It is safe to include both b43 and b43legacy as the underlying glue | |
21 | layer will automatically load the correct version for your device. | |
22 | ||
23 | This driver uses V4 firmware, which must be installed separately using | |
24 | b43-fwcutter. | |
25 | ||
26 | This driver can be built as a module (recommended) that will be called "b43". | |
27 | If unsure, say M. | |

54 | Broadcom 43xx PCMCIA device support. | |
55 | ||
56 | Support for 16bit PCMCIA devices. | |
57 | Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA | |
58 | devices, but 32bit CardBUS devices. CardBUS devices are supported | |
59 | out of the box by b43. | |
60 | ||
61 | With this config option you can drive b43 cards in | |
62 | CompactFlash formfactor in a PCMCIA adaptor. | |
63 | CF b43 cards can sometimes be found in handheld PCs. | |
64 | ||
65 | It's safe to select Y here, even if you don't have a B43 PCMCIA device. | |

135 | This adds additional runtime sanity checks and statistics to the driver. |
136 | These checks and statistics might me expensive and hurt runtime performance | |
137 | of your system. | |
138 | This also adds the b43 debugfs interface. | |
139 | ||
140 | Do not enable this, unless you are debugging the driver. | |
141 | ||
142 | Say N, if you are a distributor or user building a release kernel | |
143 | for production use. | |
144 | Only say Y, if you are debugging a problem in the b43 driver sourcecode. | |
