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. | |

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. | |

104 | The actually used mode is selectable through the module | |

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). | |
124 | ||
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. | |
128 | ||
129 | Only use PIO, if DMA does not work for you. | |
