| 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. | |

| 71 | work for you. | |

| 91 | data transfer modes. | |
| 92 | The actually used mode is selectable through the module | |
| 93 | parameter "pio". If the module parameter is pio=0, DMA is used. | |
| 94 | Otherwise PIO is used. DMA is default. | |

| 102 | Only include Direct Memory Access (DMA). | |
| 103 | This reduces the size of the driver module, by omitting the PIO code. | |

| 110 | This reduces the size of the driver module, by omitting the DMA code. | |
| 111 | Please note that PIO transfers are slow (compared to DMA). | |
| 112 | ||
| 113 | Also note that not all devices of the 43xx series support PIO. | |
| 114 | The 4306 (Apple Airport Extreme and others) supports PIO, while | |
| 115 | the 4318 is known to _not_ support PIO. | |
| 116 | ||
| 117 | Only use PIO, if DMA does not work for you. | |
