b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and |
|
BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the |
|
Linksys WPC54G V1 PCMCIA devices. |
|
|
|
Newer 802.11g and 802.11a devices need b43. |
|
|
|
It is safe to include both b43 and b43legacy as the underlying glue |
|
layer will automatically load the correct version for your device. |
|
|
|
This driver uses V3 firmware, which must be installed separately using |
|
b43-fwcutter. |
|
|
|
This driver can be built as a module (recommended) that will be |
|
called "b43legacy". If unsure, say M. |

Say Y, because this information will help you get the driver running. |

This option generates a minimum of log output. |

Include both, Direct Memory Access (DMA) and Programmed I/O (PIO) |
|
data transfer modes. The mode actually used is selectable through |
|
the module parameter "pio". With pio=0 as a module parameter, the |
|
default DMA is used, otherwise PIO is used. |
|
|
|
If unsure, choose this option. |

Only include Direct Memory Access (DMA). |

This reduces the size of the driver module, by omitting the PIO code. |

Only include Programmed I/O (PIO). |
|
This reduces the size of the driver module, by omitting the DMA code. |
|
Please note that PIO transfers are slow (compared to DMA). |
|
|
|
Also note that not all devices of the b43legacy series support PIO. |
|
|
|
You should use PIO only if DMA does not work for you. |
