|  | 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. |

|  | 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. |
