| 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. |

| Include both, Direct Memory Access (DMA) and Programmed I/O (PIO) |

| ---help--- |
| 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. |
