| 8 | b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and |
| 9 | BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the |
| 10 | Linksys WPC54G V1 PCMCIA devices. |
| 11 | |
| 12 | Newer 802.11g and 802.11a devices need b43. |
| 13 | |
| 14 | It is safe to include both b43 and b43legacy as the underlying glue |
| 15 | layer will automatically load the correct version for your device. |
| 16 | |
| 17 | This driver uses V3 firmware, which must be installed separately using |
| 18 | b43-fwcutter. |
| 19 | |
| 20 | This driver can be built as a module (recommended) that will be |
| 21 | called "b43legacy". If unsure, say M. |

| 100 | |
| 101 | Also note that not all devices of the b43legacy series support PIO. |
| 102 | |
| 103 | You should use PIO only if DMA does not work for you. |
