| 7 | b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and | |
| 8 | BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the | |
| 9 | Linksys WPC54G V1 PCMCIA devices. | |
| 10 | ||
| 11 | Newer 802.11g and 802.11a devices need b43. | |
| 12 | ||
| 13 | It is safe to include both b43 and b43legacy as the underlying glue | |
| 14 | layer will automatically load the correct version for your device. | |
| 15 | ||
| 16 | This driver uses V3 firmware, which must be installed separately using | |
| 17 | b43-fwcutter. | |
| 18 | ||
| 19 | This driver can be built as a module (recommended) that will be | |
| 20 | called "b43legacy". If unsure, say M. | |

| 106 | Please note that PIO transfers are slow (compared to DMA). | |
| 107 | ||
| 108 | Also note that not all devices of the b43legacy series support PIO. | |
| 109 | ||
| 110 | You should use PIO only if DMA does not work for you. | |
