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. | |

78 | Include both, Direct Memory Access (DMA) and Programmed I/O (PIO) | |
79 | data transfer modes. The mode actually used is selectable through | |
80 | the module parameter "pio". With pio=0 as a module parameter, the | |

97 | This reduces the size of the driver module, by omitting the DMA code. | |
98 | Please note that PIO transfers are slow (compared to DMA). | |
99 | ||
100 | Also note that not all devices of the b43legacy series support PIO. | |
101 | ||
102 | You should use PIO only if DMA does not work for you. | |
