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. | |

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

99 | This reduces the size of the driver module, by omitting the DMA code. | |
100 | Please note that PIO transfers are slow (compared to DMA). | |
101 | ||
102 | Also note that not all devices of the b43legacy series support PIO. | |
103 | ||
104 | You should use PIO only if DMA does not work for you. | |
