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. | |

42 | Say Y, because this information will help you get the driver running. | |
43 | This option generates a minimum of log output. | |

62 | ---help--- | |
63 | Include both, Direct Memory Access (DMA) and Programmed I/O (PIO) | |
64 | data transfer modes. The mode actually used is selectable through | |
65 | the module parameter "pio". With pio=0 as a module parameter, the | |
66 | default DMA is used, otherwise PIO is used. | |

68 | If unsure, choose this option. | |

73 | ---help--- | |
74 | Only include Direct Memory Access (DMA). | |
75 | This reduces the size of the driver module, by omitting the PIO code. | |
76 | ||
77 | config B43LEGACY_PIO_MODE | |
78 | bool "PIO (Programmed I/O) only" | |
79 | select B43LEGACY_PIO | |
80 | ---help--- | |
81 | Only include Programmed I/O (PIO). | |
82 | This reduces the size of the driver module, by omitting the DMA code. | |
83 | Please note that PIO transfers are slow (compared to DMA). | |
84 | ||
85 | Also note that not all devices of the b43legacy series support PIO. | |
86 | ||
87 | You should use PIO only if DMA does not work for you. | |
