7 b43 is a driver for the Broadcom 43xx series wireless devices.
9 Check "lspci" for something like
10 "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
11 to determine whether you own such a device.
13 This driver supports the new BCM43xx IEEE 802.11G devices, but not
14 the old IEEE 802.11B devices. Old devices are supported by
16 Note that this has nothing to do with the standard that your AccessPoint
17 supports (A, B, G or a combination).
18 IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
20 It is safe to include both b43 and b43legacy as the underlying glue
21 layer will automatically load the correct version for your device.
23 This driver uses V4 firmware, which must be installed separately using
26 This driver can be built as a module (recommended) that will be called "b43".

45 bool "Broadcom 43xx PCMCIA device support (EXPERIMENTAL)"
46 depends on B43 && SSB_PCMCIAHOST_POSSIBLE && EXPERIMENTAL
49 Broadcom 43xx PCMCIA device support.
51 Support for 16bit PCMCIA devices.
52 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
53 devices, but 32bit CardBUS devices. CardBUS devices are supported
54 out of the box by b43.
56 With this config option you can drive b43 cards in
57 CompactFlash formfactor in a PCMCIA adaptor.
58 CF b43 cards can sometimes be found in handheld PCs.
60 It's safe to select Y here, even if you don't have a B43 PCMCIA device.
64 # Data transfers to the device via PIO
65 # This is only needed on PCMCIA devices. All others can do DMA properly.
68 depends on B43 && (B43_PCMCIA || B43_FORCE_PIO)
73 bool "Pre IEEE 802.11n support (BROKEN)"
74 depends on B43 && EXPERIMENTAL && BROKEN
76 Support for the IEEE 802.11n draft.
78 THIS IS BROKEN AND DOES NOT WORK YET.
83 bool "IEEE 802.11g LP-PHY support (BROKEN)"
84 depends on B43 && EXPERIMENTAL && BROKEN
86 Support for the LP-PHY.
87 The LP-PHY is an IEEE 802.11g based PHY built into some notebooks
90 THIS IS BROKEN AND DOES NOT WORK YET.

109 bool "Broadcom 43xx debugging"
112 Broadcom 43xx debugging.
114 This adds additional runtime sanity checks and statistics to the driver.
115 These checks and statistics might me expensive and hurt runtime performance
117 This also adds the b43 debugfs interface.
119 Do not enable this, unless you are debugging the driver.
121 Say N, if you are a distributor or user building a release kernel
123 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
126 bool "Force usage of PIO instead of DMA"
127 depends on B43 && B43_DEBUG
129 This will disable DMA and always enable PIO instead.
132 This is only for debugging the PIO engine code. You do
133 _NOT_ want to enable this.
