Old devices are supported by 15 the b43legacy driver. 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. 19 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. 22 23 This driver uses V4 firmware, which must be installed separately using 24 b43-fwcutter. 25 26 This driver can be built as a module (recommended) that will be called "b43". 27 If unsure, say M. 28 29# Auto-select SSB PCI-HOST support, if possible 30config B43_PCI_AUTOSELECT 31 bool 32 depends on B43 && SSB_PCIHOST_POSSIBLE 33 select SSB_PCIHOST 34 select SSB_B43_PCI_BRIDGE 35 default y 36 37# Auto-select SSB PCICORE driver, if possible 38config B43_PCICORE_AUTOSELECT 39 bool 40 depends on B43 && SSB_DRIVER_PCICORE_POSSIBLE 41 select SSB_DRIVER_PCICORE 42 default y 43 44config B43_PCMCIA 45 bool "Broadcom 43xx PCMCIA device support" 46 depends on B43 && SSB_PCMCIAHOST_POSSIBLE 47 select SSB_PCMCIAHOST 48 ---help--- 49 Broadcom 43xx PCMCIA device support. 50 51 Support for 16bit PCMCIA devices. 52 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA 53 devices, but 32bit CardBUS devices.
