Old devices are supported by 16 the b43legacy driver. 17 Note that this has nothing to do with the standard that your AccessPoint 18 supports (A, B, G or a combination). 19 IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints. 20 21 It is safe to include both b43 and b43legacy as the underlying glue 22 layer will automatically load the correct version for your device. 23 24 This driver uses V4 firmware, which must be installed separately using 25 b43-fwcutter. 26 27 This driver can be built as a module (recommended) that will be called "b43". 28 If unsure, say M. 29 30# Auto-select SSB PCI-HOST support, if possible 31config B43_PCI_AUTOSELECT 32 bool 33 depends on B43 && SSB_PCIHOST_POSSIBLE 34 select SSB_PCIHOST 35 select SSB_B43_PCI_BRIDGE 36 default y 37 38# Auto-select SSB PCICORE driver, if possible 39config B43_PCICORE_AUTOSELECT 40 bool 41 depends on B43 && SSB_DRIVER_PCICORE_POSSIBLE 42 select SSB_DRIVER_PCICORE 43 default y 44 45config B43_PCMCIA 46 bool "Broadcom 43xx PCMCIA device support (EXPERIMENTAL)" 47 depends on B43 && SSB_PCMCIAHOST_POSSIBLE && EXPERIMENTAL 48 select SSB_PCMCIAHOST 49 ---help--- 50 Broadcom 43xx PCMCIA device support. 51 52 Support for 16bit PCMCIA devices. 53 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA 54 devices, but 32bit CardBUS devices.
