7 | b43 is a driver for the Broadcom 43xx series wireless devices. | |
8 | ||
9 | Check "lspci" for something like | |
10 | "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller" | |
11 | to determine whether you own such a device. | |
12 | ||
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 | |
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. | |

68 | Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA | |
