Enable b43 drivers in Backtrack5 r2

NOTE: Changing additional options in the ncurses config without knowing what the options do might break your kernel!

• Enabling b43 drivers in BT5 R2 will require recompiling your kernel.

root@bt:~# apt-get dist-upgrade
root@bt:~# prepare-kernel-sources
root@bt:/usr/src/linux# zcat /proc/config.gz > .config
root@bt:/usr/src/linux# make menuconfig

• Configure your kernel to use b43 instead of the default brcmsmac drivers by selecting the BCMA support option. To get to this option, navigate to :

Device Drivers -> Broadcom specific AMBA.

• Add the BCMA support as a module, and "Support for BCMA on PCI-host bus" as shown below

• Exit the ncurses menu config, and build your kernel package:

root@bt:/usr/src/linux# make prepare
root@bt:/usr/src/linux# make
root@bt:/usr/src/linux# make modules_install
root@bt:/usr/src/linux# make install
root@bt:/usr/src/linux# update-initramfs -u
root@bt:/usr/src/linux# update-grub2
