| 5 | About this software |
| 6 | ------------------- |
| 7 | |
| 8 | b43-fwcutter is a tool which can extract firmware from various source files. |
| 9 | It's written for BCM43xx driver files. |
| 10 | |
| 11 | The project page is http://bcm43xx.berlios.de/ |
| 12 | |
| 13 | |
| 14 | Usage |
| 15 | ----- |
| 16 | |
| 17 | b43-fwcutter FILE extracts the firmware from a source FILE to |
| 18 | the current directory, creating a directory |
| 19 | "b43" or "b43legacy" with files in it. |
| 20 | b43-fwcutter -i FILE identify the driver file; print information |
| 21 | but don't extract. |
| 22 | b43-fwcutter -w /tmp FILE extract and write firmware to /tmp. |
| 23 | b43-fwcutter -l prints a list of supported driver source files. |
| 24 | |
| 25 | After extraction, copy the "b43" or "b43legacy" directory to your firmware |
| 26 | directory (usually /lib/firmware or similar, see below). Alternatively you |
| 27 | can use the -w option to b43-fwcutter. |
| 28 | |
| 29 | Different distributions use different directories to load firmware from. |
| 30 | If the driver complains about missing firmware files look for the correct |
| 31 | directory. For some distributions you have to use /lib/hotplug/firmware |
| 32 | or /usr/lib/hotplug/firmware but other directories are also possible. |
| 33 | |
| 34 | Because firmware file are stored in big endian, extraction doesn't depend |
| 35 | on the system you're using. You can use extracted firmware from any driver |
| 36 | on any system and also copy the extracted files to any other system (e.g. |
| 37 | if extraction on the target system isn't feasible.) |
| 38 | |
| 39 | |
| 40 | Where can I find some driver source files? |

| 43 | Please check the references at |
| 44 | http://www.linuxwireless.org/en/users/Drivers/bcm43xx#devicefirmware |
| 45 | |
| 46 | It is recommended that you extract firmware for both b43 and b43legacy in |
| 47 | order to support both types of cards on your system. |
