| 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. |
