About specifications

This page contains a list of specifications used to write Linux drivers for several wireless cards, and which, alternatively, can be used to write drivers for any other platforms.

Broadcom hardware specifications

The b43 driver was written based on the reverse engineered specification. This device currently is known to use two different firmware types, each of which changes the behavior of the driver. Because of this we have two different drivers for each handle each firmware. Fortunately we have specifications written for both firmwares.
