The afterburner bit is not used in the driver. > BFL_FEM to 1 (0x4849 or 0x4A49) introduces the "ping cycle" bug, most likely > because the card doesn't actually support the Front-End Module.

As the card doesn't have a BT chip, this is the correct thing to do. > So, it looks like BoardFlags was intended to be 0x4249, but I'm not too sure on the afterburner bit. The packaging box of my card does not tell anything about supported rates beyond 54MBit. So it most likely does not support afterburner. > Asus incorrectly sets it to 0x0049, which completely breaks transmission in > b43. > > "0x0001: BFL_BTCOEXIST: Board implements Bluetooth coexistance[sic]".

That bit is most likey what is actually the wrong one. -- Greetings Michael. _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
