... and info on this? i'm wondering if this variant requires custom firmware? board-2.bin isn't happy and i can't find pointers/info on what this is and where the data came from...

i've built the linux wireless master tree and got firmware-6 working ... but
same results. i can get a bit more out of the qualcomm wifi device if i switch

there's something up here and i'm not sure where to begin other than "grab the windows driver firmware and use that" ... but i dont know if that's possible or even how to transform it into a usable form.

any advice?
