how to get firmware FROM card?

[Bc. Michal Semler]

Hi,

I got card xi-330:

kernel:ident:nic h/w:id=0x800c 1.0.0
kernel:ident:pri f/w:id=0x15 1.1.4
kernel:ident:sta f/w:id=0x1f 1.8.3 

It's ids looks like my xi-325:

wifi0: NIC: id=0x800c v1.0.0
wifi0: PRI: id=0x15 v1.1.1
wifi0: STA: id=0x1f v1.8.0

So I would like to get firmware FROM 330 and flash it into 325 - How to get 
it?

All around the world are only howtos how to reflash card, but non how to get 
firmware from it.

Thanks guys

M.
