Thank you for very good info. I create new file using my cis dump and
Bromax5v.hex but flash utils told me that there is Check sum error on
line 2 and dont want to flash it. Thing that maybe a dump file is not
valid or corrupted. When i conver dump file from hex to ascii there is some
wrong symbols in PNP ID. The unknow prism2 card is some Proxim OEM card removed
from AP.
