I want to upgrade the firmware of two cards with the 1.4.2 secondary firmware
but I'm lost.
I'll try the RAM-download you have explained and If it works I prefer to chage the firmware forever.
¿what I need to do it? ¿a flash-download? ¿could you please point me to some web where explain how to do it? ¿Can it be done under linux or i need another S.O.? ¿Is dangerous?
