eeprom sia installata sulla vostra mainboard. Ci sono due tipi di
memorie flash eeprom, Large Block and Small Block. Noi

sul monitor apparira' la data di rilascio del BIOS ed una lettera
, che sara' "L" oppure "S": dal tipo di
lettera potete dedurre anche il tipo di flash eeprom installata e
quindi anche il corretto aggiornamento bios da usare.
