Si noti che il tasto associato al simbolo "_" nelle tastiere americane corrisponde al simbolo "?" in alcune tastiere europee; percio' -- per esempio -- occorre digitare AWARD?SW anziche' AWARD_SW quando si usano tali tastiere . Si ricordi , inoltre, che le password sono Case Sensitive. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

<<< Torna all'indice Ringraziamenti ad - Elf Qrin (http://www.elfqrin.com/) Se non potete accedere
al pc (password d'avvio), andate allo Se invece avete accesso al vostro pc, potete provare
le seguenti procedure per tentar di decifrare la password
o invalidare i contenuti della ram CMOS in cui essa *potrebbe*
esser memorizzata. Step A] Decodifica Password Scaricate "CmosPDW" e"Bios310" dalla sezione "Utilities"-->"Bios Utilities". Lanciate tali tools sul vostro pc : non tentate ancora di cancellare la CMOS! Se non riuscite a decodificare la password con CmosPWD , tentate di scoprirla usando il "brute force attak" contenuto nell'utility "Bios310" . Invalidare la CMOS RAM :
Procedura Software Step B] Cancellazione Cmos Se il "brute force" attak non ha funzionato e se la password non e' memorizzata nella eeprom di sistema , potete tentare di invalidare i contenuti della ram cmos, usando varie procedure sia hardware che software.Qualunque sia il metodo usato , quando si cancellano i contenuti della CMOS non solo la password , ma anche tutti gli altri parametri bios di configurazione verranno resettati ai valori di default; quando effettuerete di nuovo il boot per la prima volta dopo un cmos-reset , dovrete entrare nel menu' di configurazione del setup bios e risistemare tutti i parametri di configurazione. Potete usare anche Bios310 per effettuare il backup dei dati cmos, ma non so se esso salva anche la password: provate. Procedure B-1] Cancellazione della CMOS tramite uso del DEBUG Usate il comando MS-DOS DEBUG in ms-dos puro (non in una shell di windows). Una volta avviato debug, digitate i seguenti comandi interni: ( per bios AMI/AWARD ) O 70 17 O 71 17 Q ( per bios PHOENIX ) O 70 FF O 71 17 Q ( per bios Generici ) O 70 2E O 71 FF Q Nota la prima lettera e' una "O", non il numero "0". Le stringhe che seguono la "O" sono numeri esadecimali. Procedure B-2] Cancellare la Cmos usando "CmosPWD /k " o "Bios310" Scaricate ed usate queste due utilities dalla sezione
"Utilities" -->"Bios Utilities" . Invalidazione della CMOS RAM :
Procedura Hardware Procedura B-3] Cortocircuitare o Aprire il jumper "Cmos Clear" Cercate sul manuale della mainboard lo speciale jumper "clear cmos" o "reset cmos" e cortocircuitatelo (chiudetelo) o apritelo secondo quanto indicato. Procedura B-4] Rimozione della Batteria che alimenta la Cmos Se non riuscite a trovare il jumper "clear cmos" , provate a rimuovere la batteria della cmos (in alcuni modelli di mobo la batteria e' saldata all'interno della RTC ) . In alcune mobo la batteria ha la forma di un bottone (sui vecchi pc essa invece si presenta come un piccolo cilindro blue saldato sulla motherboard; in tal caso dovete dissaldarla e risaldarla). Lasciate la batteria scollegata per almeno 15-30 minuti o piu', quindi reinseritela: i contenuti della cmos dovrebbero esser stati canncellati. Procedura B-5] Cortocircuitare i pin del chip Un altro modo per cancellare la CMOS RAM prevede la
messa in cortocircuito di due pins del BIOS chip (<ndr>
RTC chips ..? ) per qualche secondo.
Potete usare un pezzetto di filo elettrico . Assicuratevi
che il pc sia spento prima di effettuare questa
operazione. CHIPS P82C206 (square) Cortocircuitate i pins 12 and 32 oppure i pins 74 and 75. gnd 74 |__________________ 5v 75--| | | | | | | CHIPS | 1 * | | | P82C206 | | | | | |___________________| | | | | 5v 12 gnd 32 OPTi F82C206 (rectangular) Cortocircuitate i pins 3 and 26 . 80 51 |______________| 81 -| |- 50 | | | | | OPTi | | | | F82C206 | | | 100-|________________|-31 || | | 1 || | | 30 3 26
I chips Dallas DS1287 , DS1287A, ed i chips
compatibili Benchmarq bp3287MT e bq3287AMT hanno la
batteria inserita all'interno del proprio contenitore. La
batteria ha una durata di circa 10 anni. Le mainboard che
usano tali chips in genere non hanno altre batterie
addizionali . Quando la batteria si scarica, occorre
sostituire l'intero chip (<ndr> in realta' , spesso,
la batteria e' saldata a due pins del chip: facendo molta
attenzione e' possibile dissaldarla e sostituirla. Spesso,
pero', il contenitore plastico esterno del chip e'
sigillato con materiale siliconico). __________ 1 -| * U |- 24 5v 2 -| |- 23 3 -| |- 22 4 -| |- 21 RCL (RAM Clear) 5 -| |- 20 6 -| |- 19 7 -| |- 18 8 -| |- 17 9 -| |- 16 10 -| |- 15 11 -| |- 14 gnd 12 -|__________|- 13 NOTE: Sebbene siano chips da 24-pin, sui chips Dallas possono mancare 5 pins, essi sono pins non usati.

Toshiba | Ols laptops | Hold down left shift key when you start it up | |
Laptops | To reset the password of a Toshiba,
you can use KeyDisk. (see CmosPWD
tool)
Note: The "KeyDisk Creation Utility" is contained in "CmosPWD" tool (downloadable from "Utilities"--> "Bios Utilities" section ). However. to manually create a Toshiba Keydisk, take a 720Kb or 1.44Mb floppy disk, format it , then use a hex editor such as Hex Workshop to change the first five bytes of the second sector (the one after the boot sector) and set them to 4B 45 59 00 00 (note that the first three bytes are the ASCII for "KEY" :) followed by two zeroes). Once you have created the key disk put it into the notebook's drive and turn it on, then push the reset button and when asked for password, press Enter. You will be asked to Set Password again. Press Y and Enter. You'll enter the BIOS configuration where you can set a new password |
