Titolo: Pasword di BIOS

Ciao!
Ho avuto in regalo un vecchio 486, ma come l'accendo mi esce la password di
bIOS.
Nessuno conosce questa password, né chi me l'ha regalato, né chi utilizzava
quel pc.
Come posso fare per eliminarla?

Se non sbaglio collegandoti al sito della scheda madre del bios in
questione potrebbero rilasciarti una specie di chiave universale!
Ma attento che non lo fanno tutti
Ciaooo

Apri il case e controlla marca e modello della scheda madre, dopodichè 
cercane gli schemi su internet (se hai fortuna lo schema è incollato 
all'interno del case)
Sono sempre presenti dei jumper per flashare a zero le bios pasword: li 
ponticelli, accendi il pc per un paio di secondi, lo spengi e deponticelli 
i juper e il gioco è fatto

Ho dei forti dubbi che con un "vecchio" 486 .....semmai tenterei di trovare
una
"master password"....
     BIOS DEFAULT PASSWORDS

We all love BIOSes right? Those lovely things that control the entire PC,
wouldn't it be a
shame if a hacker got hold of the password to the brain of the mother-board?
One option is to modify the hardware, either by taking out the CMOS battery
(usually a
penny sized silver thing obviously removable or by setting a jumper to
disable the
password/wipe the CMOS, the problem with these methods is that not every
hacker walks around
with a screw driver and a stack of motherboard manuals.
So alternatively you can use the BIOS backdoor passwords that the "security
concious"
COUGH-COUGH manufactures left in as a quick way of modifying BIOSes and
helping people out of
the shit, oh and as if by magic, here's a list of the master-passes that
we've come across.

New Phoenix    According to Phoenix "There is no 'backdoor' password unless
the
    computer manufacturer modified the BIOS to have one.", this is yet to
    be seen :-)
All master-passes are case-sensitive so keep ya eyes on the 2nd LED along
(and I don't mean
