Micanje BIOS passa na HP stolnom PCju?
 
Imam u skoli hrpu HP dc7700 SFF piceka i postavljeni su setup passwordi. Sad, trebao bih uci u BIOS i promijeniti boot order (dopustili smo samo boot s harda i metnuli setup pass), al je netko napravio tipfeler pri upisivanju passa prvi put pa nemrem uci u BIOS.

Trik s debugom iz DOS-a ne pali, kao ni clear cmos. Backdoor pass?

PS: Naletio sam na ovo, nimalo optimisticno :(
Citiraj:

cant do that for a Compaq/HP. No bios battery, and the password is stored on a "security chip" separate from the bios. So you could even replace the bios, and the password would still be there. HP doesn't give those security chips to anyone either. A lost HP bios password requires the random (?) "unlock hash" that the bios displays, and a phonecall to HP, along with a Faxed signed document stating you are the owner, the serial numbers, and the unlock hash, they then call you and tell you the backdoor key generated from the unlock hash you gave them. Imagine a company IT staff having to do that 100X.

P.P.S: Samo bez moraliziranja i raspravljanja o tome jesam li zdipio PC ili kajaznam... Hvala. :chears:

Uff jbga bojim se da ti nema druge nego isprobati sve moguće vrste tipfehlera (y i z naši znakovi velika i mala slova itd) ili zvati HP jer kako se čini to je jedino rješenje...

Neki laptopi imaju poseban EPROM za zastitu.
Imao sam nesto slicno na IBM.
Treba ti dobar Eprom programator.
Ima ljudi koji rade te stvari malo se raspitaj u okolini.
Cijena je oko 30 eura.
Mislim da ti je bolje zamijeniti plocu.
Pozdrav!
