How To Bypass Bios Passwords. - Read This Amazing Guide!

The BIOS;

Your computers BIOS is the first program that is run when your computer starts.



You can tell the BIOS to ask for a password when it starts, thus restricting access to your computer.
In most cases , It will Be Your Parents/Relative's.

Learn how to bypass it


Their Are 2 Ways Of Doing This. ;


1) Using a Backdoor BIOS Password

Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

AMI Backdoor BIOS Passwords

Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.

Award Backdoor BIOS Passwords

One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.

Phoenix Backdoor BIOS Passwords

Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.

Backdoor BIOS Passwords from Other Manufacturers

Reported BIOS backdoor passwords for other manufacturers include:


VOBIS & IBM = merlin
Dell = Dell
Biostar = Biostar
Compaq = Compaq
Enox = xo11nE
Epox = central
Freetech = Posterie
IWill = iwill
Jetway = spooml
Packard Bell = bell9
QDI = QDI
Siemens = SKY_FOX
SOYO = SY_MB
TMC = BIGO
Toshiba = Toshiba


2) Resetting the BIOS Password using Software

Every system must store the BIOS password information somewhere. If you are able to access the machine after it has been booted successfully, you may be able to view the BIOS password. You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.

You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.

!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.

CmosPwd will recover the BIOS password for the following BIOS versions:

* ACER/IBM BIOS
* AMI BIOS
* AMI WinBIOS 2.5
* Award 4.5x/4.6x/6.0
* Compaq (1992)
* Compaq (New version)
* IBM (PS/2, Activa, Thinkpad)
* Packard Bell
* Phoenix 1.00.09.AC0 (1994)
* Phoenix 4 release 6 (User)
* Gateway Solo - Phoenix 4.0 release 6
* Toshiba
* Zenith AMI

I have found that one of the best ways of getting by the password is clearing the BIOS. This is usually accomplished by one of the following:
1. Take the battery out
2. Short out a specific DIP pin. This usually called CMOS Clear or some other variant. This is usually near the BIOS itself but mileage will vary.
3. Some times you will have to turn the computer on while the Clear CMOS DIP is shorted.
4. You can also leave the battery out for a really long time (a few days).
5. Any combiniation of the above.

This of course will not get the actual password so this will not work if you are trying to be covert. The next time a person boots the machine, they will know something is wrong because there will be no password at all. You will also loose any changes you have made in your CMOS. I have never been a big fan of CMOS passwords because if you have physical access to the machine then it is only a simple matter of taking the case off to get rid of the password. My last machine was a little flaky so I had to reset the BIOS all the time so I had the DIP and procedure memorized.

NEW PROBLEM!!!

Backdoor password don't work....and I can't boot up the programs I need to reset it....usually it needs some boot-up....
and the floppy drive is still not working....HELP!!!
