..::You can change the world with the knowledge::..

Welcome to the blog this simple basic networking. This post I give a tips to break into the Bios password. Maybe you need now, just in the try on your computer.

Here are the steps to break the BIOS password: 

1. Standard BIOS backdoor passwords 
By typing a password according to the manufacturer's name (try one, and note the size of the letters) as follows:

AWARD BIOS
01322222, 589,589, 589,721, 595,595, 598,598, AWARD SW, AWARD_SW, Award SW, AWARD PW, _award, awkward, J64, j256, j262, j332, j322, HLT, SER, SKY_FOX, Ally, Ally, Condo, CONCAT, TTPTHA , aPAf, HLT, KDD, ZBAAACA, ZAAADA, ZJAAADC, djonet.

AMI BIOS
AMI, AMI, AMI SW, AMI_SW, BIOS, PASSWORD, Hewitt RAND, Oder

PHOENIX BIOS
BIOS, CMOS, phoenix, PHOENIX

If the above fails, other passwords to try (for AMI, AWARD, BIOS Phoenix or other) are: lkwpeter, lkwpeter, BIOSTAR, biostar, BIOSSTAR, biosstar, ALAFAROME, Syxz, Wodj

2. Through open the BIOS Software 
If the manner of the above fails, you can open the bios password using the MSDOS DEBUG utility. You should do it in pure MSDOS mode, instead of the MSDOS shell in Windows. After logging in debug prompt, type the following command:

Go into DOS mode after the DOS prompt c: \> type DEBUG like this
c: \> DEBUG
For the next type
o 70 2e
o 71 ff
Q
On the screen will look like this c: \> DEBUG
-O 70 2e
-O 71 ff
-Q
after typing in your Q will exit the debug that indicates you're done. Next Restart your computer, press DEL and CONGRATULATIONS you can log into the BIOS.
For AMI / AWARD BIOS
O 70 17
O 71 17
Q
For PHOENIX BIOS
O 70 FF
O 71 17
Q
GENERIC applies to all AT motherboard (XT boards do not have CMOS)
O 70 2E
O 71 FF
Q

Description: The first character is the letter O not the number 0.
After performing a command - the command above, restart the computer to see the results. Congratulations to work.

3. Password hacking Bios By Removing the CMOS Battery 
The most potent and most cepet in my opinion is by disconnecting the CMOS battery you insert any of the characters one by one like the technique above. This technique is 99% guaranteed to succeed because I have tried from various types of motherboards.

How to practice: Remove the CMOS battery and turn on the computer without the battery and try to get into the Bios. If you have not managed to turn off the computer and wait 10 minutes and then turn on again without the battery and try to get into the Bios.
