There are a number of different BIOS types, but most PC’s have a BIOS supplied by one of four companies: American Megatrends, Inc. (AMI), Award, Inc., Phoenix Technologies, Inc. or IBM.  Award Software became part of Phoenix Technologies in September 1998 – their main website is the Phoenix Technologies site.

Some BIOS crackers only work with certain BIOS versions and some work better than others.  You may have to try a number of crackers before you find one that works.  I have listed a few sites where you can download free BIOS password crackers below:

• Christophe Grenier
• Eleventh Alliance
• Rempass

Some BIOS’ have pre-installed backdoor passwords that enable access to the system.

For Award BIOS’ try these backdoor passwords (Case sensitive) :

• AWARD_SW
• j262
• HLT
• SER
• SKY_FOX
• BIOSTAR
• ALFAROME
• Lkwpeter
• j256
• AWARD?SW

• AMI?SW
• AMI_SW
• LKWPETER

• CONDO

For PHOENIX BIOS’ try this backdoor password:

In BIOS’ with a release date of December 19, 1996 or later, Award required OEM customers to configure their own security default BIOS passwords using the Award MODBIN.EXE utility, version 4.50.60.
