| If your computer won't boot without a password or you need a password to enter the computer set-up or change the settings, then you have a BIOS password set. BIOS is an acronym for basic input/output system. The BIOS is the basic instruction set that "teaches" the computer how to access disk drives, keyboard, display, etc. The BIOS is typically placed on a ROM chip in the computer, hence the term ROM BIOS. The ROM BIOS allows the computer to boot itself. The BIOS is required to boot the computer. Thus, if the BIOS is password protected, the computer will not boot (or you will not be able to enter or change the BIOS settings.) | |||||||
| 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. | |||||||
| Additional security features have been built into laptop computers. These usually include a hard disk password and a more secure BIOS system

| For Award BIOS' try these backdoor passwords: AWARD_SW j262 HLT SER SKY_FOX BIOSTAR ALFAROME Lkwpeter j256 AWARD?SW LKWPETER syxz ALLy 589589 589721 awkward CONCAT d8on CONDO j64 szyx | |||||||
| For AMI BIOS' try these backdoor passwords: AMI BIOS PASSWORD HEWITT RAND AMI?SW AMI_SW LKWPETER A.M.I. CONDO | |||||||
| For PHOENIX BIOS' try this backdoor password: phoenix |
to use these backdoor passwords on a system (even just as a test), we would appreciate
knowing whether these backdoors have worked for you.
| HARD DISK LOCKS |
| Some laptops provide a utility to lock a hard disk with a password. These passwords are not the same as BIOS passwords. Moving a locked hard disk to another machine will not unlock it, since the hard disk password is stored in the hard disk firmware and moves with the hard disk. Also, adding a new (unlocked) hard disk to a locked machine may cause the new hard disk to become locked. Also, note that hard disk lock passwords cannot be removed by reformatting the disk, fdisk or any other software procedure (since the disk will not allow and reads or writes to the disk, it cannot be reformatted. ) Usually, the BIOS password and hard disk lock passwords are set the same by a user and we can recover the BIOS password directly from the laptop security chip (after it is removed from the system board.) However, it is possible that the BIOS password and hard disk lock passwords may be set different. In this case the BIOS password will not unlock the hard disk. You can test to determine if your hard disk is locked by attempting to access it in another laptop |
