A bios password can be bypass by several methods
>Bios password cracking software.
(Cmos password recovery tools 3.1)
>Using a manufacturers backdoor password to access the BIOS.
>Reset the CMOS using the jumpers or solder beads..
(Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings)
>Removing the CMOS battery for at least 10 minutes.
(Remove motherboard battery for 10 minutes then putthe battery again)
>Overloading the keyboard buffer.
(On some older computer systems, you can force the CMOS to enter its setup screen on boot by overloading the keyboard buffer. This can be done by booting with the keyboard or mouse unattached to the systems, or on some systems by hitting the ESC key over 100 times in rapid succession)
>Using a professional service.
(If the manufacturer of the laptop or desktop PC can't or won't reset the BIOS password, you still have the option of using a professional service. Password Crackers, Inc., offers a variety of services for desktop and laptop computers for between $100 and $400.)
