    The last method to reset BIOS password is the hardware reset. You need to open your computer cabinet and just remove the CMOS battery which is located on the mother board. Once you remove the CMOS battery, wait for some time and once again put the battery back. Now the BIOS information stored in your CMOS memory is erased and when you boot your system next time, it will not ask for the BIOS password.

    Most of the motherboards have a jumpers to clear the CMOS settings including BIOS passwords. Once you set the jumpers as per instructions given there, it will reset the CMOS and u can clear the BIOS password.
