hello, I only want to add something here and that is the DELL laptops, if there was a BIOS password and the password is somehow forgotten, there is noway(NOWAY) we can bypass or alter the password, because they have a security chip installed , meaning that there is a BIOS chip and another chip(security chip) to store the password.there is a way to reset this security chip by shorting two pins of the chip,but this can damage the main boeard permenantly.anyone can do some google work about( DELL pasword) and can see what am saying here.thank you Tacho
