|You may want to take it to repair shop to do this but...|
Every computer has a small battery on the motherboard, most
are soldered into place, some have a socket where the
battery sits and it can be easily replaced. Remove that
battery, let the computer sit for a while and when you reinstall
it, with any luck (providing the capacitors don't keep the bios
charged up) your password will be cleared. HOWEVER, so
will all of your other bios info.
Other than that, there are some utilities out there that claim to
hack the password out of your bios. I wouldn't trust them.
Call the manufacturer and see if they have any utilities to
remove the password.
