You are on the right track, does it ask to boot from cd-rom if you have a cd-rom in the machine at bootup? If so make a bootable CD-rom with a cmos killer on it. If the boot order is set at C first then the easiest thing to do would be to remove the hard drive. Boot it then. I bet the sucker won't boot from the hard drive now. Of course some really security concious person may have set the other options at none. Then tear it apart and look for a jumper location with three prongs. it should be located near a battery the size of a quarter.
