To make a device that you connect to your parallell port, a lot of Toshiba computers remove the password when you boot it up. The device, named "loopback" ,could be made out of any parallell wire with 25pins connectors (db25). Connect these pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, 18-25
以前听说过,但没实践过,你可以试一下,司马懿呗:)...
