This technique no longer works. I work for Toshiba and I know that all the new corporate models store the password in non-volatile flash. There is a reset jumper but it only changes the CMOS settings to their defaults, the password remains. The only way to get rid of it (without changing the motherboard) is to send it in. A challenge code must be sent to one of the very few authorised Toshiba employees capable of returning a response code.
