Bad news on this one. By design, there is no way for a user to reset the BIOS Supervisor password (of course, anything can be hacked, but I don't know of any such hack for the ThinkPad T40). Only IBM can do this. You must return the machine to them and pay a fee. You also need to provide proof of ownership so they don't become party to laptop theft.

Hate to see you got the same reply here but that's what I had assumed. There are quite a few defaults for the IBM bios, as provided in the links I sent you but as I said, these have become few and far between since IBM started using EPROM security.
