I have an IBM T42, but I have the supervisor password set that I have long forgotten. I know about ways to clear the password (if they indeed work) but I have not gotten around it. If anyone knows a solution that does work, feel free to share.
It is in a mint condition, not a single scratch, and I don't want to throw it out for sure. I have an old OpenBSD on it, it is perfect for some light C coding using mg. :)
From my corrupted memory, but I think what you need to do is unplug, pull out the battery, open it up and remove the cmos battery. There should be instructions on the WEB for that. At work, people alawys returned their Thinkpads with that PW set, so I know there is a fix.
But if the password is a harddisk password, you are SOL :( You will need to get a new HD.
If I remember correctly that is not enough, because the supervisor password is stored on the EEPROM chip, so I supposedly have to short some pins.

I am not certain, however! We will see.
Maybe that is what it was, you need to flash the BIOS ?
For the tech people at work it was not a too difficult thing to do.
I am no longer there, so I have no one to ask now :(
