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 found this: http://asknotes.com/2018/09/04/removing-supervisor-password-...

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 :(
