I have a client's machine on which one of his darling little brats has created or reset the BIOS password and now denies all knowledge of the thing. I seem to recall there is either a means of generating the default password from the Service Tag or, failing that, shorting out one of the motherboard chips. That I have done before but would prefer to know which chip it is. The system is a Dell Dimension 3100. Anyone able to help before I condemn the thing to perdition and a drop kick into the neighbours wheelie bin?
