are you using the correct SLIC certificate and serial..You need them installed in order to activate. Without them, it is just a bios .. If the bios flashed, then the vista should be activated. They were all correct.
I have 3 computers in my home and 2 of it was activated successfully from the bios by this webboard and correct cert with serial. Anyway, thanks you so much for your great effort and help all along.
