Thank you for the very quick response! Unfortunately, it doesn't seem to work. Perhaps it helps if I give all the details?

What I do is powerup, press Esc, F10. "Enter administrator password", I enter your code 49029118, it says "Invalid password" (3 times). I tried with numpad and keys above the letters. Then it says "System disabled", below that the exact formatting of the code is: [i 56341196] And then the system is frozen on that screen (there is no "OK" button, Esc or Ctrl-Alt-Del don't work). The power button does power down. Powering up again the system boots fine to Windows (which is a broken install). So to be clear the only problem is getting into BIOS setup. Also I can't see where else I can enter the unlock code, apart from using it as administrator password, is that correct?
