Some MEDION PCs have hidden BIOS settings. To get to them, get into the BIOS and press F11. If you're asked for a password, try
am8888egc. Maybe you can even omit the last letter.
According to a MEDION employee, there are only 2 employees who know this password. Also it shouldn't be leaked to the net so that no one fools around with the settings. Well, IMHO everyone should decide for his own whether he wants to risk damaging his PC or not. But I guess the newer BIOSes ask for another password.
