1. A system able to recognize hardware resources of a computer, said system comprising: said computer comprising: a system serial number; and a broken hardware unit comprising: a non-volatile memory unit comprising a read/write non-volatile memory field; and enablement definition data relating to functions of said broken hardware unit; a power unit starting said computer; a control mechanism reading said read/write non-volatile memory field to acquire a previously entered system serial number; a processor determining if said previously entered system serial number acquired from said read/write non-volatile memory field is the same as said system serial number and, when said previously entered serial number and said system serial number do not match, preventing acceptance by said computer of said enablement definition data of said broken hardware unit so as to prevent addition of capacity and features of said broken hardware unit and outputting an error message.
