Abstract

1. A method for identifying a system-allied, physically separable program memory in a data processing system comprising a central processing unit, an executive memory and a device for physically introducing a program memory into the system, said method comprising the following steps : a) comparing an identifier stored in said program memory with a reference identifier stored in said executive memory ; b) generating an error signal if said reference identifier does not correspond to said identifier stored in said program memory ; c) disabling, under the control of said error signal, the operation the data processing system, characterized in that a reset signal is generated after an initialization of the data processing system, under the control of said reset signal a start command signal being generated by the central processing unit in order to start said comparison.
