Abstract
A method for changing and/or inputting data and programs into at least one first memory ( ) of a computer system, especially for control of operations in a motor vehicle, is described. This method is particularly useful for changing or reprogramming a control unit ( ) of a motor vehicle. The programs are divided into at least one first routine and at least one second routine. At least one second memory ( ) is provided in addition to the first memory, in which a definite division into certain memory regions is provided. The routines and/or data are backed up in the memory regions. Back up copies of the routines and/or data are provided in at least one of the at least two memories prior to the erasing and/or copying and/or reading in of the data and/or routines in the memory regions. These back up copies are either erased or used again as the original after successful programming, but must not remain stored as backup copies or must be input again from the outside.
