the bios stored in the non volatile memory flash as a result of which it is put into an operational state the operating system is provided with two hierarchical layers as ks proceeding from which the data processing system can be accessed differently from a kernel layer ks programs disposed therein can access hardware elements of the data processing system in the kernel layer a driver program sniflash inter alia is assigned which is able to read the data from the non volatile memory flash to erase data and to write data to the non volatile memory flash the second layer of the operating system the application layer as is assigned application programs that are not permitted to access parts of the data processing system which adversely affect or circumvent the security of the operating system one application program which is disposed in the application layer as is the application program deskflash which is provided for the loading of a new bios version n 13 bios by use of the application program deskflash and the driver program sniflash data can be interchanged across the layer boundaries between application layer as and kernel layer ks the application program deskflash can be performed directly on the data processing system by being called by the user of the system as an alternative to this the application program deskflash can be started by a remote access with the aid of a software distribution tool with the aid of the software distribution tool a system administrator can communicate parameters to selected data processing systems via a network that connects a plurality of the data processing systems the parameters starting a batch run on the respective data processing systems the parameter transfers that.
