PROCESS AND DEVICE FOR LOADING DATA FOR BASIC SYSTEM ROUTINES OF A DATA PROCESSING SYSTEM

摘要

In new operating systems having two layers with different access tokens, access to a memory (flash) for basic system routines (BIOS) is possible for safety reasons only from a core layer (KS), but not from an application layer (AS). Access to the memory (Flash) is ensured without infringing safety regulations, and a new version of basic system routines (N_BIOS) can thus be made available to a data processing system, by providing in each layer a program (DeskFlash, SniFlash) capable of running in the respective layer.
