Abstract: A process for starting a data processing installation, and associated components, wherein program commands of a bootstrap program are stored in a bootstrap memory unit and, when executing the bootstrap program, a processor controls the transfer of program commands from a reload memory unit to a main memory unit and, after the transfer operation, execution of the program commands stored in the main memory unit during the transfer operation is started, the bootstrap memory unit and/or the reload memory unit being serial-access memory units which are less expensive than memory units used previously.

Abstract: The method effects initialization of successively arranged peripheral equipment (PE1...PEn) that are connected in parallel via an interface (S) to a central equipment (ZE) of a communication system. An access permission signal (zs) is forwarded from peripheral equipment (PE1...PEn) to peripheral equipment (PE1...PEn). The as yet not initialized peripheral equipment (PE1...PEn) addressed by the access permission signal (zs) inhibits the forwarding of the access permission signal (zs) until the access of this peripheral equipment (PE1...PEn) to the interface (S), for accepting an address of the peripheral equipment (PE1...PEn), has been ended. The method enables a maximum configuration freedom with respect to the type and plurality of the peripheral equipment (PE1...PEn). An inoperative peripheral equipment (PE1...PEn) can additionally be localized and an initialization of all intact peripheral equipment (PE1...PEn) can ensue regardless of the position of the peripheral equipment (PE1...PEn) that has failed.
