ABSTRACT:
An initial program loading system in an information processing system containing a central processing unit and at least one peripheral apparatus connected to the central processing unit. The system transfers program data from the peripheral apparatus to the central processing unit. The system then loads the program data in the central processing unit, responding to an IPL request which is input into said initial program loading system. Each peripheral apparatus has a unit for sending a notification to the central processing unit that the peripheral apparatus is ready to transfer the program data to the central processing unit. After the central processing unit receives the notification, the transfer of the program data is carried out. The IPL request may be received in the central processing unit, or each peripheral apparatus. An IPL controller may be provided in the system. The IPL controller may contain units to receive the IPL request, to receive a notification as above from each peripheral apparatus, to determine one peripheral apparatus from which the program data is to be transferred to the central processing unit, and to notify the result of the determination to the central processing unit.
