Abstract

PURPOSE: To use loader program in common to different systems, by executing the loading of system through the use of transfer managing program inserted to the system program in addition to the loader program of fixed memory.
CONSTITUTION: After the application of power supply, the loader program of an ROM3 is initially set with a system control section 1, the head address of an RAM4 storing the transfer information is fed to floppy disc control section 2, and the number of transfer bytes is set to a control section 1. Further, the progress of the loader program is made by the increment of the control section 1 and the transfer start instruction outut from the memory 3 is interpreted at the control section 1. Further, the floppy disc 5 is controlled at the control section 2 to start the data read and detect the data block, the control section 1 is interrupted, and an A register 12 of the control section 1 is loaded under the control of ROM3. Further, the program for the entire system can be executed with the loader program of the ROM3.
