Abstract
PURPOSE: To obtain the load system which can program the entire surface of one floppy disc without losing conventionality, by sufficiently using the firmware at a central processing unit.
CONSTITUTION: A bus BS is drawn from a central processing unit CPU incorporating the read only memory ROM where the firmware performing the function of the initial program loading is stored, and it is connected with RAM being the main memory unit and the floppy disc FLP via the input and output port FP. With this constitution, the disc FLP is stored with the load address, load length, start address, and system name such as record head address, and these parameter information is read out with the memory ROM when the power supply is applied for the loading, and the system name is stored in the working area WR of the memory unit RAM. Further, the parameter in the disc FLP is sequentially loaded to the memory unit RAM via the port FP not via the processor CPU.
