Abstract

PURPOSE: To enable to perform an initial loading, by transmitting the media type discriminating information to a floppy disc controller, in the system in which the memory floppy disc controller is commonly connected.
CONSTITUTION: When the loader device is a floppy disc, CPU1 produces the cylinder command to read out the index information of the floppy disc. The media type is discriminated from this information and the information discriminated is transmitted to the input and output device 7 as the disc parameter. In the floppy disc controller of the input and output device 7, based on this device parameter, command processing after that is made. Further, when the media is inserted, CPU1 makes setting of the device parameter to this device the same as initial loading.
