Abstract

본 발명은 별도의 하드웨어 로직 추가없이 720킬로 바이트/1.2 메가 바이트/1.44 메가 바이트 겸용 3.5인치 플로피 디스크 드라이브를 사용할 수 있도록한 3모드 플로피 디스크 드라이브 구동 인터페이스 방법에 관한 것으로, 디스켓이 720킬로 바이트 또는 1.44 메가 바이트(즉 2모드)인 경우 플로피 디스크 드라이브와 플로피 디스크 컨트롤러사이의 관계에서 식별이 되고, 1.44 메가 바이트 또는 1.2메가 바이트 인지의 여부가 플로피 디스크 드라이브와 키 보드 컨트롤러사이의 관계에서 식별되어 3모드 플로피 디스크 드라이브를 사용할 수 있게 한다.The present invention relates to a three-mode floppy disk drive drive interface method that enables the use of a 3.5-inch floppy disk drive with 720 kilobytes / 1.2 megabytes / 1.44 megabytes without additional hardware logic. In the case of megabytes (ie 2 modes), it is identified in the relationship between the floppy disk drive and the floppy disk controller. Make the floppy disk drive available.
