It can be made including the process of displaying
이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
일반적으로, 하드디스크(hard disk) 및 플로피디스크(floppy disk) 등은 데이터 파일의 보관에 있어서 반드시 내용이 작성되어 저장되면, 그 내용이 들어있는 위치와 이름 및 만들어진 날짜 등의 정보가 파일배치 테이블(File Allocation Table : FAT)에 기록되어 관리된다.In general, hard disks and floppy disks, if the contents are created and stored in the storage of the data file, information such as the location and name and the date of creation of the contents file file table It is recorded and managed in (File Allocation Table: FAT).
이때, 상기 파일배치 테이블(FAT) 정보가 없는 경우에 파일의 내용을 확인할 수 없다.At this time, if there is no file layout table (FAT) information, the contents of the file cannot be checked.
본 발명은 상기와 같은 원리를 이용하여 시스템의 오프(OFF)시 시스템의 동작에 필요한 기본정보를 시스템 외부의 기록매체로 이동시키고, 시스템에는 기본정보를 삭제시킴으로써 기본정보 없이 시스템이 동작되지 않도록 하여 제3자에게 내용을 공개하지 않도록 한다.The present invention moves the basic information necessary for the operation of the system to the recording medium outside the system when the system is off (OFF) by using the above principle, so that the system does not operate without the basic information by deleting the basic information in the system Do not disclose the content to third parties.
이때, 기본정보로는 분할 정보(partition), 부팅영역 정보(boot sector), 파일배치 테이블 정보(FAT) 등이 사용된다.In this case, partition information, partition information, boot sector information, file layout table information (FAT), and the like are used as basic information.
도 1은 본 발명에 의한 시스템 오프 동작을 나타내는 흐름도이고, 도 2는 본 발명에 의한 시스템 온 동작을 나타내는 흐름도이다.1 is a flowchart illustrating a system off operation according to the present invention, and FIG. 2 is a flowchart illustrating a system on operation according to the present invention.
먼저, 도 1을 참조하면, 사용자가 시스템을 동작시키는 중 시스템 오프(OFF) 신호가 입력되었는지를 계속적으로 판단한다.(S11 및 S12 참조)First, referring to FIG. 1, the user continuously determines whether a system OFF signal is input while operating a system (see S11 and S12).
이때, 시스템 오프(OFF) 신호가 입력되면 시스템의 하드디스크에 저장된 시스템의 동작에 필요한 기본정보를 플로피디스크와 같은 시스템 외부의 기록매체로 복사한다.(S13 참조)At this time, when the system OFF signal is input, basic information necessary for the operation of the system stored in the hard disk of the system is copied to a recording medium external to the system such as a floppy disk (see S13).
그후, 플로피디스크로 상기 기본정보의 복사가 완료되었는지를 판단하고(S14 참조), 복사가 완료되면 하드디스크 내부의 기본정보를 삭제하고 시스템을 오프시킨다. (S15 참조)Then, it is determined whether the copying of the basic information to the floppy disk is completed (see S14). When the copying is completed, the basic information inside the hard disk is deleted and the system is turned off. (See S15)
상기 하드디스크의 부팅에 필수적인 내부 기본정보가 삭제된 상태에서는 하드디스크를 부팅할 수 없어서 시스템이 정상적으로 동작하지 않아 하드디스크에 저장된 데이터의 내용을 볼 수 없다. 즉, 시스템 부팅시 OS(Operation System)가 하드디스크 부팅에 필수적인 분할정보, 부팅영역정보, 파일배치테이블을 읽어들이지 못하여 하드디스크가 정상적으로 동작하지 못하게 되어 시스템이 동작하지 않게 된다.If the internal basic information essential for booting the hard disk is deleted, the hard disk cannot be booted and the system does not operate normally. Therefore, the contents of the data stored on the hard disk cannot be viewed. That is, when the system booting, the OS (Operation System) cannot read partition information, boot area information, and file arrangement table, which are essential for hard disk booting, and thus the hard disk does not operate normally.
한편, 도 2를 참조하면, 시스템 기동시에는 시스템의 오프(OFF) 상태에서 기본정보가 복사된 시스템과는 별도로 보관되는 휴대용 플로피 디스크를 시스템의 드라이버에 장착한 후 시스템 온신호가 입력되는지를 계속적으로 판단하고(S21 참조), 시스템 온 신호가 입력되면 롬 바이오스(ROM BIOS)가 시스템의 장치를 검색하는 포스트 과정이 진행되고, 이 과정 중에 상기 플로피 디스크에 저장된 기본정보 데이터를 읽어들여 하드디스크의 기본 정보영역에 복사한다.(S22 참조)Meanwhile, referring to FIG. 2, at system startup, a portable floppy disk stored separately from a system to which basic information is copied in the system OFF state is mounted in a driver of a system, and then a system on signal is continuously input. If the system on signal is inputted, a post process of ROM BIOS searching for a device of the system is performed, and the basic information data stored in the floppy disk is read during the process. Copy to the basic information area (see S22).
그후, 상기 복사가 완료되면 복사된 데이터가 시스템의 동작에 필요한 기본정보인지를 판단하고(S23 참조), 그 결과가 기본정보인 경우에 시스템을 온(ON) 시킨다.(S24 참조)Then, when the copy is completed, it is determined whether the copied data is basic information necessary for the operation of the system (see S23), and if the result is the basic information, the system is turned on (see S24).
이때, 상기 S23에의 결과가 복사된 데이터가 기본정보가 아닌 경우에 외부로 시스템의 온(ON) 동작 실패를 표시한다.(S25 참조)At this time, when the data copied to the result of the step S23 is not the basic information, the ON operation failure of the system is displayed externally (see S25).
이상에서 설명한 바와 같이, 본 발명에 의한 하드디스크의 부팅방법은 시스템의 동작에 필요한 기본정보를 시스템의 오프(OFF)시 외부의 기록매체에 별도로 보관하도록 하기 때문에 시스템이 제3자에게 입수된 경우에도 시스템이 동작되지 않아 내부에 저장된 데이터의 공개 및 손실이 방지되는 효과가 있다.As described above, the hard disk booting method according to the present invention allows the basic information necessary for the operation of the system to be stored separately on an external recording medium when the system is turned off. Even though the system does not operate, there is an effect of preventing the disclosure and loss of data stored therein.
