Description

Computer system using multi operating system}

The present invention relates to a computer system using multiple operating systems, and more particularly, a plurality of hard disks (HDDs) are installed in one computer and connected to a plurality of communication networks, so that an operating system and a communication network can be selected and used by a user. It relates to a computer system using multiple operating systems.

In general, a personal computer (PC) cannot do anything without running an operating system, that is, software that provides an environment for using other software in the PC. When the user turns on the computer's power switch, it does not seem to do anything for a few seconds, but the computer actually does a complicated set of operations to make sure that all the components are working properly and to warn the user if something goes wrong. This behavior is called 'boot up' or 'booting', and booting on a PC is necessary to keep all the components sufficient to load the operating system.

A computer system typically consists of hardware such as a central processing unit (CPU), memory and input / output devices, applications such as compilers, database systems, video games and business programs, users who are people or other computers, and operating systems. It is done.

The operating system is a program that acts as an interface between a computer user and computer hardware. The operating system is used to conveniently use a computer and to efficiently use computer hardware. In other words, to create an environment for the user to run the program.

Currently, only Windows-MS, which is considered as MS-DOS (hereinafter referred to as DOS) as an operating system in personal computers, has been developed and used. Such operating systems are so large that they employ a method such as reloading a single operating system into system memory using a file using an input / output driver or a specific interface routine. For example, to run a DOS operating system, the PC performs a boot operation that requires loading DOS from disk into RAM memory before the operating system can run.

The boot is done entirely by the PC without the help of an external operating system. It does two things: run a power-on-self-test (POST) and search for a drive for the operating system. When this feature is complete, the boot operation begins reading the operating system and copying them into RAM. When parts of the operating system are loaded from disk, the BIOS is added to the operating system, which is then connected with the device driver to federate and perform functions.

On the other hand, the personal computer is to use a variety of applications, in which case each application is not easy to use or use because of adopting a different operating system. In order to solve this problem, real-time operating systems (R.T.O.S: Real Time Operating Systems), which store a small size boot sequence in a ROM base, are appearing one after another.

However, this real-time operating system (RTOS) secures the shortcomings of the existing computer that operated a large amount of operating system, but it also is inconvenient for general users because there is no integrated software platform. It's a difficult problem. Here, the platform refers to a system based on a higher system in the computer field. For example, MS-DOS is the platform for MS-Windows running on MS-DOS, and MS-Windows is the platform for applications running on MS-Windows.

In addition, an environment provided by a certain software may be called a platform. For example, the environment provided by MS-Windows is the platform of MS-Windows. That is, there is a problem that a booting mechanism for booting each operating system is not provided in a situation in which a real-time operating system (R.T.O.S) having different software platforms is mixed. Due to the above problem, a system using most real-time operating systems (RTOS) connects a ROM having a boot code to a primary power source regardless of user requirements (regardless of user selection). There was a problem that the system is always started and powered on at the same time.

On the other hand, with the recent rapid spread of personal computers (personal computer), the use of a computer to create a document, or to manage the stored information is increasing. In this case, the method of storing the information is to print the document using an output device such as a printer, and to store the document, and to store a hard disk or a floppy disk or other information storage medium. The method of storing and storing the relevant information is mainly used. At this time, in order to prevent the leakage of the information, store the floppy disk or other storage medium in which the information is stored in a separate storage space with a lock device, or set the lock key mounted on the computer body to the lock position of the computer It prevents use.

However, recently, due to the rapid spread of the Internet (inter-net) to enable two-way communication between computers, it is possible to check the information stored in the computer with another computer. As a result, the security status of the information stored in the computer is poor, and computer crimes such as theft and destruction of information are proliferating.

In particular, in public institutions that handle confidential documents, and research institutes such as financial institutions and large corporations, the information security of such computers has become a very important factor, and thus the necessity of computer security devices has been highlighted.

However, as the security devices currently used do not perform their functions properly, a technique for preventing the leakage of information by installing a plurality of hard disks having different operating systems in one computer has been proposed.

In the prior art, if there are two physical hard disks, one of the hard disks is installed as 'Windows 98', and the other hard disk is installed as 'Windows 95'. It was possible to change the IDE cable only by connecting the cable directly to the user's desired hard disk, which leads to the unnecessary process of removing the hardware every time the system is to be changed. There is a problem that there is a risk of exposing or losing important data to the outside through infection of virus or virus.

The present invention has been made to solve the above problems, the object is to connect two hard disks and four communication networks having its own operating system to one computer to be able to use the operating system and communication network at your discretion It is to provide a computer system using multiple operating systems that can reduce the office space by allowing many computers to cope with a single computer.

In addition, another object of the present invention is to physically block the remaining hard disks and communication networks that are not selected in addition to the hard disks and communication networks selected by the user among the plurality of hard disks and communication networks through the relay switch and the cable signal control through an external communication network It is to provide a computer system using multiple operating systems that completely prevents intrusion or virus infection and spread of external hackers and improves the security and safety of internal data by making access impossible.

In addition, another object of the present invention is to configure the circuit automatically according to the configuration environment of the system without disassembling or replacing the internal cable of the operating system when the boot type of the operating system is different so that the bootable in various forms regardless of the operating system By providing a computer system using multiple operating systems that can improve the user's convenience.
