Description of the Invention: [Technical Field] The present invention relates to a method for improving information security of a computer system and related computer system, and more particularly to a magnetic area that should be turned on and should be turned off by a power-on password. Ways to improve information security and related computer systems. β[S前技术] The popularity of computer systems has enabled a fast and convenient information society, enabling people to process large amounts of data more efficiently, and companies have switched to computer systems to achieve electronic. Therefore, information security is getting more and more attention. In computer systems, users can install different operating systems in different magnetic zones, but such operations may cause information security problems. In general, when a user wants to use a computer system with an operating system installed, the computer system displays a menu after turning on the power. The "face" is determined by the user which operating system to enter. Security, users can prevent the computer system data from being stolen by setting the power-on password or setting the login password of the operating system. Take the power-on password as an example. When the computer system is turned on, the basic input/output system (BasicI叩ut/〇 Utputs_^, will ask the user to enter the power-on password; if (4) the person who enters the shutdown password is correct, the menu interface can be displayed, the user can choose to enter the specific operating system, and the operating system can also set the login password to the wrong place. If the user's input power-on password is incorrect, the basic input/output system will ask for 3 1380192 to re-enter the password or shut down. This method can prevent unauthorized users from using the computer to prevent the computer system data from being stolen. However, as can be seen from the above, as long as the power-on password is correctly input, the user can select to enter a specific operating system. Under this circumstance, the user may read other (4) and even crack the login password through a certain (four) system. Therefore, if the person who wants to steal the data of the computer system, even if the operating system has been set up The login password 'as long as the user can enter the menu interface, the data can be stolen through other operating systems, and even the login password can be cracked, which may cause significant loss to the individual or the enterprise. [Invention] Therefore, the main purpose of the present invention is to provide a promotion one. The method of information security of a computer system and related computer system. The present invention discloses a method for improving information security of a computer system. The plurality of magnetic regions of the computer system are installed with a plurality of operating systems and correspond to a plurality of passwords. The method includes: displaying a message to request an input signal when the power of the computer system is activated; and starting the operation of the magnetic area corresponding to the password when the input signal meets the password of the plurality of passwords System, and hiding the magnetic region outside the magnetic region corresponding to the password in the complex handle magnetic region The invention further discloses a computer system capable of improving information security, comprising a hardware circuit for performing the function of the computer system, wherein a plurality of magnetic 4 1380192 areas of the hard disk of the hard circuit are installed with a plurality of operations a system, and corresponding to a plurality of passwords; and an execution unit for executing a software, the software includes a message displayed when the power of the hardware circuit is activated, to request an input signal; and the input signal When the password of one of the plurality of passwords is met, the operating system of the magnetic zone corresponding to the password is activated, and the magnetic region other than the magnetic region corresponding to the password in the plurality of magnetic regions is hidden. [Embodiment] Please refer to FIG. 1 is a schematic diagram of a process 10 of an embodiment of the present invention. The process 10 is used to improve information security of a computer system. The plurality of magnetic regions of the computer system are installed with a plurality of operating systems and correspond to a plurality of passwords. The process 10 includes the following steps: Step 100. Start. Step 102: When the power of the computer system is started, a message is displayed to request an input signal. Step 104: When the input signal matches one of the plurality of passwords, activate the operating system of the magnetic zone corresponding to the password and hide the magnetic regions other than the magnetic region corresponding to the password in the plurality of magnetic regions. Step 106: End. According to the process 10 'When the computer system is started, the computer system displays a message to request the user to input the signal; if the input signal matches the password corresponding to a certain operating system, the present invention enters the operating system and closes Corresponds to the magnetic zone of other operating systems. Simply put, for the user, the m-level user inputs the boot code, and if it is correct, it will enter the operating system. In other words, the user does not know that the computer system 5 1380192 is equipped with a home job system. At the same time, since the present invention hides the magnetic area of other operating systems, the user cannot access other lines (4), of course. It is not possible to modify the login of other operating systems. Therefore, the computer system according to the present invention determines the magnetic region to be activated and the corresponding operating system based on the password input by the user. In this way, the data of the computer system of the multi-operation system can be prevented from being stolen to maintain information security. It should be noted that the flow diagram 10 shown in the figure is a schematic diagram of an embodiment of the present invention, and those skilled in the art can make different modifications according to the present invention, and are not limited thereto. For example, with respect to the method of concealing the magnetic zone, the present invention can transparently change the master boot record (Master B〇〇t Re_) of the computer system so that the relevant magnetic zone is hidden to avoid data theft. In addition, if the input signal of the user does not match any of the passwords, the present invention can display a warning message and ask the user to re-enter or shut down. The implementation of the process 10 can be performed in a software mode and executed by an execution unit (such as a basic input/output system) to control the magnetic area to be activated in the hardware circuit, and the related operation method should be a general knowledge in the field. It is well known, so it will not be described. In the computer system of the conventional multi-operation system, as long as the power-on password is correctly input, the user can select the special (4) (four) system, so that the user may read other data of the system through the operating system, or even crack the person. password. Under her, in the invention I's the user's feeling of booting as shown in Figure 2, that is, when the power is turned on, the computer system will ask the user for the power-on password, and then enter the corresponding The work of the system ^ and the age of it (4) unified care. Therefore, if the money is not known to the computer system, it is impossible to access the information of other materials or modify the login password. Jane Lotus ^ In other words, the power-on password of the present invention can be used in addition to verifying whether it can enter the job, which magnetic zone should be turned on and which magnetic zones are turned off. As described above, the present invention determines the magnetic area that should be turned on and should be turned off through the power-on password, and the user does not install other operating systems, and may not access the operating system of other operating systems. Into the whistle of information security. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should fall within the scope of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a flow of a first embodiment of the present invention. FIG. 2 is a schematic diagram of a booting situation felt by a user in an embodiment of the present invention. [Main component symbol description] 10 Processes 100, 102, 104, 106 Steps
