BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system that facilitates selection and switching of a work mode, and more particularly to a computer system that facilitates selection and switching of a work environment using a plurality of power buttons.

Due to the expansion of computer usage and application fields, the necessity of operating various types of operating systems (OSs) or working environments in one digital computer system is increasing. Accordingly, many personal computers (PCs) have recently emerged. OS or work environment is supported.

In particular, in Windows 98, a single PC allows multiple users to work in their own working environment, which requires the PC to enter the user's ID and password at boot time. (This is called the family log-on function.) The PC then operates in the working environment corresponding to the user's ID and password.

Fig. 1 is a flow chart showing the operation of a conventional computer system using such a Windows 98 OS.

As shown in FIG. 1, when power is supplied to a computer system, a central processing unit (CPU) of the computer is configured by a basic input output system (BIOS) program installed in a ROM. Initialization process is performed to operate, and a power on self test (POST) process is performed to check whether each hardware is abnormal. (S11)

After the POST process is performed, the CPU loads and executes IO.SYS and MSDOS.SYS in RAM at specific locations on the auxiliary storage by the startup program in the BIOS program. (S12) Then, the CPU executes the CONFIG.SYS file and boots Windows. (S13, S14)

When booting Windows, the CPU prompts you to enter your ID and password (ie, to log on to the family), and when the user enters your ID and password, the computer's working environment corresponds to the Windows environment that corresponds to the ID and password. Set.

On the other hand, such a family log-on function is a convenient feature that allows a large number of users to set up a Windows environment that suits their tastes through a single PC, but may cause inconvenience to beginners who do not handle computers well. There is a problem.

The technical problem to be solved by the present invention is to solve such a problem, as well as to provide a computer system that can be used by a large number of users as a working environment for each user, as well as easy to use even a computer novice. It is to. The invention is also intended to facilitate the selection and switching of working modes.

A computer system according to one aspect of the present invention for achieving the above object is

Here, the driving method of the computer system of the present invention

A fourth step of determining whether the first power button or the second power button is selected while the computer is driven in the first work mode or the second work mode; If the power button selected in the fourth step is the same as the previously selected power button, the computer system is turned off. If the power button is different from the previously selected power button, the program executed in the previous work mode is terminated. The method may further include a fifth step of switching to a work mode corresponding to the selected power button.

Here, the first working mode and the second working mode may be first and second operating systems, respectively. In addition, the first working mode is a learning mode for setting a computer system in a preset window environment for beginners, and the second working mode requires each user to input an ID and password to correspond to the input ID and password. It can also be a normal mode of setting up a computer system in a Windows environment.

At this time, the third step is

In addition, when the user presses the second power button 42 to start the computer system while the computer system is off, the computer system is driven in the normal mode. That is, the computer system requires input of a user's ID and password, and drives the computer to a predetermined window environment in accordance with the ID and password.

On the other hand, when the button that started the computer is pressed again in this state, for example, when the first power button 41 is pressed again in the state of driving in the learning mode, the computer system is terminated, but the other button, that is, the second power button 42 Press to switch to normal mode. That is, when the second power button 42 is pressed while the computer system is running in the learning mode, the program that is running is terminated, logged off, and the family is logged on again to change the window environment. Let's do it.

3 is a diagram showing the configuration of a computer system according to the first embodiment of the present invention.

As shown in FIG. 3, the computer system according to the first embodiment of the present invention includes a CPU 30, a bus 40, a RAM 50, a ROM 60, an RTC 70, and a user interface 80. And a serial / parallel peripheral unit 90, an auxiliary memory device driving unit 100, a user interface controller 110, a serial / parallel port unit 120, an auxiliary memory device driving control unit 130, and a button detector 160.

In FIG. 3, the CPU 30 controls the overall operation of the computer system, and the bus 40 interconnects each element constituting the system and transfers information between each element.

Random access memory (RAM) 50 temporarily stores user software and system software performed by the CPU 30, and read only memory (ROM) 60 is a system initialization program executed by the CPU, that is, a BIOS program. Is saving. The real time clock (RTC) 70 stores information about time calculation and system configuration.

The user interface unit 80 includes a display device 82 and a keyboard 84, and the serial / parallel peripheral unit 90 includes an RS-232C interface device 92 and a printer 94.

The button detector 160 detects which button of the power buttons 41 and 42 of FIG. 2 is selected, and transmits the detection result to the CPU 30 through the bus 40.

Next, the operation of the computer system according to the first embodiment of the present invention will be described with reference to FIGS.

4 is a diagram showing the operation of the computer system according to the first embodiment of the present invention.

As shown in Fig. 4, when one of the first power button 41 and the second power button 42 is pressed while the computer system is off, power is applied to the computer system. (S100)

When power is supplied to the computer system, the CPU 30 of the computer system initializes the system so that hardware such as the display controller 112 and the keyboard controller 114 can operate by a BIOS program in the ROM 60. Perform POST process to check for abnormalities. (S110)

After the POST process is performed, the CPU 30 determines which button is selected according to the detection result from the button detector 160, and then sets a BIOS flag corresponding to the selected button. (S120) Then, after loading and executing IO.SYS and MSDOS.SYS in RAM 50 at a specific location on the hard disk or floppy disk by the startup program in the BIOS program (S130), the CONFIG.SYS file Run (S140)

The CPU 30 calls the BIOS function, reads the flag value set in step S120, and determines whether the learning mode or the normal mode is set according to the flag value, and sets the registry. (S150, S160)

Then, boot the window (S170), and performs the Windows family log on function. (S170, S180)

In this case, when the user selects the learning mode by pressing the first power button, the window environment is set to the already set window environment without displaying the content for the window family log on, that is, the ID and password input on the display device. If the normal mode is selected by pressing the second button, contents for inputting an ID and a password are displayed on the display apparatus. Then, the user enters his ID and password through the keyboard, and the computer system is set to a window environment corresponding to the entered ID and password. (S190)

On the other hand, pressing the same button as the button that started the computer in this state ends the computer system, and pressing another button switches to another mode. Specifically, for example, when the second power button 42 is pressed while the computer system is driven in the learning mode by pressing the first power button, the program being executed is terminated and logged off, and then the family log on is induced again. Change the environment. In addition, when the first power button 41 is pressed while the computer system is driven in the normal mode by pressing the second power button, the program being executed is terminated and logged off, and then the computer is set to the window environment already set according to the learning mode. Set up your system.

As described above, according to the first embodiment of the present invention, after the first and second power buttons are installed in the main body of the computer, one of the two buttons can be pressed to set the learning mode or the normal mode. Therefore, if you are a beginner of the computer, you can set the computer system to the already set window environment by pressing the first power button to select the learning mode, and in the case of multiple users, the general mode can be set by pressing the second power button. You can set the working environment to your liking.

In addition, after setting the window environment to the normal mode or the learning mode, it is easy to switch to another mode by pressing the power button.

In the first embodiment of the present invention, the window environment setting and the mode switching in the learning mode or the normal mode have been described, but the present invention can be used for setting and changing the OS in addition, and this is described as the second embodiment of the present invention. .

The appearance of the computer system and the configuration of the computer system according to the second embodiment of the present invention are the same as those in Figs. Accordingly, hereinafter, redundant descriptions of the computer system will be omitted and the operation according to the second embodiment of the present invention will be described with reference to FIG. 5.

5 is a flowchart illustrating the operation of the computer system according to the second embodiment of the present invention.

First, when a user applies power to the computer system by selecting one of the first and second power buttons 41 and 42 (S300), the CPU 30 may enter into a BIOS program stored in the ROM 60. By doing so, the system is initialized so that hardware such as the display controller 112 and the keyboard controller 114 can operate, and a power on self test (POST) process is performed to check whether each hardware is abnormal. (S310)

Then, the CPU 30 determines which button is selected according to the detection result from the button detector 160. (S320)

As a result of the determination in the above step, when it is determined that the first power button 41 is selected, the CPU 30 uses the bootstrap loader included in the BIOS program to determine the first of the hard disk or the floppy disk. After loading the first boot program mounted at the location into the RAM 50, the first boot program is executed. The first boot program loads a previously stored first OS into a RAM, and the first OS performs an OS initialization process at a computer system level and then enters a standby state for receiving a command input.

In the standby state, a user enters a command to execute a necessary task by executing an application under the first OS. (S340)

On the other hand, when it is determined in step S320 that the second button 42 is selected, the CPU is mounted at a second position of a hard disk or a floppy disk by a bootstrap loader included in a BIOS program. After loading the second boot program into the RAM 50, the second boot program is executed. In operation S350, the second boot program loads the already stored second OS into the RAM, and the second OS performs an OS initialization process at a computer system level and then enters a standby state for receiving a command input.

In the standby state, the user enters a command to execute a necessary task by executing an application program under the second OS. (S360)

During the above steps S340 and ST360, the user presses the power button for the purpose of turning off the system or changing the OS. (S370)

Then, the CPU 30 determines whether the same button as the selected button is selected in step S300 according to the detection result from the button detector 160. (S380)

As a result of the above determination, when the same button as the previously selected button is selected, the CPU determines that the user wants to shut down the system and performs a series of processes for turning off the computer system. (S390)

On the other hand, if a button that is not the same as the button selected before the step is selected as the result of the step, the CPU determines that the user wants to change the OS currently used, and first performs the operation under the current OS. After exiting, switch jobs to another OS system. (S400)

As described above, according to the second embodiment of the present invention, the computer system can be started by the first OS or the second OS by selecting one of the two buttons, and the operation is performed under the first OS (or the second OS). Even when performing, the operation can be easily switched to another OS by selecting the second button (or the first button).

In the first and second embodiments described above, only two power buttons have been described as an example, but more buttons may be used. In addition, in the second embodiment of the present invention, two buttons are used to turn on / off the power and change the window environment or the OS. However, the button and the OS or the window environment that perform the functions of turning on / off the power are changed. Independently provide a button to perform the.

As described above, according to the present invention, it is possible to select a required work mode by selecting one button among a plurality of buttons, and to easily change the work mode.
