Description

The Method of One-key Control and Automatic Restoration of System Configuration

technical field

The present invention relates to a method for updating/restoring system configuration, in particular to a method for updating/restoring system configuration by means of single-key control.

Background technique

The Basic Input Output System (BIOS) is a software program code stored in the chip to be loaded/executed when the computer is turned on. The BIOS provides the Power On Self Test (POST) program required for computer startup to check whether the computer's central processing unit (CPU) and various controllers or registers are operating normally, and provides a computer system for memory. , motherboard chip, display card, and various peripheral devices to perform initialization actions, these initialization actions include creating interrupt vectors, setting registers, initializing and testing system hardware devices, and providing various resident programs for operating systems or applications transfer. As users' demand for computers increases, computer hardware such as CPU, memory, display cards and other peripheral devices are also constantly replaced to improve the work efficiency of computers with high-performance hardware. In addition, updating the BIOS (program) and modifying the parameters in the BIOS to control the operating frequency of the computer hardware can also improve the working efficiency of the computer.

Some methods for updating are to remove the BIOS chip from the motherboard, and update/write new BIOS or set operating parameters through a specific machine. This update method is time-consuming and labor-intensive. It is necessary to open the case and remove the BIOS chip from the main board laboriously, and then reinstall the main board after the BIOS update is complete. The process of removing and installing the BIOS chip often increases the chance of damaging the pins of the BIOS chip. . With the emergence of Electrically Erasable Programmable Read-Only Memory (EEPROM), the BIOS chip can be updated without laborious disassembly. When booting or booting is unstable, and the original setting value needs to be restored, the user still needs to open the case and adjust the CMOS clear jumper (Jumper) to clear the wrong CMOS data and set the relevant default value. For the user, it is still inconvenient and the steps are cumbersome.

Contents of the invention

In view of the cumbersome steps and inconvenient operation of the above-mentioned BIOS update/recovery, the purpose of the present invention is to provide a single-key control method for automatically repairing the system configuration, and perform corresponding maintenance for the BIOS by means of different pressing operation modes of the power-on button Project to solve the defects of cumbersome and inconvenient steps when updating/recovering the BIOS system, and make the computer system easy to maintain.

In order to achieve the above object, the method for one-button control and automatic system configuration restoration of the present invention includes the following steps: firstly, detecting the pressing mode of the power-on button. Next, the repair item represented by the pressing pattern is judged. Then, execute the corresponding BIOS repairing program according to the repairing item. And, after executing the corresponding program for repairing the system configuration of the BIOS, execute a normal boot process.

According to the one-button control method for automatically repairing system configuration described in a preferred embodiment of the present invention, the pressing mode includes: the number of times the power button is pressed, the time of pressing the power button each time, and the number of times of pressing, the time of pressing, and The combination of pressing modes formed by the interval time between two pressings is used to determine the pressing mode of the power button. When the pressing mode of the power button is judged, the corresponding program for repairing the system configuration of the BIOS is judged.

According to the method for automatically repairing system configuration with one-key control described in a preferred embodiment of the present invention, the corresponding program for repairing the system configuration of the BIOS includes: a program for clearing CMOS memory data, restoring the original BIOS system configuration settings program, and the program overwritten by the BIOS program. If the detected pressing pattern of the power button is not the previously defined pressing pattern, which means that the repairing item represented by the detected pressing pattern and the system configuration of the BIOS cannot be distinguished, then the normal booting process is directly executed.

From the above, the single-button control automatic repair system configuration method of the present invention pre-defines the corresponding relationship between various pressing modes (that is, the way of pressing the power button) and repair items. When the power button is pressed, it judges the repair item corresponding to the pressing mode and executes the corresponding program, so that it can automatically update/restore the BIOS system or set the relevant parameters of the BIOS system without disassembling the case and taking out the BIOS chip. /maintenance, thereby making the computer system easy to maintain.

Detailed ways

The method for one-button control of the present invention to automatically repair the system configuration (hereinafter referred to as the method) is executed by the repair function control chip embedded in the motherboard. In this preferred embodiment, for example, it is used to update/restore BIOS programs, or update/restore BIOS system configuration settings, and is used to clear BIOS-related system configuration settings recorded in the CMOS memory. When the user updates the BIOS (program) or changes the operating frequency (over frequency, over voltage) of the motherboard, if the program update or modification of the motherboard settings fails, the system will often become unstable or the system cannot be turned on. By implementing the present invention, it is not necessary to dismantle the casing to extract the BIOS chip, and it is not necessary to restore the computer system through complicated BIOS updating steps. Fig. 1 is a flow chart of a method for configuring a single-key control automatic repair system. Please refer to FIG. 1, in a preferred embodiment, the method includes the following steps: first, detect the pressing pattern of the power button (step S110); then, determine the repair item represented by the pressing pattern (step S120); then, Execute the corresponding repair system configuration program according to the repair item (step S130); and execute the normal boot process (step S140).

FIG. 2 is a system schematic diagram of a method for performing single-key control automatic repair system configuration. In this embodiment, the system for executing the method includes a host computer composed of a motherboard 200 , a CPU 210 , a memory 220 , a hard disk 230 , a floppy disk 240 , and an optical disk 250 . In addition, a timer/counter circuit 202 , a COMS memory 203 , a jumper controller 204 , a repair function control chip 205 , and a BIOS chip 206 are further embedded on the motherboard. The BIOS main program is stored in the aforementioned BIOS chip 206. When the power button 201 is pressed to perform a normal boot process, the BIOS main program is read by the BIOS chip 206 and loaded into the memory 220 for execution. The difference between the present invention and the traditional BIOS system is that before the main board leaves the factory, the corresponding relationship between the pressing mode of the power button 201 and the repair items is established in the repair function control chip 205, and the repairs required to be performed by these repair items are recorded. System configuration (especially the system configuration of the BIOS system) program.

The pressing mode is actually a combination of the number of times the user presses the power button 201 and the pressing time. For example, pressing the power button 201 continuously for several seconds and then continuously pressing the power button 201 three times is a pressing mode. Through the timing/time counting circuit 202, the number of pressing times and the pressing time of the power button 201 can be detected, so as to determine the pressing mode. The timing/counting circuit 202 can be formed by an oscillator embedded in the motherboard and a simple computing chip. One end of the timing/counting circuit 202 is connected to the power button 201, and the other end is connected to the repair function control chip 205. The number of times the power button 201 is turned on and the time it lasts can be used to calculate the number of times the power button 201 was pressed and the time it was pressed, and the detected pressing pattern is sent to the repair function control chip 205 .

In this preferred embodiment, the procedure for pressing the mode and corresponding repair items and repair system configuration is as follows:

When the pressing mode is to press and hold the power button 201 for three seconds, and then press the power button 201 once, the system configuration data of the CMOS memory is cleared. The procedure for clearing the configuration data of the CMOS memory system includes: sending a data clearing signal to the jumper controller 204 with the repair function control chip 205, and then sending a control voltage through the jumper controller 204 to disconnect the data storage of the CMOS memory pin, and enable the data clear pin to clear the BIOS-related system configuration settings stored in the CMOS memory.

When the pressing mode is to press and hold the power button 201 for three seconds, then press the power button 201 twice to restore the original BIOS system configuration settings. The procedure for restoring the original BIOS system configuration settings includes first grabbing the BIOS parameters from the storage locations where the original BIOS parameters (i.e. the BIOS configuration) are stored. These storage locations can be the storage space in the BIOS chip 206 or the 220, the hard disk 230, the floppy disk 240, and even the storage space of the optical disk 250, the scope of which is not limited here. After taking out the original BIOS system configuration parameters, overwrite the current BIOS system configuration parameters with the original BIOS system configuration parameters, and then restart the computer to complete the restoration of the original system configuration settings.

When the pressing mode is to press and hold the power button 201 for three seconds, and then press the power button 201 three times, the BIOS program is overwritten. The action of overwriting the BIOS program includes grabbing the original BIOS program from the aforementioned storage location, and then covering the currently used BIOS program with the original BIOS program (that is, overwriting the original BIOS program to the location where the currently used BIOS program is stored). After overwriting is completed, restart the computer, and the BIOS program loaded at this time is the original BIOS program. Wherein, for a motherboard supporting dual BIOS, there are usually two BIOS programs. When the BIOS program in use is damaged, it only needs to overwrite the original BIOS program. However, for some motherboards that do not support dual BIOS, when the computer is started for the first time, the BIOS program can be backed up to any of the aforementioned storage locations, so as to preserve the original BIOS program.

When the computer cannot be turned on normally, the user presses the power button 201 for three seconds, and then presses the power button 201 once to clear the system configuration carried in the CMOS memory; Seconds later, when the power button 201 is pressed three times, the BIOS program is overwritten. If the pressing pattern of the power-on button 201 is not within the preset range (that is, when the repair item represented by the pressing pattern cannot be determined), the normal booting process is directly executed. In addition, the aforementioned procedure of clearing the CMOS memory data needs to be performed when the computer is turned off; and restoring the original BIOS parameter settings and overwriting the BIOS program can be executed when the computer is turned on.

The CMOS memory 203 clears the BIOS-related system configuration settings stored in the CMOS memory 203 by enabling the data clear pin 309 . FIG. 3 is a schematic diagram of connecting the jumper controller 204 to the CMOS memory 203 . Please refer to FIG. 3 , in this embodiment, for example, a BJT transistor 307 is used to connect the data saving pin 308 and the data clearing pin 309 of the CMOS memory 203 . When starting up normally, the jumper controller 204 transmits a forward bias voltage to turn on the data saving pin 308 . At this time, the data clearing pin 309 is connected to the jumper controller 204 , but is not yet electrically connected. When the jumper controller 204 transmits the reverse bias voltage, the data save pin 308 is effectively disconnected, and the data clear pin 309 is electrically connected (that is, the data clear pin 309 is enabled). When the data clear pin 309 is enabled, the BIOS-related system configuration settings stored in the CMOS memory 203 are immediately cleared. In this embodiment, the data clearing pin 309 is enabled with the control voltage (forward/reverse bias) through the BJT transistor 307, so that the data of the CMOS memory 203 can be released without dismantling the casing. However, this is only one embodiment, and releasing the data of the CMOS memory 203 by enabling the data clear pin 309 through the control voltage of other components also belongs to the scope of the present invention.

To sum up, the present invention has the following advantages by automatically executing the corresponding BIOS update/recovery program by pressing various power-on keys:

No need for cumbersome setting steps, just press a single button to update the computer's BIOS system configuration or BIOS system main program.

The BIOS program can be easily updated or the system configuration data in the CMOS memory can be cleared without dismantling the host computer.
