Description

Method for automatically repairing system configuration by single key control

Technical Field

The present invention relates to a method for updating/recovering a system configuration, and more particularly, to a method for updating/recovering a system configuration by single key control.

Background

The Basic Input Output System (BIOS) is a software program code stored in a chip and loaded/executed when a computer is turned on. The BIOS provides a Power On Self Test (POST) program required for booting the computer, checks whether the operating states of a Central Processing Unit (CPU) and each controller or buffer of the computer are normal, and provides the computer system with initialization operations for a memory, a motherboard chip, a display card, and various peripheral devices, the initialization operations including creating an interrupt vector, setting a buffer, initializing and detecting system hardware devices, and providing various resident programs for an operating system or an application program to call. With the increasing demand of users for computers, peripheral equipment such as a CPU (central processing unit), a memory, a display card and the like of computer hardware are continuously replaced, and the working efficiency of the computers is improved by high-efficiency hardware. In addition, the work efficiency of the computer can be improved by updating the BIOS (program) and modifying the parameters for controlling the operation frequency of the computer hardware in the BIOS.

Some updating methods are to remove the BIOS chip from the motherboard and update/write a new BIOS or set operating parameters by a specific machine. The updating method is time-consuming and labor-consuming, the BIOS chip is removed from the motherboard with effort by opening the casing, and the motherboard is reinstalled after the BIOS is updated, so that the probability of damaging pins of the BIOS chip is increased in the processes of disassembling and installing the BIOS chip. With the advent of Electrically erasable programmable Read-Only Memory (EEP ROM), an update operation can be performed without the need to take effort to detach the BIOS chip, however, if the system cannot be booted or is booted unstably due to excessive frequency and excessive voltage errors, and the original setting value needs to be recovered, the user still needs to open the casing and adjust the CMOS clear Jumper (Jumper) to clear the wrong CMOS data, so as to set the relevant default value. It is inconvenient for the user and the steps are still cumbersome.

Disclosure of Invention

In view of the above problems of complicated steps and inconvenient operation of BIOS update/recovery, the present invention provides a method for automatically repairing system configuration by single key control, which executes corresponding maintenance items for BIOS by different pressing operation modes of a power-on key, so as to solve the defects of complicated steps and inconvenience of BIOS system update/recovery, and facilitate maintenance of a computer system.

To achieve the above object, the method for single key control automatic repair system configuration of the present invention comprises the following steps: first, the pressing mode of the power-on key is detected. Then, the repair item represented by the pressing pattern is determined. And then, executing the corresponding program for repairing the BIOS according to the repairing item. And executing a normal boot process after executing the corresponding program for repairing the system configuration of the BIOS.

In the method for configuring an automatic single-button-controlled repair system according to a preferred embodiment of the present invention, the pressing mode includes: the pressing mode of the machine key is judged according to the combination of the number of times of pressing the machine key, the time of pressing the machine key each time and the pressing mode consisting of the pressing number, the pressing time and the interval time of pressing twice.

Detailed Description

The method for automatically repairing the system configuration by single key control (hereinafter, briefly described as the method) is executed by a repairing function control chip embedded in a mainboard. In the preferred embodiment, the BIOS configuration is used to update/recover the BIOS program, or update/recover the BIOS system configuration, and the BIOS related system configuration recorded in the CMOS memory is cleared. When a user updates a BIOS (program) or changes the working frequency (over-frequency and over-voltage) of a mainboard, if the program update or the mainboard setting modification fails, the system is unstable or the system cannot be started, and at the moment, the BIOS chip is not required to be pulled out by disassembling the shell with great expense by executing the invention, and the computer system is not required to be recovered through complicated BIOS updating steps. FIG. 1 is a flow chart of a method for configuring an automatic single-key-controlled repair system. Referring to fig. 1, in a preferred embodiment, the method includes the following steps: first, detecting a pressing mode of a power-on key (step S110); next, determining a repair item represented by the pressing mode (step S120); then, executing the corresponding program of the repair system configuration according to the repair item (step S130); and, executing the normal boot process (step S140).

FIG. 2 is a system diagram illustrating a method for performing a single key controlled automatic repair system configuration. In this embodiment, the system for executing the method includes a host computer composed of a motherboard 200, a central processing unit 210, a memory 220, a hard disk 230, a floppy disk 240, and an optical disk 250. In addition, the motherboard is further embedded with a timing/counting circuit 202, a COMS memory 203, a jumper controller 204, a repair function control chip 205, and a BIOS chip 206. The BIOS main program is stored in the BIOS chip 206, and when the start key 201 is pressed to perform a normal start program, the BIOS chip 206 reads the BIOS main program and loads the memory 220 to execute the program. Compared with the conventional BIOS system, the difference of the present invention is that before the motherboard leaves the factory, the corresponding relationship between the pressing mode of the power-on key 201 and the repair items is established in the repair function control chip 205, and the program of the repair system configuration (especially the system configuration of the BIOS system) that needs to be executed by the repair items is recorded.

The pressing mode is a combination of the number of times the user presses the start key 201 and the pressing time, and for example, the user continuously presses the start key 201 for several seconds and then continuously presses the start key 201 three times, which is a pressing mode. Through the timer/counter circuit 202, the pressing times and pressing time of the power-on key 201 can be detected, and the pressing mode can be determined accordingly. The timing/counting circuit 202 may be constituted by an oscillator and a simple arithmetic chip embedded in the motherboard, one end of the timing/counting circuit 202 is connected to the power-on key 201, and the other end is connected to the repair function control chip 205, and by accumulating the circuit conduction times and the circuit conduction time of the power-on key 201, the aforementioned pressing times and pressing time of the power-on key 201 can be calculated, and the detected pressing mode is transmitted to the repair function control chip 205.

In the preferred embodiment, the pressing mode, the corresponding repair items, and the repair system configuration are programmed as follows:

when the pressing mode is long pressing the power-on key 201 for three seconds, the power-on key 201 is pressed once again, and the configuration data of the CMOS memory system is cleared. The procedure for clearing the CMOS memory system configuration data comprises the following steps: the repair function control chip 205 transmits a data clear signal to the jumper controller 204, and then transmits a control voltage to disconnect the data save pin of the CMOS memory and enable the data clear pin to clear the setting of the BIOS-related system configuration stored in the CMOS memory by the jumper controller 204.

When the pressing mode is long pressing the power-on key 201 for three seconds, the power-on key 201 is pressed twice, and the system configuration setting for restoring the original BIOS is performed. The procedure for recovering the original BIOS system configuration includes first fetching the BIOS parameters from the storage locations storing the original BIOS parameters (i.e., the BIOS configuration), where the storage locations may be storage spaces in the BIOS chip 206, or storage spaces in the memory 220, the hard disk 230, the floppy disk 240, or even the optical disk 250, and the scope of the storage spaces is not limited herein. After the original BIOS system configuration parameters are taken out, the original BIOS system configuration parameters are covered with the current BIOS system configuration parameters, and then the computer is restarted, so that the original system configuration setting can be restored.

When the pressing mode is that the start key 201 is pressed for three seconds and then the start key 201 is pressed for three times, the BIOS program is overwritten. The action of overwriting the BIOS program comprises capturing the original BIOS program from the storage position, and then overwriting the currently used BIOS program with the original BIOS program (i.e. overwriting the original BIOS program in the position where the currently used BIOS program is stored). And when the coverage is finished, restarting the computer, wherein the loaded BIOS program is the original BIOS program. For a motherboard supporting dual BIOS, there are usually two BIOS programs. When the BIOS program in use is damaged, only the original BIOS program needs to be covered. However, for some motherboards that do not support dual BIOS, when the computer is first started, the BIOS program can be backed up to any of the aforementioned storage locations to save the original BIOS program.

When the computer can not be normally started, the user presses the start-up key 201 for three seconds, and then presses the start-up key 201 once again, so that the system configuration action carried by the CMOS memory can be cleared; similarly, after the user presses the power-on key 201 for three seconds, the user presses the power-on key 201 for three times, and then the BIOS program is overwritten. If the pressing mode of the power-on key 201 is not within the preset range (i.e. the repair item represented by the pressing mode cannot be determined), the normal power-on process is directly executed. In addition, the procedure for clearing the CMOS memory data is performed when the computer is in a shutdown state; the recovery of the original BIOS parameter setting and the BIOS program overwriting can be executed in the computer boot state.

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 the jumper controller 204 connected to the CMOS memory 203. Referring to fig. 3, in the present embodiment, a BJT transistor 307 is used to connect a data save pin 308 and a data clear pin 309 of the CMOS memory 203. At normal power-on, the jumper controller 204 transmits a forward bias voltage to turn on the data save pin 308, and the data clear pin 309 is connected to the jumper controller 204 but is not electrically connected. When the jumper controller 204 transmits a reverse bias, the data save pin 308 is open, and the data clear pin 309 is electrically connected (i.e., 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 the present embodiment, the BJT transistor 307 is used to enable the data clear pin 309 by a control voltage (forward/reverse bias), so that the data in the CMOS memory 203 can be released without disassembling the chassis. However, this is only one embodiment, and it is also within the scope of the present invention that other components release the data of the CMOS memory 203 by controlling the voltage enable data clear pin 309.

In summary, the present invention automatically executes the corresponding BIOS update/recovery procedure by pressing the power-on key, and has the following advantages:

the BIOS system configuration or the BIOS system main program of the computer can be updated only by pressing a single key without complicated setting steps.

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