Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a BIOS hot standby restoration method, device, equipment and storage medium. Background Art

[0002] BIOS (Base Input / Output System) is a startup program embedded in the computer motherboard memory chip. It includes chip initialization, power-on self-test, boot file boot, and saves user settings. It provides the most basic hardware control for computer devices and transmits device information to the system layer. The normal operation of BIOS is the prerequisite for the startup of the computer system and has a vital impact on the reliability and stability of computer devices.

[0003] Traditional methods generally use a single flash memory chip to store the BIOS program, and there is no backup of the BIOS program. Once an abnormality occurs in the BIOS program in the flash memory chip, the computer device will not be able to start and run normally. In the prior art, in order to improve reliability, one method is to store the BIOS program backup to different addresses of the same flash memory chip. When an abnormality occurs in the operation of the main BIOS program, the computer can jump to the starting address, call the backup BIOS program stored in the flash memory chip, and use the backup BIOS program to start the computer device. Another method is to use two flash memory chips A and B to store the BIOS program. When an abnormality occurs in the operation of the BIOS program in the A flash memory chip, the computer can switch to the B flash memory chip and call the BIOS program stored in the B flash memory chip to start the computer device.

[0004] The existing technical solution can avoid the problem of being unable to boot due to damage of flash memory chip A, but the flash memory chips A and B store the same BIOS program. When the user modifies the BIOS configuration during the boot process, such as the boot password, boot sequence, etc., and saves it to the flash memory chip A, the data cannot be synchronized to the flash memory chip B. If the flash memory chip A is damaged and the flash memory chip B is used for booting, the user's modified content will be completely lost, causing serious accidents and affecting computer security.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application. Summary of the invention

The method according to claim 1, characterized in that The method of writing the read main BIOS program into the standby BIOS chip through the SPI interface based on the BIOS error flag bit, so as to implement hot standby of user data of the standby BIOS chip through the main BIOS program, comprises: The system application under the operating system reads the BIOS error flag bit, and if the BIOS error flag bit exists, the application reads the BIOS program from the backup BIOS chip; The system application notifies the MCU to switch the chip select switch to the main BIOS chip and clear the BIOS error flag; The system application writes the read backup BIOS program into the main BIOS chip through the SPI interface, so as to implement the main BIOS chip program recovery through the backup BIOS program.

3. The method according to claim 2, characterized in that The method further comprises: If the BIOS error flag does not exist, the system application reads the BIOS program from the main BIOS chip; The system application notifies the MCU to switch the chip select switch to the backup BIOS chip; The system application writes the read main BIOS program into the standby BIOS chip through the SPI interface, so as to implement hot standby of user data of the standby BIOS chip through the main BIOS program; After the user data hot backup is completed, the system application notifies the MCU to switch the chip select switch to the main BIOS chip.

4. The method according to claim 1, characterized in that: The method further comprises: Control the computer equipment to start up and power on, and start the equipment from the main BIOS chip through CPLD control.

5. A BIOS hot standby restoration device, characterized in that: The device comprises: The status monitoring module is used to monitor the serial port startup information of the main BIOS chip through the MCU to determine whether the main BIOS chip program is executed normally; if the main BIOS chip program fails to start, the MCU switches the chip select switch to the standby BIOS chip, sets the BIOS error flag, and sends a restart signal to the CPLD; the CPLD receives the restart signal, re-powers on the control device to restart, and starts from the standby BIOS chip to enter the system; A data reading module, used for writing the read main BIOS program into the standby BIOS chip through the SPI interface based on the BIOS error flag bit; The program hot standby module is used to obtain the BIOS program from the main / standby BIOS chip through the system application, and write the BIOS backup program into the main and standby BIOS chips according to the error flag bit situation, so as to realize the main BIOS chip program recovery and standby BIOS chip user data hot standby through the BIOS backup program.

6. The device according to claim 5, characterized in that The method of writing the read main BIOS program into the standby BIOS chip through the SPI interface based on the BIOS error flag bit includes: The system application under the operating system reads the BIOS error flag bit, and if the BIOS error flag bit exists, the application reads the BIOS program from the backup BIOS chip; The system application notifies the MCU to switch the chip select switch to the main BIOS chip and clear the BIOS error flag; The system application writes the read backup BIOS program into the main BIOS chip through the SPI interface, so as to implement the main BIOS chip program recovery through the backup BIOS program.

7. The device according to claim 6, characterized in that If the BIOS error flag does not exist, the system application reads the BIOS program from the main BIOS chip; The system application notifies the MCU to switch the chip select switch to the backup BIOS chip; The system application writes the read main BIOS program into the standby BIOS chip through the SPI interface, so as to implement hot standby of user data of the standby BIOS chip through the main BIOS program; After the user data hot backup is completed, the system application notifies the MCU to switch the chip select switch to the main BIOS chip.

8. The device according to claim 5, characterized in that The device also includes a power control module; The power control module is used to control the computer device to start up and power on, and to start the device from the main BIOS chip through the CPLD control device.

9. An electronic device, characterized in that: include: at least one processor; and a memory communicatively coupled to the at least one processor; It is characterized in that the memory stores instructions that can be executed by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the BIOS hot standby restoration method described in any one of claims 1-4.

10. A storage medium storing program instructions, characterized in that: When the program instructions are run, the BIOS hot standby restoration method according to any one of claims 1 to 4 is executed.
