Double BIOS control system, control method and device thereof, equipment and medium

Abstract

The invention discloses a double BIOS control system, a control method and device thereof, equipment and a medium. The double BIOS control method comprises the steps of monitoring whether a system starting module can utilize file data in a first BIOS to start a normal system or not in real time; if not, automatically triggering a low-level enable signal; transmitting the enable signal to a presetswitcher; controlling the switcher to build a communication link between the system starting module and a second BIOS through the enable signal; and reading file data in the second BIOS to the systemstarting module through the communication link, so that the system starting module utilizes the file data in the second BIOS to start the system. Labor cost caused by the fact that normal starting ofthe system can be recovered only through manual intervention in the prior art is reduced, the situation that a storage system cannot be normally started for a long time due to the fact that human neglects is avoided, and the reliability and the stability of the storage system are improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a dual BIOS control system and its control method, device, equipment and media. Background technique [0002] Usually, there is only one BIOS chip (BIOS, Basic Input Output System) on the motherboard of the existing storage system, and the user can read and write, erase or upgrade the BIOS, but this design is prone to the following problems: Once the user makes a wrong operation or is invaded by a virus, the data in the BIOS chip will be damaged, and the system cannot be started normally. [0003] For this reason, people have proposed dual BIOS design schemes for storage systems now, so that after a BIOS internal file data has a problem, the backup BIOS can be used to enable the system to start normally. Among them, the existing dual BIOS design scheme mainly includes the following types: [0004] Solution 1: Two BIOS bases are reserved on the motherboard. Under nor...

Problems solved by technology

[0002] Usually, there is only one BIOS chip (BIOS, Basic Input Output System) on the motherboard of the existing storage system, and the user can read and write, erase or upgrade the BIOS, but this design is prone to the following problems: Once the user makes a wrong operation or is invaded by a virus, the data in the BIOS chip will be damaged, and the system cannot be started normally.

[0007] However, the above-mentioned existing solutions all have the following problems: when the main BIOS chip of the storage system is abnormal, manual intervention is required to enable the system to start normally through the backup BIOS, which increases labor costs on the one hand, and on the other hand On the one hand, it is easy to cause the storage system to fail to start normally for a long time due to human neglect, which affects the reliability and stability of the storage system itself.
