Description
Technical Field
The invention relates to the technical field of computers, in particular to a computer mainboard chip security management method, a device and computer equipment.
Background
In the related art, a BIOS (Basic Input Output System, main board) is widely used in the computer industry, and is an indispensable part of almost all computers. The motherboard is mainly responsible for actions related to computer booting, including but not limited to computer power-on self-test, memory, Central Processing Unit (CPU), initialization of each hardware and booting of computer operating system, etc. The motherboard chip, i.e., the chip in the motherboard, also stores some configurations and parameters important to the computer user, such as over-frequency voltage configuration, administrator password, or user password. These configurations have the extremely important and somewhat inadvertent impact on the security of the computer, which can have the consequence of not having to open the computer, or even damage the hardware.
At present, the security management measures for computer motherboard chips are less, most chips are welded on the motherboard and are not easy to take off, and the motherboard chips adopt NOR Flash (non-volatile Flash technology) technology, so that data in the motherboard chips cannot be lost accidentally.
At present, the known technology of dual BIOS (i.e. two motherboard chips are designed on a motherboard) for protecting motherboard chip data is different in the specific implementation schemes corresponding to different manufacturers, but the basic principles are the same: when the main mainboard is damaged and cannot start the computer, another mainboard is started to finish starting the computer, and then the damaged main mainboard is repaired. Thus, the purpose of normally using the computer is achieved.
In the prior art, the attention degree of data inside a mainboard chip is not enough, and all contents in the mainboard chip can be read out only by taking a computer and taking the mainboard chip down by using a soldering iron and the like and then checking the model of the chip by using a burner; then, by using the principle of writing data by blocks during compiling, the personalized configuration parameters and the places where the passwords are stored of the computer users can be found. Although the read data is in binary form, the required data, such as the very critical motherboard password, can still be deduced reversely by mainstream decoding. This is a potential safety hazard that can be amplified especially on computer servers that store large amounts of important data. The computer server mostly stores data information which companies rely on for survival, and generally has password protection, and a mainboard password after the computer startup initialization is the first safety protection program. If someone takes out the motherboard chip read data by using the hidden trouble at this time, the motherboard password is analyzed, and the computer is successfully started, which is disadvantageous to the data security of the computer. However, the conventional technology cannot detect whether the motherboard chip has been removed or not in a computer shutdown state.
