Abstract

The invention provides a CPU power-on time sequence control method, device and system. The method includes the steps that S0, a signal output device is pre-arranged; S1, after an external server is switched on, a CPU power-off instruction is sent to the signal output device; S2, a first control signal is sent to an external server CPU by utilizing the signal output device according to the received CPU power-off instruction, so that the CPU is not powered on; S3, whether a basic input / output system program of the external server is tampered or not is detected; S4, when the basic input / output system program of the external server is not tampered, the CPU power-off instruction is sent to the signal output device; S5, a second control signal is sent to the external server CPU by utilizing the signal output device according to the received CPU power-off instruction, so that the CPU is powered on. By the adoption of the technical scheme, the security of the server can be improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, and in particular, to a method, device and system for CPU power-on sequence control. Background technique [0002] With the continuous development of computer application technology, the security of the server has also attracted people's attention. [0003] At present, in order to improve the security of the server, it is usually necessary to configure a special BMC (Baseboard Management Controller) for the server to monitor the physical characteristics of some components in the server under the current working state in real time, such as fan speed, CPU (Central Processing Unit, central processing unit) input voltage, working temperature, whether the basic input and output system program has changed, etc., so that the staff can manage the server accordingly according to the monitoring results. [0004] It can be seen that in the above technical solution, the BMC cannot con...
