Computer boot method, controller, storage medium, and system

A computer boot method, wherein the method is applied to a controller, the controller comprises a security check kernel, and the security check kernel communicates with a control switch through an enable control pin of the control switch, the control switch is connected to the security check kernel through a first channel, the control switch is connected to a computer hardware system through a second channel, the control switch is connected to a BIOS file storage apparatus through a third channel, and the control switch includes an initial state and an actuated state, the initial state with the security check kernel connected to the BIOS file storage apparatus and the computer hardware system disconnected from the BIOS file storage apparatus and the actuated state with the security check kernel disconnected from the BIOs file storage apparatus and the computer hardware system connected to the BIOS file storage apparatus, and the computer boot method comprises:

• obtaining, by the security check kernel, a first boot program file that is a BIOS file pre-stored in the BIOS file storage apparatus through the first channel and the third channel with the control switch in the initial state;
• checking, by the security check kernel, the first boot program file;
• sending, by the security check kernel, a first instruction to the control switch through the enable control pin to change the control switch from the initial state to the actuated state when the first boot program file is successfully checked;
• and
• receiving, by the control switch, the first instruction through the enable control pin, and connecting, by the control switch changing from the initial state to the actuated state, the second channel to the third channel according to the first instruction establishing a connection between the BIOS file storage apparatus and the computer hardware system when the second channel is connected to the third channel causing the computer hardware system to complete power-on and running using the first boot program file.

A controller, comprising:

• a security check kernel communicatively coupled to a control switch;
• connected to a computer hardware system and connected to a BIOS file storage apparatus, the control switch comprising an initial state and an actuated state, wherein in the initial state the security check kernel is connected to the BIOS file storage apparatus and the computer hardware system is disconnected from the BIOS file storage apparatus and in the actuated state the security check kernel is disconnected from the BIOS file storage apparatus and the computer hardware system is connected to the BIOS file storage apparatus;
• a memory configured to store instructions for the security check kernel;
• and
• a processor, communicatively coupled with the memory, configured to execute the instructions in the memory, to perform operations that comprise:
• obtaining a first boot program file that is a BIOS filed pre-stored in the BIOS file storage apparatus when the controller is powered on and runs with the control switch in the initial state,
• checking the first boot program file, and
• establishing, by changing the control switch from the initial state to the actuated state, a connection between the BIOS file storage apparatus and the computer hardware system when the first boot program file is successfully checked the computer hardware system completes power-on and running using the first boot program file when the connection between the BIOS file storage apparatus and the computer hardware system is successfully established.

A controller, comprising:

• a control switch connected to a security check kernel through a first channel, the control switch connected to a computer hardware system through a second channel, and the control switch connected to a BIOS file storage apparatus through a third channel, wherein the control switch has an initial state and an actuated state and comprises an enable control pin through which the control switch and the security check kernel communicate to change the control switch from the initial state and the actuated state, the initial state with the security check kernel connected to the BIOS file storage apparatus and the computer hardware system disconnected from the BIOS file storage apparatus and the actuated state with the security check kernel disconnected from the BIOS file storage apparatus and the computer hardware system connected to the BIOS file storage apparatus;
• the security check kernel is configured to:
• obtain a first boot program file in the BIOS file storage apparatus through the first channel and the third channel with the control switch in the initial state, wherein the first boot program file is a BIOS file pre-stored in the BIOS file storage apparatus,
• check the first boot program file, and
• send a first instruction to the control switch through the enable control pin to change the control switch from the initial state to the actuated state when the first boot program file is successfully checked;
• and
• the control switch is configured to:
• receive the first instruction through the enable control pin,
• connect, by changing the control switch from the initial state to the actuated state, the second channel to the third channel according to the first instruction, and
• establishing, via the control switch, a connection between the BIOS file storage apparatus and the computer hardware system when the second channel is connected to the third channel causing the computer hardware system to complete power-on and running using the first boot program file.
