Problems solved by technology

[0002] The existing baseboard management controller (BMC: Baseboard Management Controller, hereinafter referred to as BMC) in the server not only collects the overall operation status and overall status information of the server, such as: system voltage, temperature, fan speed, etc., but also has heat dissipation control and Remotely control system power and other functions, so the security of the BMC firmware is particularly important. In order to prevent the BMC firmware from being burned or tampered with and loaded with malicious backdoor programs, it may cause data outflow during the operation of the BMC or cause damage to the overall server system.

Embodiment Construction

[0012] refer to figure 1 , which is an embodiment of the server system of the present invention, adopts a flash memory with a protection function for a specific internal block, allowing data writing to the specific block only when the protection function is turned off, and when the protection function is turned on, the The specific block is in a read-only protected state, and the protection function cannot be canceled through program instructions or communication during software / firmware operation. The server system includes a non-power-off erasable memory 2, a baseboard management controller 3, A remote host 4, a CPU 5, and a backup memory 6.

[0013] Cooperate with reference figure 2 , the non-power-off erasable memory 2 includes a first memory block 21 in a read-only protection state when the non-power-off erasable memory 2 is turned on for protection, and a second memory block 22, wherein the first The second memory block 22 is in a rewritable state no matter when the p...

Abstract

A server system comprises a non-power-off erase memory and a baseboard management controller, the non-power-off erase memory comprises a first memory block and a second memory block, and the first memory block is set in a read-only protection state which cannot be controlled to be cancelled through a software instruction, The first memory block and the second memory block accessed by the baseboard management controller read a verification program when the baseboard management controller starts initialization, a boot firmware is verified according to the verification program, if the verification is correct, the baseboard management controller executes the firmware to perform a subsequent initialization program of the baseboard management controller, a protection mechanism of firmware security is achieved by using less non-power-off memory erasing, so that the area occupied by an overall configuration circuit in a server system is reduced, and the hardware design cost is reduced.

Description

【Technical field】 [0001] The invention relates to an electronic digital data processing system, in particular to a server system related to the boot program of a baseboard management controller. 【Background technique】 [0002] The existing baseboard management controller (BMC: Baseboard Management Controller, hereinafter referred to as BMC) in the server not only collects the overall operation status and overall status information of the server, such as: system voltage, temperature, fan speed, etc., but also has heat dissipation control and Remotely control system power and other functions, so the security of the BMC firmware is particularly important. In order to prevent the BMC firmware from being burned or tampered with and loaded with malicious backdoor programs, it may cause data outflow during the operation of the BMC or cause damage to the overall server system. . 【Content of invention】 [0003] The technical problem to be solved by the present invention is to prov...
