A bios-based me update system and its update method

Abstract

The invention discloses a BIOS control based ME updating system and an updating method thereof. The BIOS control based ME updating system comprises a hardware design subsystem and an interface design subsystem; the hardware design subsystem comprises a BMC and a PCH; the BMC comprises a pin GPIO1 and a pin GPIO2; the PCH comprises a pin HDA_SDO and a pin RSMRST#; the pin GPIO1 is connected to the pin HDA_SDO; the pin GPIO1 and the pin HDA_SDO are connected to a standby power supply by a resistor R1; the pin GPIO2 is connected to the pin RSMRST#; and the pin GPIO2 and the pin RSMRST# are connected to the standby power supply by a resistor R3, and are grounded by using a capacitor C1. The ME updating system and the updating method of the invention have the advantages of being high in versatility, simple in operation, high in accuracy and low in cost.

Description

technical field [0001] The present invention relates to the technical field of an ME update system and its method, in particular to a BIOS-based ME update system and its update method. Background technique [0002] With the advent of the Internet era and the era of big data, people's demand for data processing and storage has shown explosive growth, and the demand for the number of servers has also increased sharply. The maintenance of this server has brought difficulties. Generally, the service life of the mainboard of the server is 3 to 5 years. In order to improve the use value and performance of the mainboard, it is inevitable to replace the new generation of CPU, which requires the simultaneous update of the firmware. In addition, the firmware itself can have bugs and needs to be updated regularly. [0003] For the sake of safety, under normal circumstances, the firmware part of the Intel Management Engine ME (Management Engine) does not allow other software to modify ...

Customers generally adopt the second method. The specific operation process is as follows: figure 1 As shown, but this brings a lot of trouble to the maintenance personnel. You have to enter the computer room to shut down, open the case, insert the jumper into the motherboard pin, and then boot into DOS, use the software to update the ME firmware. After the update is completed, remove the jumper. Restore the ME protection mechanism; in the process of inserting the jumper into the motherboard pin, there may be risks such as wrong jumper or poor contact

If there are a large number of server motherboards that need to update the ME firmware, this update method is very inefficient and has a high probability of error

In addition, motherboards of different manufacturers have different designs. Some motherboards do not need to disconnect the standby power supply. The ME upgrade can be completed by turning off and on or restarting globally, and the ME working mode can be restored; Only after the reset operation can the ME upgrade be completed and the ME working mode can be restored. If these motherboards are not reset by disconnecting the standby power supply, the ME will always be in the Recovery mode and cannot work normally.

Therefore, this requires maintenance personnel to operate the machine in the computer room and manually control the power supply, which is very troublesome, takes a lot of time, and increases the cost
