Problems solved by technology

However, the process of AC power-off and power-on of the Intel motherboard will generate a certain amount of time overhead, so the efficiency of firmware update for Intel ME is relatively low, and the power-on process of the Intel motherboard from the power-off state to the normal state , unable to provide normal services to the outside world, which in turn will relatively reduce the work efficiency of the Intel motherboard

Embodiment 1

[0040] figure 1 It is a flow chart of an Intel ME firmware update method provided by an embodiment of the present invention. Please refer to figure 1 , the specific steps of the firmware update method of Intel ME include:

[0041] Step S10: triggering a system management interrupt of the Intel mainboard in the form of BIOS, and updating the IntelME through preset firmware.

[0042] It should be noted that the BIOS is a basic input and output system in every computer. It is a set of programs solidified in a read-only memory chip on the motherboard of the computer, which stores the most important basic input and output of the computer. Programs, self-test programs after power-on and system self-starting programs, the main function of which is to provide the lowest-level, most direct hardware settings and controls for the computer. Therefore, when updating the Intel ME of an Intel motherboard, specific control needs to be carried out through the BIOS. In order to ensure the sm...

Embodiment 2

[0048] figure 2 It is a flow chart of another Intel ME firmware update method provided by the embodiment of the present invention. figure 2 In steps S10 and S12 and figure 1 Same, no more details here.

[0049] Such as figure 2 As shown, as a preferred embodiment, before judging whether the update to Intel ME is completed, the method further includes:

[0050] Step S20: Set the flag bit with an initial value, and assign a corresponding state value to the flag bit according to the update status of the Intel ME.

[0051] Correspondingly, step S11 is specifically:

[0052] Step S21: Judging whether the update of the Intel ME is completed according to the current state value of the flag bit.

[0053] It should be noted that since it is necessary to ensure that the GlobalReset method is called to reset Intel ME globally after the update of Intel ME is completed, it is necessary to pay attention to whether its update status changes in real time when Intel ME is updated, so t...

Embodiment 3

[0066] The embodiment of the firmware update method of Intel ME has been described in detail above, and the present invention also provides a kind of firmware update device of Intel ME corresponding to the method, because the embodiment of the device part and the embodiment of the method part are mutually Correspondingly, for the embodiment of the device part, please refer to the description of the embodiment of the method part, and details will not be repeated here.

[0067] image 3 A structural diagram of an Intel ME firmware update device provided by an embodiment of the present invention. The firmware update device of the Intel ME that the embodiment of the present invention provides specifically includes:

[0068] The update module 10 is used to trigger the system management interrupt of the Intel motherboard in the form of BIOS, and update the Intel ME through preset firmware.

[0069] The judging module 11 is used for judging whether the update of the Intel ME is com...

Abstract

The invention discloses a firmware updating method and device for Intel ME and a medium. The method comprises the steps of triggering system management interruption of an Intel mainboard in BIOS (basic input / output system) manner, and updating the Intel ME through preset firmware; judging whether updating of the Intel ME is compete; if yes, calling a GlobalReset process inherent in the Intel mainboard to globally reset the Intel ME so that the Intel ME takes effect. The method has the advantages that updating time overhead is relatively reduced, firmware updating efficiency is improved, and overall working efficiency of a mainboard during firmware updating is guaranteed. In addition, the invention also provides a firmware updating device for Intel ME and a medium, which have the above advantages.

Description

technical field [0001] The invention relates to the field of firmware update, in particular to an Intel ME firmware update method, device and medium. Background technique [0002] Nowadays, computer hardware and software technologies are advancing rapidly, and hardware and software updates and upgrades have become normalized. [0003] On the Intel platform, updating the motherboard BIOS may also involve updating the Intel ME firmware. The current update method is to control the AC power off of the Intel motherboard after upgrading the firmware of Intel ME, so that the registers on the Intel motherboard can be restored to the original state, and then power on the Intel motherboard again, so that the upgraded Intel ME takes effect. However, the process of AC power-off and power-on of the Intel motherboard will generate a certain amount of time overhead, so the efficiency of firmware update for Intel ME is relatively low, and the power-on process of the Intel motherboard from...
