Example Embodiment

[0016] The content of the present invention is described in more detail below:

[0017] A method for updating a mainboard VR of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] The present invention provides a method for updating motherboard VR, as shown in the attached figure 1 As shown, the specific implementation process is:

[0019] Embed the VR file that needs to be updated into the BIOS code. During the BIOS startup process, the current VR will be accessed through the I2C interface. If the VR version is lower than the version embedded in the BIOS, the update action will be implemented through the I2C read and write commands, and the BIOS startup is complete. After that, the VR version has also been updated.

[0020] The method for updating the VR of a motherboard is characterized in that: the VR upgrade program is embedded into the BIOS, that is, the VR file is used as a part of the BIOS, and the BIOS code is

Abstract

The invention provides a main board VR renewing method, and relates to the technical field of computer server development. The specific achievement process of the method includes the steps of embedding a VR file which needs to be renewed in a BIOS code, having access to the current VR through an I2C interface in the BIOS starting process, and implementing the renewing action through the I2C reading command if the VR version is lower than the version embedded in the BIOS. After the starting of the BIOS is completed, the VR version is renewed, the independent VR renewing steps are effectively reduced, the production efficiency is improved, the VR renewing omission risk is lowered, practicability is high, and the application range is wide.
