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.
Description
Technical field
The present invention relates to computer server development technique field, specifically the update method of a kind of mainboard VR.
Background technology
Digital integrated circuit components and parts and line is integrated in DLC (digital logic circuit) or system that same semi-conductor chip is made.According to the gate circuit comprised in digital integrated circuit or unit, number of devices, digital integrated circuit can be divided into integrated (SSI) circuit, medium-scale integration MSI circuit, large-scale integrated (LSI) circuit, ultra-large integrated VLSI circuit and imperial scale integrated (ULSI) circuit on a small scale.
Along with the develop rapidly of computer technology and integrated circuit technique, VR chip on all kinds of server master board all adopts digit chip, and can be carried out the rewriting of VR formula by I2C link, object is the optimization realizing mainboard VR, thus ensure that main board power supply is stablized, power consumption optimum.Generally, the renewal of VR code can complete burning by under line, or utilizes DOS formula to complete renewal, but all can increase operation steps extra in production run, also easily produces and leaks brush problem, can not ensure the consistance of mainboard.
Summary of the invention
Technical assignment of the present invention is the optimization to prior art, provides the update method of a kind of practical mainboard VR.
The update method of a kind of mainboard VR of the present invention, be the startup of the renewal of VR with BIOS completed, the upgrading frequency of mainboard BIOS is far longer than the upgrading of VR code, if so there is the VR formula of new edition to need upgrading, BIOS can be utilized to have come.The inventive method is simple and convenient, effectively enhances productivity, and coordinates the startup of BIOS to complete upgrading simultaneously and upgrades, the effective guarantee consistance of mainboard.
This method completes batch upgrade with the batch upgrade of BIOS, effectively enhances productivity, coordinate BIOS start-up course to realize simultaneously, the effective guarantee consistance of mainboard.
Technical scheme of the present invention realizes in the following manner,
A update method of mainboard VR, its specific implementation process is:
Formula of being upgraded by VR is embedded in BIOS, in BIOS start-up course, by I2C link operation, completes the upgrading of VR version.
The update method of described a kind of mainboard VR, it is in BIOS start-up course, can pass through the current VR of I2C interface accessing, if VR version is lower than the version embedded in BIOS, then implement update action by I2C read write command, after BIOS has started, VR version also upgrades.
The update method of described a kind of mainboard VR, formula of being upgraded by VR described in it is embedded into BIOS, namely the part of VR file as BIOS, one piece is compressed to bios code, in BIOS implementation, decompression VR formula, and VR program statement by I2C command operation write VR chip.
The beneficial effect that the present invention is compared with prior art produced is:
VR formula only need embed in BIOS by the update method of a kind of mainboard VR of the present invention, utilize the start-up course of BIOS, the renewal of batch VR formula can be realized, method is simply efficient, automatically can complete version contrast, improve production efficiency, ensure mainboard consistance, practical, applied widely, be easy to promote.
Without any need for hardware device, effectively reduce the step that VR upgrades separately, improve production efficiency, reduce the risk that VR leaks brush.
Accompanying drawing explanation
Accompanying drawing 1 is realization flow figure of the present invention.
Embodiment
More detailed elaboration is carried out to content of the present invention below:
Be described in detail below below in conjunction with the update method of accompanying drawing to a kind of mainboard VR of the present invention.
The invention provides the update method of a kind of mainboard VR, as shown in Figure 1, its specific implementation process is:
By needing the VR file upgraded to be embedded in bios code, in BIOS start-up course, the current VR of I2C interface accessing can be passed through, if VR version is lower than the version embedded in BIOS, then implement update action by I2C read write command, after BIOS has started, VR version also upgrades.
The update method of described a kind of mainboard VR, it is characterized in that: described formula of being upgraded by VR is embedded into BIOS, namely the part of VR file as BIOS, one piece is compressed to bios code, in BIOS implementation, decompression VR formula, and VR program statement by I2C command operation write VR chip.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
