Abstract
The invention discloses a method for automatically adjusting BIOS (basic input/output system) option value. The method is implemented through the process as follows: a BIOS automatic detecting and correcting code module is set in a server system equipped with a GPU (graphic processing unit) with memory larger than 4G; when detecting that the GPU with the memory larger than 4G exists, the module automatically corrects the option value of Above 4G Decoding and preserves a corrected result in an NVRAM (non-volatile random access memory), and then a server is automatically restarted, so that PCIE (peripheral component interface express) equipment can perform decoding in space above 4G. Compared with the prior art, the method for automatically adjusting the BIOS option value has the advantages that operation of manual changing of Above 4G Decoding options can be reduced, and accordingly, time and labor can be saved during production on the production line, the work efficiency is improved, the practicality is high, and the method is easy to implement and popularize.
Description
Technical field
The present invention relates to computer communication technology field, a kind of practical, method of being automatically adjusted BIOS option value.
Background technology
It is known that server is whole network system and the core calculating platform, many important data all preserve on the server, and a lot of network services run the most on the server, and therefore the quality of server performance determines the performance of whole application system.
In order to improve the performance of server, we can use some parts such as high performance GPU, high-performance network interface card.But when using some high performance units, if their internal memory is more than 4G (such as NVIDIA K40 GPU), then the OPROM of these parts will be mapped to the space i.e. High memory section of more than the 4G of internal memory.So BIOS is accomplished by open Above 4G Decoding option, in order to PCIE device can be decoded in the space of more than 4G.But Above 4G Decoding is acquiescence disabled, it would be desirable to first being opened by Above 4G Decoding option before bios code performs, otherwise BIOS can be repeated the retraining of PCIE, the phenomenon of a kind of reset repeatedly occurs.Be introduced into the BIOS setup page in other words to find this option and revise and preserve and the PCIE device such as GPU plugged the most again, the most relatively time-consuming arduously, more do not meet the working specification producing line.
Based on this, now provide a kind of method being automatically adjusted BIOS option value.
Summary of the invention
The technical assignment of the present invention is for above weak point, it is provided that a kind of practical, method of being automatically adjusted BIOS option value.
A kind of method being automatically adjusted BIOS option value, it realizes process: at collocation internal memory more than in the server system of the GPU of 4G, BIOS is set and automatically detects amendment code module, in the presence of this module detects the GPU that internal memory is more than 4G, automatically the option value of amendment Above 4G Decoding be saved in NVRAM and the most automatically restart server so that PCIE device can be decoded in the space of more than 4G.
The process of above-mentioned module detection GPU memory size is:
First the internal memory used in BOM is collected more than the DeviceID of the GPU of 4G and is created in an array；
Starting server system, bios code module is started working, during work performs, and the DeviceID of detection PCIE device, check whether in the array of above-mentioned establishment, judge whether that internal memory is more than the GPU of 4G with this.
In the presence of having internal memory to be more than the GPU of 4G, then Above 4G Decoding option value it is revised as Enable and is saved in NVRAM, the most automatically restarting server；After restarting server, BIOS detects that Above 4G Decoding option is opened, and the GPU at this moment allowing internal memory be more than 4G can be decoded in the space of more than 4G.
A kind of method being automatically adjusted BIOS option value of the present invention, has the advantage that
A kind of method being automatically adjusted BIOS option value of this invention, it is possible to reduce manually change the operation of Above 4G Decoding option, so can be time saving and energy saving when producing line and producing, and improves work efficiency；This invention explains with the server architecture of Intel platform, but the method is not limited to the server of Intel platform, and the server at other platform has general using value in computer platform, practical, it is easy to accomplish, it is easy to promote.
Accompanying drawing explanation
Accompanying drawing 1 is the flowchart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the invention will be further described.
Under normal circumstances, in BIOS, Above 4G Decoding option is that acquiescence is closed.If employing interior 64 PCIE device (such as NVIDIA K40 GPU) that there is more than 4G, we need first to be opened by Above 4G Decoding option before bios code performs, otherwise BIOS can be repeated the retraining of PCIE, the phenomenon of a kind of reset repeatedly occurs.
For solving the problems referred to above, as shown in Figure 1, the present invention proposes a kind of method being automatically adjusted BIOS option value, for collocation internal memory more than the GPU(such as NVIDIA K40 GPU of 4G) server system, we are by amendment code, in the presence of the GPU that internal memory is more than 4G being detected, the automatically option value of amendment Above 4G Decoding be saved in NVRAM and the most automatically restart server PCIE device can be decoded in the space of more than 4G.This invention explains with the server architecture of Intel platform, but the method is not limited to the server of Intel platform, and the server at other platform has general using value in computer platform.
In technique scheme, NVRAM is nonvolatile random access memory Non-Volatile Random Access
Memory；Above 4G Decoding is the option in the BIOS setup page, and responsible setting is turned on and off 64 equipment in the decoding more than 4G address space, and Disabled is not enable, and Enabled enables.
The concrete technical scheme of said method is:
S11: first the internal memory used in BOM is collected more than the DeviceID of the GPU of 4G and is created in an array.
S12:BIOS code in the process of implementation, detects the DeviceID of PCIE device, checks whether to judge whether that internal memory is more than the GPU of 4G with this in the array that S11 creates.
S13: if be more than the GPU of 4G with the presence of internal memory, then be revised as Above 4G Decoding option value in Enable the NVRAM that preserves the most automatically restarting server.
S14: after restarting server, BIOS detect that Above 4G Decoding option is opened, then the GPU allowing internal memory be more than 4G can be decoded in the space of more than 4G.
Above-mentioned detailed description of the invention is only the concrete case of the present invention; the scope of patent protection of the present invention includes but not limited to above-mentioned detailed description of the invention; suitably change that it is done by claims of a kind of method being automatically adjusted BIOS option value of any present invention of meeting and any described technical field those of ordinary skill or replace, all should fall into the scope of patent protection of the present invention.
