Preferably, module is run, for copying the basis VBIOS to memory, modifies memory based on the variance codes
In basic VBIOS and close LVDS function to form new VBIOS, run the new VBIOS.
Preferably, application of the above-mentioned a kind of display and configuration system under the BIOS environment with CSM.
The beneficial effects of the present invention are: different VBIOS are arranged according to different display interfaces to adapt to different hardware, it is arranged
One basis VBIOS is using as comparison basis, based on different VBIOS in the difference of basic VBIOS to modify the base in memory again
Plinth VBIOS can be applicable in the demand of various display drivings on single basic VBIOS.
Detailed description of the invention
Fig. 1 show the schematic diagram of the display starting step based on the embodiment of the present invention.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
Based on the embodiment of the present invention 1
The present embodiment is for explaining in the computer-related display field problem, reason and solution: display
Technology always in upgrading and change, meanwhile, for the competition between various criterion, different manufacturers, deposit simultaneously always in the market
In multiple technologies, and in the case where alternative mainboard interface technology is numerous, each corresponds to one that video card needs
VBIOS (i.e. display card BIOS, display configuration), will increase the cost of software in this way, is also unfavorable for improving the experience of user；It is existing
A solution is the multiple VBIOS of setting, but can dramatically increase software cost in this way, and computer system is also made to face operation
The problem of stability.Resolving ideas of the invention is one basic VBIOS of setting, for executing the video driver stream on basis
Journey, it can be understood as basic technology/common technology of various VBIOS；Then according between different VBIOS and basis VBIOS
Difference obtain corresponding difference code (i.e. variance codes)；Basic VBIOS is loaded into memory and waits operation, then according to difference
Code revision basis VBIOS, so can be the smallest to obtain new VBIOS (i.e. the full version of the various VBIOS)
Meet the needs of various VBIOS under memory requirement, while not will cause compatibility/runnability problems again.
Based on the embodiment of the present invention 2
The present embodiment is for explaining the utilization under the BIOS/firmware framework for having CSM (compatible support module) module, CSM
Unlatching allows BIOS to support UEFI starting and MBR starting, i.e. compatible UEFI system and Legacy system simultaneously, at this time BIOS
Display configuration to use traditional VBIOS, but a VBIOS can only be wrapped in bios code framework, that is to say, that can only include
A kind of display configuration；In the case of this, implementation steps of the invention include:
A, show configuration tool BMP (Binary Modification Program) according to the aobvious of different mainboards with Intel
Show that interface carries out configuring multiple VBIOS, but only wrap a VBIOS in BIOS, is temporarily named as VBIOS_D4.dat；
B, compare tool, the difference generation of the VBIOS and VBIOS_D4.dat of more other difference display interfaces with binary system
Code (i.e. variance codes)；
C, traditional VBIOS is a PCI OptionROM, therefore it is (i.e. poor OEM code can be added in bios code
Different code), copy VBIOS mirror image (basic VBIOS) arrives memory, before executing (basic VBIOS's) VBIOS code, according to not
VBIOS content is (i.e. according to different mainboards in same configuration (can use GPIO dynamic detection mainboard model) dynamic modification memory
Type selects different VBIOS), it thus can achieve a BIOS while wrapping the effect of multiple VBIOS.
Based on the embodiment of the present invention 3
If the present embodiment is for explaining that the user mentioned in background technique does not have LVDS display screen or application no at all
LVDS screen, then after loaded and displayed driving, the problem of user can not install the Linux systems such as ubuntu and fedora at all, by
It is the problem of system is not normally functioning in main technical problem, basic ideas are that can be closed according to the needs of reality
Built-in display LVDS function；Simultaneously for more choices of technology purpose, the present embodiment explain how off/on LVDS
Function, specific step include:
Configuration tool BMP (Binary Modification Program) compiling tradition VBIOS (i.e. base is shown with Intel
Plinth VBIOS)；
Compare tool with binary system, compares the configuration variance of built-in display LVDS opening and closing；
OEM code is added in bios code, is mirrored to memory in copy VBIOS, before executing VBIOS code, according to
BIOS Setup option judges whether user uses according to the hot plug pin of eDP (Embedded DisplayPort)
LVDS, then VBIOS content in dynamic modification memory, reaches dynamic and turns off or on built-in display LVDS function.
Above-mentioned steps can also merge the step in embodiment 2 simultaneously, i.e., in same VBIOS, LVDS unlatching/closing
Code is different, can adapt to the demand of a variety of display situations.
Based on the embodiment of the present invention 4
The present embodiment is for illustrating display starting step as shown in Figure 1:
1, the power-on self-test of computer；
2, copy VBIOS is mirrored to memory, before executing VBIOS code, according to different configuration modification VBIOS contents；
3, load operating system.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
