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, if one kind is arranged in each mainboard more
Special display configuration file, will increase the cost of software in this way, also be unfavorable for improving the experience of user；Solution of the invention is thought
Road is one basic GOP of setting, for executing the graphics driver process on basis, it is possible to understand that it is the figure of optimized integration function
Shape driving；By setting multiple display configuration mirrorings, then select corresponding display configuration mirroring with reality according to the model of mainboard
Existing corresponding display configuration, improves the general degree of process, reduces software development cost.
Based on the embodiment of the present invention 2
The present embodiment is for illustrating the realization principle of the invention under pure UEFI BIOS/firmware framework:
Pure UEFI BIOS does not have CSM module, does not support the display configuration mode of traditional VBIOS, but the GOP used
(Graphic Output Protocol driver is for graphics driver is extended to UEFI firmware to driver
Interface, so as to replacing tradition VBIOS (video BIOS) in the initialization such as booting resource requirement behavior), UEFI BIOS can be simultaneously
Comprising multiple display configuration mirrorings named with GUID, therefore can be before GOP operation, in GetVbtData function, root
The display mirror image to be read dynamically is modified according to different configurations (GPIO dynamic detection mainboard model can be used), reaches a BIOS
It is performed simultaneously the effect of a variety of different display configurations；Implementation step includes:
Show that configuration tool BMP (Binary Modification Program) is set according to hardware display interface with Intel
Meter is edited GOP configuration file (i.e. basis GOP).
In BIOS operational process, before GOP operation, it is based on GetVbtData function, is wanted according to different configuration modifications
The GUID of the display configuration mirroring of reading；
Normal start-up operation system.
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:
UEFI BIOS can wrap the display configuration mirroring of multiple names of GUID simultaneously, i.e., we wrap simultaneously in BIOS
The GOP configuration file that LVDS and closing LVDS is opened containing one, then in BIOS operational process, before GOP operation,
In GetVbtData function, according to BIOS Setup option or according to the hot plug of eDP (Embedded DisplayPort)
Pin judges whether user uses LVDS, then dynamically modifies the display configuration mirroring to be read, and reaches dynamic and turns off or on
Built-in display LVDS function, can avoid result in the problem of Linux systems such as ubuntu and fedora can not normally start.
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, before GOP operation, in GetVbtData function, mirror is configured according to the display to be read of different configuration modifications
Picture；
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.
