Particular content is as follows:
Step S10, obtain target screen type, and from predetermined BIOS determine match with the type it is general defeated
Enter output valve；
Since the type of screen is very more, and the initiation parameter of different screen is different.Unmatched initialization ginseng
Number will lead to can not normally initial screen, therefore, terminal gets this when getting screen production requirement in the application
The type of target screen carries out parameter matching according to type.Type specifies the universal input output valve of the target screen, described
Universal input output valve is gpio value, and target screen does not provide universal input output valve or the output of provided universal input
Value needs to use after adjustment.The universal input output valve is sealed up for safekeeping in predetermined BIOS mainboard.Terminal is from predetermined BIOS
Middle determination and the matched universal input output valve of the type.Such as A screen has matching A type universal input output valve, B screen has
Matching Type B universal input output valve, and so on.
Step S20, the determining video card VBIOS to match with the universal input output valve from the predetermined BIOS；
Understandably, initialized target screen needs to light the target screen, and terminal needs to get the load of initialization
Body driving, in the present embodiment, which is stored in predetermined BIOS, acts on video card, and preserves in BIOS
A large amount of video card VBIOS, the video card VBIOS are VBIOS driving.Different video card VBIOS correspond to different types of screen
Curtain.Distinctive mark data of the universal input output valve as type, terminal will get defeated with universal input from predetermined BIOS
It is worth the video card VBIOS to match out.Such as A type universal input output valve is corresponding with the dedicated video card VBIOS of A type, and Type B is general
Input and output value is corresponding with the dedicated video card VBIOS of Type B.That is, terminal is according to universal input output valve from predetermined BIOS
It is middle to traverse various video card VBIOS and matched, so that the video card VBIOS to match is retrieved.
Step S30 obtains the time sequence parameter of the target screen, and the video card VBIOS is written in the time sequence parameter；
It include time sequence parameter in the target screen, the time sequence parameter is timing parameter, the time sequence parameter
In include a large amount of initialized target screens step time sequence parameter, such as memory timing parameter (i.e. memory time sequence parameter),
Lcd timing parameter (i.e. crystal display time sequence parameter) etc..The time sequence parameter can be obtained from target screen data
It arrives, i.e., time sequence parameter is provided by target screen, and terminal obtains the time sequence parameter of target screen, and by said write to video card
In VBIOS.The time sequence parameter provides the assignment that video card VBIOS is initialized, and as driver, video card VBIOS can
Realize being in communication with each other for hardware design and software design, so that the normal initialization of target screen is driven, and time sequence parameter specification
Initialization values in video card VBIOS.
Step S40 loads the video card VBIOS of write timing parameter according to the universal input output valve, described in driving
Predetermined BIOS initializes the target screen.
Universal input output valve is loaded into the video card VBIOS of write timing parameter, is read by universal input output valve
Enter the state of pin low and high level value, realizes that video card VBIOS interacts (such as UART), convenient reading with the hardware data of target screen
The working state signal etc. of target screen, so that controlling target screen enters initialization process.
In the present embodiment, each universal input output valve is all preset, parameter needed for corresponding to each target screen,
Different universal input output valves represents current goal screen and corresponds to different level values, and terminal is according to universal input output valve
Pullup or pulldown drives resistance, to get the specified drive level value of universal input output valve (gpio).And terminal according to
Universal input output valve (gpio) drive level value loads video card VBIOS, the time sequence parameter in the driving can be transmitted to mesh
Screen is marked, the hardware element of target screen is activated, to realize that the message between hardware component and software manipulation communicates, and will be right
The initiation parameter answered is applied in initialization process, so that predetermined BIOS be driven to initialize the target screen.
Specifically, the video card VBIOS to match with the universal input output valve determining from the predetermined BIOS
The step of include:
Obtain the corresponding video card VBIOS ID of the universal input output valve, from the predetermined BIOS determine with it is described
The video card VBIOS that video card VBIOS ID matches.
According to hardware circuit design, one group of universal input output valve (gpio value) is defined, and in BIOS, defines one two
Dimension group, each group of gpio value, the corresponding VBIOS of corresponding video card VBIOS ID, the video card VBIOS ID includes a
The time sequence parameter of the target screen；During BIOS initialization, one group of input and output of the universal input output are obtained
Value obtains one group of corresponding VBIOS according to the universal input output valve.
Further, the step S40 further include:
Step B1, obtains the first identifier of the video card VBIOS of write timing parameter, and obtains the video card VBIOS ID and make
For second identifier；
In order to guarantee target screen can normal initialization, need to the video card VBIOS of write timing parameter and general
Input and output value is verified.Verification mode is by the video card VBIOS to universal input output valve and write timing parameter
Carry out proof of identity.Different video card VBIOS has corresponding mark to describe, therefore the video card VBIOS of write timing parameter
There is corresponding mark, meanwhile, universal input output valve is that the key parameter of different types of target screen is distinguished in the present invention,
With corresponding mark.
Specifically, terminal extracts the first identifier of the video card VBIOS of write timing parameter, while extracting video card VBIOS ID
As second identifier.For example, the first identifier that terminal extracts in current video card VBIOS is, shield 1:Mouduleid=0x20,
Vid=10de, did=1024；And the video card VBIOS ID extracted is as second identifier, second identifier is screen 1:
Mouduleid=0x20, did=1024, vid=10de.
Step B2 is loaded if the first identifier is matched with the second identifier according to the universal input output valve
The video card VBIOS of write timing parameter, to drive predetermined BIOS to initialize the target screen.
After getting first identifier and second identifier, parameter attribute is carried out to the two and parameter value matches, such as video card
First identifier in VBIOS is screen 1, and second identifier is also screen 1, and parameter attribute (such as first identifier all the same of the two
It is screen 1 with second identifier, while has and only Mouduleid, vid, tri- attributes of did), and first identifier and the second mark
The parameter value (Mouduleid=0x20, vid=10de, did=1024) for knowing parameter attribute is also equal, it was demonstrated that when presently written
The video card VBIOS and universal input output valve of order parameter are mutually matched, and terminal will be executed to be added according to the universal input output valve
Carry the screen initialization step of the video card VBIOS of write timing parameter.
Step B3 returns to the class for executing and obtaining target screen if the first identifier and the second identifier mismatch
The step of type.
Conversely, as first identifier and second identifier mismatch, such as first identifier is screen 1, second identifier is screen 2, or
Parameter attribute Mouduleid, did, vid in first identifier and second identifier be not quite identical or first identifier in did=
1024, did=1280 in second identifier, that is, prove presently written time sequence parameter video card VBIOS and universal input output valve without
Method data compatibility cannot be applied in same production scene, and terminal will return to the step of executing the type for obtaining target screen at this time,
To reacquire correct universal input output valve and correct video card VBIOS.
The following are the present embodiment one to optionally perform example: further, to define one group of ID mark, institute per a VBIOS
It states ID mark and contains the first mark and the second mark, to form VBIOS array；The VBIOS array is contained in BIOS and deposits
In storage media.When the BIOS loads VBIOS according to universal input output valve (gpio), the corresponding relationship before basis is understood,
Obtain VBIOS ID.
VBIOS array is traversed in BIOS further according to VBIOS ID；BIOS program is right according to the first identifier of VBIOS ID
Than the VBIOS first identifier for including in the VBIOS array that traverses, when first identifier matching, then second identifier is carried out
Comparison judge correspond to the VBIOS and target screen one of VBIOS ID in current array when second identifier matching
It causes；VBIOS driving is loaded, and is accordingly initialized, target screen is lighted.
The present invention obtains the type of target screen, and the determining universal input to match with the type from predetermined BIOS
Output valve；The determining video card VBIOS to match with the universal input output valve from the predetermined BIOS；Obtain the target
The time sequence parameter of screen, and the video card VBIOS is written into the time sequence parameter；It is write according to universal input output valve load
Enter the video card VBIOS of time sequence parameter, to drive the predetermined BIOS to initialize the target screen.By above scheme, so that
BIOS mainboard can be compatible with a variety of different types of screens of matching, avoid BIOS and screen parameter is incompatible leads to production cost
Height, the inaccurate phenomenon of creation data occur, so that solving product quality cannot ensure, the low technology of production efficiency is asked
Topic, and then the compatibility of BIOS is improved, screen production cost is reduced, improves the quality of production of product, and improve product
Production efficiency, reduce subsequent product maintenance burden.
Further, it is based on first embodiment, proposes the second embodiment of this forwarding method, it is in this embodiment, described to obtain
After the step of taking the type of target screen further include:
Step a counts institute if the universal input output valve to match with the type is not detected from predetermined BIOS
All universal input output valves in predetermined BIOS are stated, to obtain the statistics number of all universal input output valves；
The type is corresponding with ID voucher, each ID is corresponding with a universal input output valve and VBIOS ID.?
The corresponding VBIOS ID of the corresponding universal input output valve of type may be not present in predetermined BIOS, terminal can not then detect
Matched universal input output valve, if matched universal input output valve is not detected, terminal needs to count in predetermined BIOS
All universal input output valves number, to search the reason of universal input output valve is not detected.
Step b exports the first prompt information, if the statistics number is greater than the first preset value to prompt predetermined BIOS
In there is no the universal input output valves that match with the type.
Specifically, if statistics number is greater than the first preset value, illustrate to save in current BIOS enough general defeated
Enter output valve sample size, i.e., it is because being not present in default BISO and type that matched universal input output valve, which is currently not detected,
Matched universal input output valve.Terminal will directly export the first prompt information, prompt that matching is not present in user preset BIOS
Universal input output valve.
Step c exports the second prompt information if the statistics number is less than or equal to the first preset value, pre- to prompt
If universal input output valve sample data is insufficient in BIOS.
If counting number is less than or equal to the first preset value, it was demonstrated that the universal input output valve saved on current preset BIOS
Sample data is not up to normal data amount, i.e. sample data deficiency leads to not detect from predetermined BIOS matched general defeated
Enter output valve, accordingly, in predetermined BIOS need to increase the sample data of more universal input output valves, terminal will export
Two prompt informations, to prompt universal input output valve sample data in predetermined BIOS insufficient.Further, in the second prompt information
It may include the prompt information for prompting user to import the universal input output valve to match with current goal screen.
Specifically, after the step b further include:
Step d after exporting first prompt information, obtains total storage medium capacity of predetermined BIOS, and statistics is default
Storage medium capacity shared by all VBIOS in BIOS, and stored and be situated between according to shared by total storage medium capacity and the VBIOS
Matter calculation of capacity storage medium occupancy；
Further, there is no matched universal input output valves and statistics number to be greater than the first preset value side in BIOS
Illustrate the storage medium off-capacity of current BIOS, therefore after exporting first prompt information, terminal can be obtained directly
Total storage medium capacity of predetermined BIOS is taken, and counts storage medium capacity shared by all VBIOS in predetermined BIOS, by VBIOS
Shared storage medium capacity/total storage medium capacity=storage medium occupancy.
Step e exports third prompt information if the storage medium occupancy is greater than the second preset value, pre- to prompt
If BIOS storage medium off-capacity.
Second preset value is the excessively high judgment criteria of storage medium occupancy, and it is default that storage medium occupancy is greater than second
Value, the storage medium for illustrating that current VBIOS is occupied is excessively high, and predetermined BIOS occupied multimedium by VBIOS, and there is no general
The situation of input and output value sample size deficiency can not save more VBIOS storage medium samples on i.e. current preset BIOS.
Therefore terminal will export third prompt information, prompt predetermined BIOS storage medium off-capacity, and the third prompt information mentions
Show that may also include request user in content increases BIOS medium or increase the content of BISO storage chip.The present embodiment passes through third
Prompt information prompts the storage medium on user BIOS insufficient, so that prompting user to notice is not detected matched universal input
The basic reason of output valve facilitates the restarting of initialization process so that user safeguards.
