The invention is further explained below with reference to the figures and examples.
Fig. 1 is a flowchart of a first embodiment of a setting method of a computer display function according to the present invention, as shown in fig. 1, in this embodiment, the setting method includes the following steps:
s1, providing a first interactive interface for selecting a mainboard display mode or an external display card display mode in a DOS environment;
s2, if the mainboard display mode is selected, switching the first interactive interface into a second interactive interface for selecting an independent display mode or a combined display mode;

and S5, if the external display card realization mode is selected, switching the first interactive interface into a fifth interactive interface for selecting multiple display card interfaces, and calling corresponding function functions to realize corresponding display card interface functions based on the selection of the user.
In this embodiment, a graphical interactive interface is provided for a user through display setting software running under a DOS (Disk Operating System) System, and the user gradually sets corresponding display requirements through the graphical interactive interface. The display setup software may be implemented using the WBAT development tool, which is a batch enhancement tool that simulates the dialog box of a windows interface in a DOS system.
The display setting software construction flow is as shown in fig. 2, under the DOS environment, a word stock of the language used by the display setting software is added through WBAT, and then the language running environment of the software is set. For example, by adding a Chinese character library, a Chinese character running environment of the software can be set by using an HZK16 dot matrix character library, and the interactive interface constructed in this way can interact with users by using Chinese characters. In addition, a multi-language word stock can be added, then the default language running environment of the software is set, and the function of language switching is provided for the user to select. And then programming a text box interface through a WBAT configuration file, wherein the WBAT mainly comprises WBAT.COM, WABT.INI, PAL.INI and BAT script files, setting text box edition in the BAT script configuration file, putting up an interface frame, and then setting a text box, an icon and the like in the interface frame. Finally, corresponding function links are typed in for each established icon, and thus, the corresponding function is called to realize the corresponding function after the icon is clicked.
The language running environment of the display setting software is, for example, Chinese, as shown in fig. 3, when the interactive interface constructed by the software is Chinese information, the software finds out the offset position of the corresponding Chinese character in the HZK16 according to the internal code of the input information, opens the character library file HZK16, offsets the file pointer to the Chinese character to be found according to the found offset position, reads the Chinese character matrix and displays the Chinese character matrix on the screen.
The operation interface of the display setting software formed by the method is shown in fig. 4, and the function of the software program mainly comprises two modules: a setting program of a motherboard display register and a setting program of an external graphics card display CMOS (complementary metal Oxide Semiconductor).
In conjunction with fig. 1 and 5, when the display setup software is run in the DOS environment, the software will provide a first interactive interface for selecting the motherboard display mode or the add-on graphics card display mode (S1).
When the user selects the main board display mode through the first interactive interface, the software switches the first interactive interface to the second interactive interface, and provides options of the independent display mode and the combined display mode through the second interactive interface (S2).
And when the user selects the independent display mode through the second interactive interface, the software switches the second interactive interface into a third interactive interface, and the third interactive interface is used for providing options of the multiple functional interfaces. The functional interfaces include a Video Graphics Array (VGA) Display Interface, a Digital Visual Interface (DVI) Display Interface, a Digital Video Interface (DP) Display Interface, and a flat Panel Display Interface, and are used for connecting an external Display, and different functional interfaces are required to be connected with the external Display due to different models of the Display (S31). Then, the script file of the software calls the independent display function, and performs corresponding dispersion according to the variables introduced by the user' S selection of the various function interfaces, and calls the corresponding function interface function to set the selected interface function (S32). For example, the user selects the VGA display interface through the third interactive interface, the variable value corresponding to the VGA display interface is 1, the independent display function performs dispersion according to the variable 1 transmitted by the selection, and the VGA function interface function is called to set the VGA interface function. And the rest is done in the same way.
When the user selects the combined display mode through the second interactive interface, the software switches the second interactive interface to a fourth interactive interface for providing an option of combining the plurality of functional interfaces (S41). The functional interface combination includes various combinations of the above-described various functional interfaces, for example, a combination of a VGA display interface and a DVI display interface, a combination of a VGA display interface and a Panel display interface, and a combination of a VGA display interface and a DP display interface. Then, the script file of the software calls a combined display function, performs corresponding dispersion according to the variables introduced by the selection of the plurality of functional interface combinations through the combined display function, and calls the corresponding functional interface function to set the function of each interface in the selected combination (S42). For example, the user selects the combination of the VGA display interface and the DVI display interface through the fourth interactive interface, the variable value corresponding to the VGA display interface is 1, the variable value corresponding to the DVI display interface is 2, the combined display function performs dispersion according to the variable 1 and the variable 2 transmitted by the selection, the VGA function interface function is called to set the VGA interface function, and the DVI function interface function is called to set the DVI interface function. And the rest is done in the same way.
Specifically, the functional interface function completes the setting of the corresponding interface function through the following registers and INT10H, wherein,
5F64h register:
setting the display device subfunction when BH is 00 h;
setting display device options:
bits 7-1 ═ Retention
Bit0 is forced to be executed even in the same display device.
The setting of the Bit of the CX register is shown in Table 1, and when the Bit of the functional interface is set to 1, the display is enabled, and when the Bit is set to 0, the display is turned off.
TABLE 1
Figure BDA0000650014910000091
INT10H is a service provided by the BIOS to the screen and display.
The interface function setting flow is as shown in fig. 6, the function interface function calls the 5F64h register, the high Bit BL is 00h, the Bit of the low Bit BL is set, Bit7-1 is reserved, Bit0 is set to be forcibly executed, and thus the setting of the 5F64h register is completed. Then, the function interface function calls the CX register to set its Bit to 1, and if the VGA display interface is selected, sets Bit0 of the CX register to 1. After the setting of the Bit of the CX register is completed, INT10H is called, and the value of the Bit of the CX register is written into the AH register, so that the setting of the corresponding functional interface is completed. And the rest functional interfaces and the combination of the functional interfaces are arranged in the same way.
Fig. 5 shows a flow of the external graphics card displaying the COMS setting program, and with reference to fig. 1 and 5, the display setting software is run in a DOS environment, and the software provides a first interactive interface for selecting a motherboard display mode or an external graphics card display mode (S1).
When the user selects the display mode of the external display card through the first interactive interface, the software switches the first interactive interface into a fifth interactive interface, and provides selection of multiple display card interfaces through the fifth interactive interface (S51), where the display card interfaces include a PCI (Peripheral Component Interconnect) display card display interface and a PCIE (PCI express, a new generation bus interface) display card display interface.
The script file of the software calls the external graphics card display function to perform corresponding dispersion according to the variable introduced by the selection of the graphics card interface, and calls the corresponding graphics card interface function to set the selected graphics card interface function (S52).
The independent display card displays the setting, the common buses are PCI and PCIE, and when the external display card is set to display, the embodiment adopts the cmos method and combines the BIOS function to realize the setting of the interface function of the display card. Adding two Bit detection functions and realizing functions of the CMOS under the BIOS in advance:
1) selecting PEG mode (PCI-E), setting Bit1 Bit to 1by program, and executing PEG mode when BIOS detects Bit1 Bit to 1;
2) if PCI mode is selected, the program sets Bit2 to 1, and executes PCI mode when BIOS detects Bit2 to 1.
At most, only one Bit of the two Bit bits is 1, and all 0 bits are the default mode or the last setting is memorized.
When the display function of the external graphics card sets the PCI flag bit or PCI-E flag bit in the CMOS, 1Byte data is written into a certain register in the CMOS, and the following process is illustrated in fig. 7 by taking the CMOS register as an example. The 70H and 71H registers are channel entries for reading CMOS register values, wherein the 70H register is unreadable and writable, has a length of 8 bits, and is used for setting data addresses in CMOS. The 71H register is readable and writable, 8 bits in length, to set the value in the 70H port address.
First, an address (parameter) of a CMOS register for storing a flag bit to be set is inputted, the inputted register address is written into an 80H register (i.e., is or-processed with a value in 80H), and then written into a 70H register, and then the inputted variable data (flag bit) is written into a 71H register based on selection of the inputted variable data (flag bit) and the address of the register stored in the 70H register, thereby completing the setting of the CMOS. For example, when the user selects PCI, the incoming variable is written to a certain register bit of CMOS through registers 70H and 71H, and the setting of the flag bit is completed. After that, the 70H register is cleared.
Upon restart after the CMOS value setting is completed, the BIOS will update the display mode. The flow of the BOIS more display mode is shown in FIG. 8. And transmitting an address of the CMOS register stored with the zone bit, performing OR processing on the register address and the value stored in the 80H register to write the register address into the 80H register, then writing the register address into the 70H register, reading the zone bit information from the 71H register and returning the zone bit information to a program, and finally clearing the 70H register. Thereby completing the setting of the display function of the external display card. Similarly, the 70H, 71H registers are channel entries for reading the CMOS register values.
In the first embodiment of the method for setting the computer display function, provided by the invention, a graphical interface software is provided under a DOS system, an INT10H is used for realizing the setting function of the display mode of the mainboard, and the COMS method and the BIOS function are combined to realize the setting of the interface function of the display card, so that the operation is simple and convenient, and the requirements of users are met.
