The core of the application is to provide a display switching method, a device, a server and a medium, which can improve the applicability of the server and the user experience.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
With the rapid development of cloud computing technology and internet industry, servers are increasingly widely applied in practical application, especially in occasions such as large-scale data centers and cloud computing bases, tens of thousands or even hundreds of thousands of servers are often deployed in one data center, so that the management usability of the servers becomes the most concerned problem of server use managers.
After the existing server is started, an on-board video graphics array interface (Video Graphics Array, VGA interface) on a main board is used for connecting display equipment by default, and it is required to be noted that the resolution of the on-board VGA interface is limited, and the scene display requirement of high-resolution display requirement cannot be met when the on-board VGA interface is required, and an additional independent display card is required to be arranged as a display interface so as to be convenient for connecting the display equipment. As the server defaults to use an on-board VGA interface as an interface for connecting display equipment, the display can not be output and displayed from an external independent display card. Therefore, it is necessary to provide a device that can output from the external independent video card when the external independent video card is connected, and output from the on-board VGA interface when the external independent video card is not connected.

It should be noted that, the preset value of the category code may be a binary value, and it is known that when the preset value is binary, the preset value may be set to 1-bit data, specifically 1 or 0; the preset value may also be set to 2-bit data, specifically 00, 01, 10 or 11, where, for the number of bits of the preset value, and when the preset value is multiple bits, the specific expression data string may determine the implementation manner according to the specific implementation scenario, which is not limited in this embodiment. Setting a preset value by using 1-bit data, and outputting and displaying modes corresponding to the preset value: output display is expressed by 0 through the video graphic array interface, and the output display mode corresponding to the preset value is as follows: the output display is indicated at 1 through the video graphics array interface.

Because the class codes corresponding to the two output display modes are set, and the class codes reach the preset value and do not reach the preset value, the class codes correspond to one of the two output display modes, are compatible with the two display modes, and at the moment, the applicability and the use experience of the server are improved.
On the basis of the above embodiment, as a more preferable embodiment, when the category code is a preset value, before determining to output the display through the video graphics array interface, it further includes:
the characterization determination is output by a Hardware register (hard Strap register) to the displayed position via the video graphics array interface as a first set point.
The specific representation mode of the first set value is as follows: bit [15] =1: select the Class Code for VGA device, expressed as: if the hardware register is a 32-bit register, then its 16 th is set to the corresponding binary 0 in a 32-length data string.
Wherein after determining, by the hardware register, the characterization to output the displayed position through the video graphics array interface as the first set value, further comprising:

judging whether the updated class code is consistent with the read class code;
if yes, entering a step of determining output display through a video graphic array interface;
if not, returning to the step of reading the category codes stored in the main board.
At this time, the accuracy of the display switching method is further improved, and the updated category codes are judged to be consistent with the read category codes, so that the category codes are accurately described if the updated category codes are consistent with the read category codes.

At this time, the accuracy of the display switching method is further improved, and the updated category codes are judged to be consistent with the read category codes, so that the category codes are accurately described if the updated category codes are consistent with the read category codes.
On the basis of the above embodiment, as a more preferable embodiment, further comprising:
the output display mode is set to be the priority of output display through the independent display card, which is higher than the priority of output display through the video graphic array interface. Because the VGA interface has low resolution, when two display devices with two output display modes are connected at the same time, the output display mode of high-resolution output display through the independent display card is preferentially used.

After the server is started, if the display is output and displayed through the video graphic array interface through the BMC, the PNOR drives the display equipment to display after the driving code is started; if the BMC is set to output and display through the independent display card, the PNOR drives the display device to display after driving the codes.
