If it does not exist, switch the WEBUI interface again, reacquire the first frame buffer address in the BMC, obtain the first frame buffer data in the first frame buffer through the first frame buffer address, and judge whether the first frame buffer data exists first identification;

Execute the CPU interface switching operation. The CPU interface switching operation is: obtain the content of the CPU interface in the BMC, obtain the second frame buffer address, obtain the second frame buffer data through the second frame buffer address, and judge whether there is a second frame buffer data in the second frame buffer data. Two signs, if present, then output the second frame buffer data in the second frame buffer to the display controller;

If it does not exist, then execute the CPU interface switching operation again, reacquire the second frame buffer address in the BMC, obtain the second frame buffer data in the second frame buffer through the second frame buffer address, and judge whether the second frame buffer data is there is a first identifier;

or

Execute the WEBUI interface switching operation. The WEBUI interface switching operation is: obtain the frame buffer address in the BMC, obtain the address of the first memory in which the data in the frame buffer format of the WEBUI interface of the BMC is stored in the frame buffer address, and obtain the first frame buffer of the WEBUI interface data, judging whether there is a first identifier in the first frame buffer data, and if so, outputting the first frame buffer data in the first memory to the display controller;

If it does not exist, perform the WEBUI interface switching operation again, reacquire the first memory address in the BMC, obtain the first frame buffer data in the first memory through the first memory address, and judge whether there is the first frame buffer data in the first frame buffer data again. logo;

If it does not exist, then perform the CPU interface switching operation again, obtain the second memory address again, obtain the second frame buffer data in the second memory through the second memory address, and judge whether there is a second mark in the second frame buffer data again;

It should be noted that, in the description of this embodiment, the first frame buffer data and the second frame buffer data are data that the frame buffer memory can read, identify and store, and the data can be output through the display controller.

It should be noted that when the display controller displays the CPU interface, the BMC needs to be managed at this time, and the BMC management operation can be issued through the BIOS menu or the operating system;

Or switch to the WEBUI interface of the BMC, and manage the BMC through the display controller and the USB input interface of the BMC;

When the server is powered on, the display controller interface cannot be switched to the BMC WEBUI interface through the display output item. At this time, only the CPU interface can be displayed. After the server is powered on, the display controller interface can be switched through the display output item.

Different from the prior art, the present invention converts the WEBUI interface of the BMC into a frame buffer and outputs it through the display controller without transmitting it through the HTTP protocol, thereby avoiding attacks on the WEBUI interface from the network and improving the security of the WEBUI interface , and directly use the BMC's USB input interface to control the WEBUI interface, which improves the ease of use, and can also manage the BMC when the network is abnormal.
