Description

Technical Field

[0001] The present invention relates to the field of mini PC technology, and more specifically, to a display redirection method and system based on UEFI network. Background Art

[0002] Mini PC is a small, portable computer with pre-installed operating system, which can be directly plugged into a monitor, keyboard and mouse for use. It is usually used in business meetings, classroom teaching and public entertainment venues. However, with the increase in mini PC machines, traditional mini PC maintenance remains at the Windows level, and the maintenance of UEFI environment is relatively blank. For example, if the machine displays abnormally, it is necessary to enter the BIOS interface to view parameters. At this time, if there is a system that can remotely monitor the UEFI environment, it is very convenient to view the BIOS interface of the abnormal machine without connecting to a monitor.

[0003] The existing technology is to use a specific Intel CPU that supports the vPro function to achieve this remote UEFI environment monitoring. The existing solution must use a specific CPU, that is, a CPU that supports Intel vPro technology, and the cost of CPUs that support this function is often very high, and there are few optional types, which is not suitable for ordinary consumer and cost-sensitive products.

[0004] This has also led to the failure of many mini PCs to widely use this solution. Therefore, the industry urgently needs a universal and low-cost remote solution to fill the gap in remote UEFI environment monitoring and solve the pain point that machines with abnormal display cannot remotely monitor the BIOS interface.
