In specific implementation, if the required content cannot be analyzed from the INF file of the specified network card driver (for example, the network card driver file does not exist), the network card driver cannot be imported, and at this time, the user is notified that the analysis fails, and the process is ended.
The step S1 specifically includes:
when the VOI terminal is started, downloading and operating a PXE starting module through a DHCP server; after the PXE starting module runs, the PXE starting module acquires the PID of the network card and the VID of the network card in the VOI terminal, and sends a downloading request to the network card driving server side according to the PID of the network card and the VID of the network card; after receiving the download request, the network card drive server determines a corresponding network card drive according to the PID of the network card requested by the VOI terminal and the VID of the network card, and provides a corresponding network card drive file and a configuration file for downloading by the VOI terminal;
after the VOI terminal downloads the network card drive file and the configuration file, the network card drive file and the configuration file are cached, and the PXE starting module guides the operating system to start.
In step S2, the loading and executing the network card driver file specifically includes:
