Based On Efi Bios Remote Assistance System Research And Design

With the development of Internet, computer science and its applications grow rapidly in many fields, especially in real-time control, information processing, communications, technical support and other areas. Computer Remote Assistance is a technology which provides a solution that technical expert can connect to a remote client via the Internet or other networks, and to assist clients to carry out computer maintenance and resource management. Remote computer-assisted techniques can be applied at the remote technical support, remote maintenance and management, as well as remote diagnostics. There have some products and solutions that based on computer remote assistance technology, which vary in many aspects. But all existing solutions and products have a client in operating system, which means that when the OS does not start, the entire system will not be able to run.The research presents a new remote assistance computer technology solutions, it would transfer the client form OS to EFI BIOS, thus computer in the pre-boot stage can be managed and controlled by a remote server. This means that technical expert can provide remote assistance and technical support to a computer which can not boot normally. Besides, the new solution can even apply to bare-meta computer. In addition, the client of this solution can not rely on server and independent operation, the end user can managing file, getting hardware information and communicating with a server through a graphical interface in pre-os stage.The research first discusses the EFI specification and its basic concepts and implementation process, such as EFI Framework, C / S mode, TCP / IP protocol and so on. Then some basic knowledge of EFI application and its implementation mechanism are introduced. Afterwards the application models, system architecture, client architecture, module design, key implementation, server design and key implementation concept of some important modules are detailed in this article. At last, the possible improvements and future work are issued...
