Abstract: A computer platform system image automatic loading method and system is proposed, which is designed for use in conjunction with a server on a computer production line for providing a system image automatic loading procedure for a number of computer platforms on the computer production line, and which is characterized by the use of network technology to remotely detect the model of each linked computer platform, and then download a model-compliant system image in a multicast manner to all of the linked computer platforms. This feature allows the loading of system image into computer platforms without having to remove hard disk modules therefrom and without the need to manually select a model-compliant system image, and therefore allows the computer production to be more efficient and reliable than prior art.
