Abstract: A diskless computer-to-remote storage server operating system installation system and method, which uses a boot firmware and a network storage driver to establish disk connection with a logic unit space, enabling the operating system installation program to recognize a disk device for installation. The boot firmware is in charge of fetching network parameters. The storage driver is in charge of providing the installation program with network device operating function. The system and method of the invention eliminates the procedure of establishing a physical hard drive for making an operating system image for transmitting to the logic unit space, preventing an operation error due to being unfamiliar with the installation procedure. By means of eliminating image file making procedure, the invention greatly lowers the chance of human error during system establishment.
