LINUX--PXE Installation System

PXE (Preboot execute environment, pre-boot execution Environment)

Is the latest technology developed by Intel Corporation, working in Client/server network mode, supporting workstations to download images from remote servers over the network, and thus support booting the operating system through the network, during the boot process, the terminal requires the server to assign IP addresses, and then TFTP (trivial File Transfer Protocol) or MTFTP (multicast trivial File Transfer Protocol) protocol to download a boot package to native memory execution, completed by this boot package terminal (client) basic software setup, This directs the terminal operating system to be pre-installed in the server. PXE can boot multiple operating systems
