PXEserverer

PXEserverer is a network booting protocol that allows a client computer to boot from a server over a network connection. PXE, which stands for Preboot Execution Environment, is a standardized method that enables computers to start up and load their operating systems without needing local storage devices like hard drives or SSDs. It is commonly used in enterprise environments for deploying operating systems, performing system maintenance, or running diagnostic tools on multiple machines simultaneously.

To function, a PXE server requires a DHCP server and a TFTP server. When a PXE-enabled client computer powers on, it broadcasts a DHCP request. The DHCP server responds with an IP address and information about the TFTP server, including its IP address and the name of the bootloader file. The client then uses TFTP to download the bootloader from the TFTP server. This bootloader is a small program that initializes the network interface and loads the operating system kernel or other boot files from the network.

The PXE process typically involves several steps. First, the client requests an IP address. Second, it obtains the location of the boot server. Third, it downloads the initial boot program. Finally, it executes the boot program, which can then load a full operating system or other required software. PXE's ability to boot without local storage makes it a valuable tool for managing and deploying systems efficiently.
