What Is PXE Boot And How Does It Work?
PXE Boot, or Preboot Execution Environment, is a standardized client-server environment that allows booting a computer over a network. It works by loading a small operating system from a remote server, which then takes control of the client machine. This allows network administrators to deploy operating systems, firmware updates, and other software to multiple devices simultaneously, without the need for physical media.
In a PXE Boot setup, the client machine (in this case, a Lenovo ThinkPad) contacts a PXE server using the Dynamic Host Configuration Protocol (DHCP) and requests an IP address and a boot image. The PXE server then sends the boot image to the client, which boots from the received image. This allows for remote management and deployment of operating systems, making it a convenient and efficient way to manage multiple devices.
