What is PXE

In computing, the Preboot eXecution Environment, PXE specification describes a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP.

The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and as of 2015 it forms part of the Unified Extensible Firmware Interface (UEFI) standard. In modern data centers, PXE is the most frequent choice^[1] for operating system booting, installation and deployment.

What hardware configuration is required for a computer to use PXE. At present, the integrated network card of most computer motherboards has the PXE boot function, which requires a wired connection to the network card, and generally does not support WIFI boot.
