A high-level PXE overview. In computing, the Preboot eXecution Environment (PXE; often pronounced as / ˈ p ɪ k s iː / pixie, often called PXE boot (pixie boot), is a specification describing a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients.
gPXE is an open-source Preboot eXecution Environment (PXE) client firmware implementation and bootloader derived from Etherboot.It can be used to enable computers without built-in PXE support to boot from the network, or to extend an existing client PXE implementation with support for additional protocols.
iPXE is an open-source implementation of the Preboot eXecution Environment (PXE) client software and bootloader, created in 2010 as a fork of gPXE (gPXE was named Etherboot until 2008). [2] It can be used to enable computers without built-in PXE capability to boot from the network, or to provide additional features beyond what built-in PXE ...
Finally, the Preboot Execution Environment (PXE) version 2.0 was released in December 1998, and the update 2.1 was made public in September 1999 counting on TFTP as its file transfer protocol. [5] Intel has recently decided to widely support PXE within the new UEFI specification extending the TFTP support to all EFI/UEFI environments. [6] [7]
PXE may refer to: Preboot Execution Environment, booting computers via a network; Proof and Experimental Establishment, an Indian defense laboratory; Pseudoxanthoma elasticum, a genetic disease; Pentium Extreme Edition, a variant of the Pentium D microprocessor; PXE, an EP by Ecco2K
This typically contains NTLDR and is launched by the boot BLOB. Part BLOB This contains the actual boot runtime (i.e. the contents of the disk image including any Operating System [OS] files) and also includes the boot.ini (used by NTLDR) and ntdetect.com files which should be located within the root directory of the runtime. The size of the ...

As with the second-stage boot loader, network booting begins by using generic network access methods provided by the network interface's boot ROM, which typically contains a Preboot Execution Environment (PXE) image. No drivers are required, but the system functionality is limited until the operating system kernel and drivers are transferred ...
