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.
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 ...
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.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
At boot time, a workstation that has been set to boot from PXE will issue a BOOTP request via the network. Once the request is received, the DHCP Server will supply an IP address to the machine, and the DNS server will point the client computer to the RIS server, which in turn will issue a disc boot image (often called the "OS Chooser").
The Trivial File Transfer Protocol (TFTP) is a simple lockstep communication protocol for transmitting or receiving files in a client-server application. A primary use of TFTP is in the early stages of nodes booting on a local area network when the operating system or firmware images are stored on a file server.
The client computer is set to boot from the network card using PXE or Etherboot. The client requests an IP address, and tftp image to boot from, both are provided by the DRBL server. The client boots the initial RAM disk provided by the DRBL server via tftp, and proceeds to mount an nfs share (also provided by the DRBL server) as its root ...
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 ...
