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.
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").
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 ...
When a network-connected computer boots up, its IP stack broadcasts BOOTP network messages requesting an IP address assignment. A BOOTP configuration server replies to the request by assigning an IP address from a pool of addresses, which is preconfigured by an administrator. BOOTP is implemented using the User Datagram Protocol (UDP) for ...
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]
Windows RE is installed alongside Windows Vista and later, and may be booted from hard disks, optical media (such as an operating system installation disc) and PXE (e.g. Windows Deployment Services). [23] A copy of Windows RE is included in the installation media of the aforementioned operating systems. It is a successor to the Recovery Console.
For DOS remote boot to work, the RPL boot loader is loaded into the client's memory over the network before the operating system starts. Without special precautions the operating system could easily overwrite the RPL code during boot, since the RPL code resides in unallocated memory (typically at the top of the available conventional memory).
Software that requires real-time input - Since all input at a thin client is sent over the network before it is registered by the operating system, there can be substantial delay. This is a major problem in software that requires real-time input (i.e. video games). Diskless nodes run the software locally, and as such, do not have this problem.
