A PXE client will not be able to boot if it only receives an answer from a non PXE enabled DHCP server. After parsing a PXE enabled DHCP server DHCPOFFER, the client will be able to set its own network IP address, IP Mask, etc., and to point to the network located booting resources, based on the received TFTP Server IP address and the name of ...
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 ...
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 ...
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").
GHOST could clone a disk or partition to another disk or partition or to an image file. GHOST allows for writing a clone or image to a second disk in the same machine, another machine linked by a parallel or network cable, a network drive, or to a tape drive. 3.1 uses 286 with XMS and could still run on OS/2.

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).
Unlike Acronis Cyber Protect Home Office and Norton Ghost, Clonezilla lacks an agent that can be installed into the operating system. Instead, Clonezilla was designed under the assumption that the disk should be cloned without interfering with the operating system.
