How does PXE boot work?

PXE works with Network Interface Card (NIC) of the system by making it function like a boot device. When the client receives this information, it contacts the TFTP server for obtaining the boot image. TFTP server sends the boot image (pxelinux. 0), and the client executes it.

How do I boot with iPXE?

How does PXE work with Network Configuration Manager?

Make sure that the PXE server and the PXE client are located on a physically secure network, such as in a data center, to prevent unauthorized access to your site. When a client boots with PXE, Configuration Manager provides the client with a boot image to use. Configuration Manager uses a boot image with an exact architecture match.
