What is PXE Boot and How Does it Work?

PXE Boot, or Preboot Execution Environment, is a technology that allows computers to boot from a network location rather than a local hard drive. This is achieved through a combination of DHCP, TFTP, and a PXE-enabled network card. When a computer is set to boot from the network, it sends a DHCP request to the network server, which then provides the necessary information for the computer to download the boot image from a TFTP server.

The boot image is typically a small operating system or a boot loader that can then be used to install a full operating system or run a diagnostic tool. PXE Boot is commonly used in enterprise environments to simplify the process of deploying new computers or reinstalling operating systems on existing ones. It is also useful for troubleshooting and repairing computers that are unable to boot from their local hard drive.

What is SCU and How Does it Relate to PXE Boot?

SCU, or System Configuration Utility, is a tool used to configure and manage the settings of a computer’s BIOS or UEFI firmware. It provides a user-friendly interface for adjusting settings such as boot order, network settings, and security options. In the context of PXE Boot, SCU is used to enable the PXE Boot option and configure the network settings necessary for the computer to boot from the network.

SCU is typically accessed by pressing a key during the computer’s boot process, such as F2 or Del. Once in SCU, users can navigate to the boot settings and enable PXE Boot, as well as configure other settings such as the boot order and network protocol.
