1.2 What Is the Preboot Execution Environment
(PXE)?
The following sections provide information on using PXE in Configuration Management:
Section 1.2.1, "Understanding How Preboot Services Uses PXE," on page 17
Section 1.2.2, "Understanding the ZENworks NBPs," on page 17
Section 1.2.3, "Preparing to Use PXE," on page 19

1.2.1 Understanding How Preboot Services Uses PXE

PXE uses DHCP (Dynamic Host Configuration Protocol) and TFTP (Trivial File Transfer Protocol)
to locate and load bootstrap programs from the network. The PXE environment is loaded from the
BIOS on the NIC.
Preboot Services uses PXE to discover if there is Preboot Services work specified for a device and to
provide the device with the files necessary to execute the assigned work.
Using Preboot Services, you can automatically place an image on a device, even if the device's hard
disk is blank. You do not need to use the CD or DVD, or a ZENworks partition on the device.

1.2.2 Understanding the ZENworks NBPs

The Intel PXE specification defines mechanisms and protocols that allow PXE devices to use their
network interface cards (NICs) to find bootstrap programs located on network servers. In the PXE
specification, these programs are called Network Bootstrap Programs (NBPs).
