1.3.6 Intel Active Management Technology (AMT)

The Intel AMT functionality allows you to accurately identify devices, even if they have had
physical drive replacements. This provides ZENworks Preboot Services with persistent device
identification by providing ZENworks with nonvolatile memory for storing the unique device
identity.
With AMT and Preboot Services, if a device has a new, unformatted hard drive, ZENworks can
instantly and accurately identify the device and apply the appropriate Imaging bundle. If a device's
hard drive is inactive or its drive is replaced, ZENworks can automatically identify the device in a
preboot environment and provide the appropriate ZENworks-created image during a system rebuild.
AMT with ZENworks also provides easier hardware upgrading capability. For example, to upgrade
applications, some of your device hardware might not meet the minimum requirements. With AMT
and Preboot Services, as soon as the hard drives are replaced and before any agents or operating
systems are installed, you can continue to assign Imaging bundles using the device's ZENworks
identity without having to re-register the device.
If you are using Intel AMT, support for it should be enabled in the
zmgprebootpolicy.conf

1.4 The Preboot Services Processes

The following sections explain how the Preboot Services processes work:
Section 1.4.1, "A Typical Preboot Services Operation," on page 26
Section 1.4.2, "Illustrating the Preboot Services Processes," on page 27

1.4.1 A Typical Preboot Services Operation

A typical Preboot Services operation flows as follows:
1. An Imaging bundle is created in ZENworks Control Center and assigned to a PXE-enabled
device.
2. The PXE-enabled device starts to boot.
3. The device sends a DHCP discovery request to determine the IP address of the Preboot
Services Imaging Server.
4. The DHCP server responds with an IP address for the device to use.
5. Novell-proxydhcp responds with the IP addresses of the TFTP server, as well as the filename of
the Preboot Services bootstrap program (
6. The PXE device downloads the Preboot Services bootstrap program using novell-tftp.
7. After the Preboot Services bootstrap program is downloaded and executed, the device checks
novell-zmgprebootpolicy to see if there is any imaging work to do.
8. If there is imaging work to do (as contained in an Imaging bundle that is assigned to the
device), the device performs the following task
ZENworks Imaging: Downloads the Configuration Management imaging environment
from the server so that the it can be booted to Linux.
