Overview
In Novell®ZENworks®10 Configuration Management, Preboot Services provides functionality
that allows you to perform automatic imaging tasks on managed devices (Windows* Primary
Servers and Windows workstations) before their operating systems boot. You can also perform
manual imaging operations on these devices, as well as any other device with the supported file
system, such as legacy Windows workstations, Linux Primary Servers, and Linux workstations.
The following sections provide an overview of Preboot Services:
Section 1.1, “Brief Overview,” on page 13
Section 1.2, “What Is the Preboot Execution Environment (PXE)?,” on page 17
Section 1.3, “Preboot Services Functionality,” on page 19
Section 1.4, “The Preboot Services Processes,” on page 26
Section 1.5, “Preboot Strategies,” on page 34
1.1 Brief Overview
The following provides a brief overview of Preboot Services:
Section 1.1.1, “Preboot Services Functionality,” on page 13
Section 1.1.2, “Preboot Services Strategies,” on page 14
Section 1.1.3, “Imaging Bundles,” on page 14
Section 1.1.4, “Configuring Preboot Services,” on page 15
Section 1.1.5, “Setting Up Devices to Use Imaging Bundles,” on page 16
1.1.1 Preboot Services Functionality
Preboot Services allows you to automatically or manually do any of the following to a Windows
device when it boots:
Make an image of the device’s hard drives and other storage devices
Restore an image to the device
Apply an existing image to multiple devices
Run Imaging scripts on the device
To accomplish these tasks automatically using ZENworks Control Center, you simply need to have
PXE (Preboot Execution Environment) enabled on your devices, then have Imaging bundles
configured and assigned to the devices. The devices automatically execute these bundles when they
boot.
Preboot Services utilizes the following to make its imaging functions possible:
PXE (Preboot Execution Environment): An Intel* specification that allows a device to boot
from the network, instead of its hard drive or other local media. ZENworks Configuration
Management can use PXE to launch Preboot Services.

14 ZENworks 10 Configuration Management Preboot Services and Imaging Reference
novdocx (en) 16 April 2010
Preboot Services Bootable CD or DVD: Used where PXE is not installed or where you want
to manually perform a Preboot Services operation. This is applicable only for ZENworks
Imaging.
Preboot Services Bootable Diskette: Enables using the Preboot Services bootable CD or
DVD when the device doesn’t support booting from a CD or DVD. This is applicable only for
ZENworks Imaging.
ZENworks Partition: Enables you to set up a device for unattended imaging operations where
the device is not PXE-enabled or does not have access to PXE network services. This is
applicable only for ZENworks Imaging.
For more information on these methods, see Chapter 3, “Using Imaging,” on page 99.
1.1.2 Preboot Services Strategies
Following are some of the uses of Preboot Services:
Create and Restore Standard Images: Create base images from existing devices, as well as
restore images to any manageable device.
Set Up Devices for Future Reimaging: Set up devices so that the next time they reboot, they
do the imaging work that is contained in their assigned Imaging bundle.
Multicast Device Images: Apply an image of one device to many other devices. This is an
excellent feature for initially setting up a lab.
Restore Devices to a Clean State: Quickly and efficiently reset devices to an initial state, such
as in a lab.
For more information on these strategies, see Section 1.5, “Preboot Strategies,” on page 34.
1.1.3 Imaging Bundles
In ZENworks Control Center, Preboot Services tasks are contained in Imaging bundles. The
following Imaging bundle types are available:
Empty Bundle: A bundle with no initial tasks. You can quickly create this bundle without
performing all of tasks in the Create New Bundle wizard. Later, you can edit its details to add
assignments, actions, and so forth.
Imaging Script Bundle: Allows you to write a custom Imaging script. This provides detailed
control over ZENworks imaging operations, as well as most Windows-based preboot tasks.
This is applicable only for ZENworks Imaging.
Multicast Image Set Bundle: Specifies an image that can be sent through the multicast
protocol. This bundle allows you to send an image to a large number of devices in a single
operation, which minimizes network traffic. It is ideal for labs, classrooms, and staging areas.
This is applicable only for ZENworks Imaging.
Third-Party Image Bundle: Allows you to specify the third-party images that can be restored
on a device.
ZENworks Image Bundle: Lists one or more ZENworks images (base plus add-ons) that can
be restored on a device. This bundle allows you to define simple imaging operations.
To create one of these bundles: in ZENworks Control Center, click Bundles in the left pane, in the
Bundles panel click New > Bundle > Imaging Bundle > Next, then select a bundle type.

novdocx (en) 16 April 2010
For more information on these bundles, see Section 1.3.1, “Imaging Bundles,” on page 19.
1.1.4 Configuring Preboot Services
In ZENworks Control Center, you can set up default Preboot Services configurations for all of your
devices. Some settings can be overridden at the device, group, and folder levels.
You can configure the following settings per ZENworks Management Zone:
Novell Preboot Services Menu Options: The menu contains five options: 1) Start ZENworks
Imaging (automatically executes the bundle); 2) Start ZENworks Imaging Maintenance
(accesses the imaging maintenance mode prompt); 3) Disable ZENworks Partition; 4) Enable
ZENworks Partition; and, 5) Exit (resumes booting). You can configure whether the menu is
displayed upon booting, not displayed, or displayed only when Ctrl+Alt is pressed during
booting.
Non-Registered Device Settings: You can use Preboot Services to automatically name your
non-registered devices, using such criteria as prefixes, BIOS information (such as asset tags or
serial numbers), DNS suffixes, and you can set up DHCP or IP addresses.
Device Imaging Work Assignment: Work assignment rules are used to determine which
bundle should be applied to which device. The work rules use logic to determine whether a
device meets the requirements for applying the Imaging bundle. A rule is made up of filters that
are used to determine whether a device complies with the rule. The AND and OR logical
operators are used for creating complex filters for the rule.
Server Referral List: When a device boots, it is necessary for it to find its home Management
Zone to get its assigned imaging work. If multiple Management Zones exist on the network,
server referral lists provide a method for allowing a managed device to find its home zone.
Intel Active Management Technology (AMT): Intel AMT provides Preboot Services with
persistent device identification.
Third-Party Imaging Settings: You can upload WinPE (Windows Preboot Environment) and
third-party Imaging tools such as Microsoft Imaging engine (imagex.exe) and Symantec Ghost
(
ghost32.exe ). Before configuring the third-party Imaging settings, ensure that Microsoft
Windows Automated Installation Kit (WAIK) is installed on the device running the ZENworks
Control Center.
TFTP Replication Settings: You can replicate the changes made to the tftp directory on
other Imaging servers (Primary Servers or Satellites with the Imaging role). The
tftp directory
contains files such as configuration files and binaries used by ZENworks Configuration
Management to perform imaging tasks. The directory is located on the Imaging server in
/srv/
on Linux and in
%ZENWORKS_HOME%\share\ on Windows.
To configure these settings, click Configuration in the left pane to display the Configuration tab. If
it’s not expanded, click Management Zone Settings, then click Device Management > Preboot
Services to display the Preboot Services page.
For more information, see Section 1.3, “Preboot Services Functionality,” on page 19.

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).

18 ZENworks 10 Configuration Management Preboot Services and Imaging Reference
novdocx (en) 16 April 2010
NBPs are analogous to the bootstrap programs found in the Master Boot Records (MBRs) of other
boot media, such as hard drives, floppy disks, CDs, and DVDs. The purpose of a bootstrap program
is to find and load a bootable operating system. MBRs on traditional boot media accomplish this by
locating the necessary data on their respective media. NBPs accomplish this by using files found on
network servers, usually TFTP servers.
ZENworks Preboot Services uses two separate NBPs working together:
“nvlnbp.sys” on page 18
“pxelinux.0” on page 18
nvlnbp.sys
This NBP has the following responsibilities:
Detect various SMBIOS parameters and local hardware
Read the ZENworks identity information from the hard drives
Communicate with novell-zmgprebootpolicy to determine if there is any preboot work
applicable to the device
Present and manage the Novell Preboot Services Menu
If necessary, launch pxelinux.0 to execute the assigned preboot work
pxelinux.0
The primary purpose of this NBP is to load the operating system that is required to execute the
assigned preboot work.
The pxelinux.0 file is a modified version of part of an open source project called syslinux.
Although
pxelinux.0 is primarily a Linux loader, it is capable of loading other operating systems.
It operates by using configuration files located on a TFTP server to provide boot instructions. The
various
pxelinux.0 configuration files used by Configuration Management can be found on your
Imaging Server in the
/srv/tftp directory on Linux or the %ZENWORKS_HOME%\share\tftp
directory on Windows, where
%ZENWORKS_HOME% is the complete path of the ZENworks installation
directory.
In Configuration Management, when PXE devices are assigned preboot work, they are also told
which
pxelinux.0 configuration file they should use to execute that work. Similarly, when using
the Novell Preboot Services Menu, each menu option corresponds to a
pxelinux.0 configuration
file. For more information, see Section 2.4.4, “Editing the Novell Preboot Services Menu,” on
page 71.
For more information on
pxelinux.0 and its configuration files, see the syslinux home page (http:/
/syslinux.zytor.com/pxe.php).
For a copy of the Novell modifications to the syslinux open source project, see Novell Forge (http://
forge.novell.com).

1.2.3 Preparing to Use PXE
Before you can use Preboot Services with PXE, you need to do the following:
1. Install Novell ZENworks 10 Configuration Management SP3. For more information, see the
ZENworks 10 Configuration Management Installation Guide.
2. Enable PXE on your Configuration Management devices. For more information, see
Section 2.7, “Enabling PXE on Devices,” on page 96.
3. Have a standard DHCP server, either on your ZENworks Imaging Server or on another network
server where ZENworks is not installed. For more information, see “Configuring LAN
Environments for Preboot Services” on page 64.
NOTE: The PXE boot option is not supported on the XEN systems. Consequently, ZENworks
Imaging and ZENworks Third-Party Imaging in the PXE mode is not available on the XEN systems.

1.3.1 Imaging Bundles
Configuration Management uses Imaging bundles to apply Preboot Services work to devices. For
example, Imaging bundles can contain tasks, such as restoring an image, that are performed at the
time a device boots.
In order for a device to utilize an Imaging bundle, the bundle must be assigned to the device, its
group, or its folder.
The available Imaging bundles are:

Empty Bundle
This bundle contains no initial tasks. You can quickly create this bundle without performing all of
tasks in the Create New Bundle Wizard. Later, you can edit its details to add assignments, actions,
and so forth. For example, you could create an empty bundle, then in the bundle’s properties add the
Linked Application Bundle action as its only action.
Imaging Script Bundle
Allows you to write a custom Linux script that is executed on PXE-enabled devices. This provides
detailed control over ZENworks imaging operations, as well as most Linux-based preboot tasks.
For more information, see Section 3.3, “Configuring Imaging Script Bundles for ZENworks
Imaging,” on page 132.
Multicast Image Set Bundle
Specifies an image that can be sent using the multicast protocol. This bundle allows you to send an
existing image to a large number of devices in a single operation. It is ideal for labs, classrooms, and
staging areas.
For more information, see Section 1.5.6, “Multicasting Device Images,” on page 37 and Section 3.2,
“Multicasting Images for ZENworks Imaging,” on page 122.
Benefits
You can image multiple devices with the least amount of overhead. Devices to be imaged can have a
variety of operating systems installed on them, or even no operating system installed.
Using the multicast capabilities of your network, you minimize network traffic by sending the image
file across the network once for all devices to be imaged, rather than individually per device.
Limitations
Using the same image on multiple devices means they all have the same network identities.
However, you can install the ZENworks Configuration Management Imaging Agent (novell-ziswin)
on these devices prior to performing the multicast, because this agent saves each device’s network
identity settings and restores them after the multicast image is applied.
Third-Party Image Bundle
Allows you to specify the third-party images to be restored on a device. ZENworks supports:.
Microsoft* ImageX that uses the WIM image file format and WinPE as the distro.
Microsoft* ImageX that uses the WIM image file format and WinPE as the distro. The distro is
available as WAIK (Windows Automated Installation Kit) that can be downloaded from
