29.2 Setting Up the Preboot Services Methods
The Novell ZENworks Imaging Engine that performs the actual imaging of a device is a Linux
application. Unless you use automated Preboot Services with PXE-enabled devices, you need to
prepare a boot medium that has the Linux kernel, ZENworks Imaging Engine, and network drivers
installed.
The following sections contain additional information:
Š
Section 29.2.1, “Using Preboot Services (PXE),” on page 354
Š Section 29.2.2, “Preparing Imaging Boot CDs or DVDs,” on page 354
Š
Section 29.2.3, “Using the ZENworks Imaging Media Creator,” on page 356
Š Section 29.2.4, “Managing ZENworks Partitions,” on page 362
29.2.1 Using Preboot Services (PXE)
Preboot Execution Environment (PXE) is an Intel specification that allows a device to boot from the
network, instead of its hard drive or other local media. ZENworks Linux Management can use PXE
to launch Preboot Services.
In ZENworks Linux Management, Preboot Services uses PXE to find out if there is imaging work
specified for a device and to provide the device with the files necessary to boot to the ZENworks
Linux Management imaging environment.
Before you can use Preboot Services with automated Preboot bundles, you need to do the following:
Š
Install the ZENworks Linux Management Imaging and Preboot Services (PXE Support)
components on your imaging server.
Š
Enable PXE on the device.
Š
Have a standard DHCP server, either on your imaging server or on another network server.
Automated Preboot Services functions can also be performed using a ZENworks partition. For more
information, see
“Creating a ZENworks Partition” on page 362 .
Manual Preboot Services functions can be performed using CDs or DVDs. For more information,
see
Section 29.2.2, “Preparing Imaging Boot CDs or DVDs,” on page 354 .
29.2.2 Preparing Imaging Boot CDs or DVDs
If you have software for burning CDs or DVDs, you can create an imaging boot CD or DVD for
imaging operations. You have two options:
Š “Creating a Boot CD or DVD with Additional Files” on page 354
Š
“Creating a Boot CD or DVD without Additional Files” on page 355
For information on how to use the CD or DVD to perform disconnected imaging operations, see
Section 30.1.3, “Setting Up Disconnected Imaging Operations,” on page 424 .
Creating a Boot CD or DVD with Additional Files
This section describes how to create an imaging CD or DVD that contains more than the files
provided in the
bootcd.iso
image.
