IMPORTANT: Do not select Always Show Preboot Menu if you have AutoYaST or kickstart
bundles assigned to any devices, because the Preboot Services Menu interrupts the PXE boot
process, keeping the AutoYaST or kickstart bundles from being deployed on the device. The
Preboot Services Menu only has options for doing imaging work, not for installing operating
systems.
Therefore, select either Never Show Preboot Menu or Show Preboot Menu if CTRL+ALT is
Pressed for your Preboot Services Menu option, which allows PXE-enabled Linux devices to
automatically implement the AutoYaST or kickstart bundles.
7 Click Apply or OK.
OK: Enables the change and exits the page.
Apply: Enables the change and retains focus on the page, so you can click Revert to
temporarily disable the configuration change.
8 To temporarily disable the change, click Revert and the ZENworks Management Zone settings
for the menu remain in effect.
29.6 Enabling PXE on Devices
To image a device using Preboot Services, you need to find out if the device is PXE capable, and
then make sure that PXE is enabled.
PXE code is typically delivered with newer devices (PC 99 compliant or later) on the NIC.
This section includes the following information:
Section 29.6.1, "Enabling PXE on a PXE-Capable Device," on page 392
Section 29.6.2, "Verifying That PXE Is Enabled on a Device," on page 393
29.6.1 Enabling PXE on a PXE-Capable Device
When PXE is enabled, it can lengthen the time of the boot process slightly, so most NICs have PXE
turned off by default. To enable PXE on a PXE-capable device:
1 Access the computer system BIOS and look at the Boot Sequence options.
The PXE activation method for a device varies from one manufacturer to another, but generally
one of the following methods is used:
Some BIOSs have a separate entry in the BIOS configuration to enable or disable the PXE
functionality. In this case, set either the PXE boot setting or the Network boot setting to
Enabled.
Some BIOSs extend the entry that allows you to configure boot order. For example, you
can specify that the system should try to boot from a diskette before trying to boot from
the hard drive. In this case, set the system to try Network boot before trying to boot from a
diskette or from the hard disk.
2 If PXE is not listed in the Boot Sequence options and if the NIC is embedded in the
motherboard, look at the Integrated Devices section of the BIOS, which might have an option
to enable PXE. PXE might be called by another name, such as MBA (Managed Boot Agent) or
Pre-Boot Service.
