Preboot Services utilizes the following to make its 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 Linux Management can use PXE to launch Preboot Services.
Preboot Services bootable CD or DVD: Used where PXE is not installed or where you want to manually perform a Preboot Services operation.
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.
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.
