F.3.2 Command Line Parameters and Variables
There are four types of command line parameters that can be used with the ZENworks imaging
process. They are entered manually on the command line when booting from a CD or they can be

Kernel parameters: The valid parameters for the Linux kernel are found in the
Documentation/kernel-parameters.txt
Some devices have a faulty BIOS, where you must turn off ACPI processing for the kernel to
load properly. To do this, use the kernel parameter acpi=off. For more information, see

Linuxrc parameters: These parameters affect the way linuxrc detects hardware or sets
hardware settings. They are described briefly in the

F.4 Modifying ZENworks Imaging Resource Files
From time to time you might want to modify an imaging distribution by adding your own files.
These can be additional programs, scripts, data files, or updated Linux drivers.
You can use the following methods to update imaging resource files:
