G.7.1 Troubleshooting During the Boot Process
While booting ZENworks imaging, there are several things that you can do to help troubleshoot if
there is a problem:
Press Esc to see the kernel messages. Usually, messages are shown for failures.
Screen 3 (press Alt+F3) is used to show the progress of the linuxrc process. It lists progress
results, what linuxrc is doing, which modules are loaded, and so on.
Screen 4 (press Alt+F4) is used to show output from the modules during the linuxrc process.
Screens 1 (press Alt+F1), 3, and 4 can be used to help determine which part of the process is
failing or causing a problem.
Screens 3 and 4 indicate which drivers are loaded.
If a drive is loaded properly but fails in some way, view screen 4 to see if there is an outdated
driver.
If the boot process fails, the first command line parameter to use is acpi=off.

Prompt
When the prompt is displayed, there are a few tools that you can use to gather information about the
hardware:
hwinfo: This utility is used by linuxrc to load hardware. You can use
determine exactly what hardware was recognized.
Pipe to "less," because
If you need to contact Novell Support for help, you should capture the output from
to a file for their use. You can gather the most information with this command:
pci
hwinfo –pci –log /logfilename
where
You can then mount a device, such as a thumb drive or other USB device, and save the output
file for later use. You might also be able to use FTP to save the file where it can be available.
ethtool: This is a valuable tool (contained in a ZENworks distribution) that can be used to
change the configuration on most Ethernet network devices. See the online help for information
on using the ethtool utility.
