F.8.1 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:
Š Press Esc to see the kernel messages. Usually, messages are shown for failures.
Š
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.
Š
Screen 4 (press Alt+F4) is used to show output from the modules during the linuxrc process.
Š
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.
Š
Screens 3 and 4 indicate which drivers are loaded.
Š If a drive is loaded properly but fails in some way, view screen 4 to see if there is an outdated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.
