A.2.2 Installation Problems
Installation problems are situations when a machine fails to install. It may fail entirely
or it may not be able to start the graphical installer. This section highlights some of
the typical problems you may run into, and oers possible solutions or workarounds
for these kinds of situations.
A.2.2.1 Checking Media
If you encounter any problems using the openSUSE installation media, check the in-
tegrity of your installation media. Boot from the media and choose Check Installation
Media from the boot menu. In a running system, start YaST and choose Software >
Media Check. Media problems are more probable with the media you burn yourself.
Burning the media at a low speed (4x) helps avoiding problems.
A.2.2.2 Hardware Information
Display detected hardware and technical data using Hardware > Hardware Informa-
tion. Click any node of the tree for more information about a device. This module is

Save the displayed hardware information to a le by clicking Save to File. Select the
