7.4 Hardware
New hardware must first be installed or connected as directed by the
vendor. Turn on external devices and start the appropriate YaST module.
Most devices are automatically detected by YaST and the technical data
is displayed. If the automatic detection fails, YaST offers a list of
devices (model, vendor, etc.) from which to select the suitable device.
Consult the documentation enclosed with your hardware for more
information.
IMPORTANT: Model Designations
If your model is not included in the device list, try a model with a
similar designation. However, in some cases the model must match
exactly, because similar designations do not always indicate compatibility.
