YaST Disk Controller
About
YaST Disk Controller lists all the disk controllers on your system. The list shows the name of the disk controller, and whether or not it is a new controller (Yes/No).
Here you can decide which kernel module you wish to use for the drive controller. This may be a module included on the SuSE installation disks, or it may be a module provided by your disk controller manufacturer.
This also displays the status of the module; whether or not it is currently loaded. You are also given the option of loading the module in initrd, and adding module parameters.
Use the Test Loading of Module button any time you make a change. This will act as an added step to prevent system instability.
If your drive controller & drive controller kernel module allows for parameters to be passed, this is where you would enter this information.
When your changes have been made, first click Test Loading of Module to help prevent risking system stability before you click Finish.
