WARNING: Configuration of the Hard Disk Controller
It is advised to test the settings before making them permanent in the system.
Incorrect settings can prevent the system from booting.
8.4.6 Hardware Information
Display detected hardware and technical data using Hardware > Hardware Information.
Click any node of the tree for more information about a device. This module is especially
useful, for example, when submitting a support request for which you need information
about your hardware.
Save the hardware information displayed to a file by clicking Save to File. Select the
desired directory and filename then click Save to create the file.
8.4.7 IDE DMA Mode
Activate and deactivate the DMA mode for your IDE hard disks and your IDE CD and
DVD drives in the installed system with Hardware > IDE DMA Mode. This module
does not have any effect on SCSI devices. DMA modes can substantially increase the
performance and data transfer speed in your system.
During installation, the current SUSE Linux Enterprise kernel automatically activates
DMA for hard disks but not for CD drives, because default DMA activation for all
drives often causes problems with CD drives. Use the DMA module to activate DMA
for your drives. If the drive supports the DMA mode without any problems, the data
transfer rate of your drive can be increased by activating DMA.
NOTE
DMA (direct memory access) means that your data can be transferred directly
to the RAM, bypassing the processor control.
