Configure an infrared device with Hardware+Infrared Device. Click Start IrDa to begin configuration. You can configure Port and Limit Baud Rate here.

Configure graphics cards and monitors with Hardware+Graphics Card and Monitor. It uses the the SaX2 interface, described in Section 8.14, “SaX2”.

Configure a printer with Hardware+Printer. If a printer is properly connected to the system, it should be detected automatically. Find detailed instructions for configuring printers with YaST in Section 23.4, “Setting Up a Printer”.

Normally, the hard disk controller of your system is configured during the installation. If you add controllers, integrate these into the system with Hardware+Disk Controller. You can also modify the existing configuration, but this is generally not necessary.

The dialog presents a list of detected hard disk controllers and enables assignment of the suitable kernel module with specific parameters. Use Test Loading of Module to check if the current settings work before they are saved permanently in the system.

	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.

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.

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.

To add a DASD to the installed system, there are two possibilities:

	Note
In either case, you must run the commands mkinitrd zipl to make the changes persistent.

To add further FCP-attached SCSI devices to the installed system, use the YaST ZFCP module (Hardware+ZFCP). Select Add to add an additional device. Select the Channel Number (adapter) from the list and specify both WWPN and FCP-LUN. Finalize the setup by selecting Next and Close. Verify that the device has been added by checking the output of cat /proc/scsi/scsi.

	Note
To make the changes persistent through a reboot, run the following commands: mkinitrd zipl

Configure a joystick connected to the sound card with Hardware+Joystick. Select your joystick type in the list provided. If your joystick is not listed, select Generic Analog Joystick. After selecting your joystick, make sure that it is connected then click Test to test the functionality. Click Continue and YaST installs the required files. After the Joystick Test window appears, test the joystick by moving it in all directions and pressing all buttons. Each movement should be displayed in the window. If you are satisfied with the settings, click OK to return to the module and Finish to complete configuration.

If you have a USB device, this configuration is not necessary. Plug in the joystick and start using it.

To configure the keyboard for the console, run YaST in text mode then use Hardware+Keyboard Layout. After clicking the module, the current layout is displayed. To choose another keyboard layout, select the desired layout from the list provided. Test the layout in Test by pressing keys on the keyboard.

Fine-tune the settings by clicking Expert Settings. Adjust the key repeat rate and delay and configure the start-up state by choosing the desired settings in Start-Up States. For Devices to Lock, enter a space-separated list of devices to which to apply the Scroll Lock, Num Lock, and Caps Lock settings. Click OK to complete the fine-tuning. Finally, after all selections have been made, click Accept for your changes to take effect.

To set up the keyboard for the graphical environment, run the graphical YaST then select Keyboard Layout. Find information about the graphical configuration in Section 8.14.3, “Keyboard Properties”.

When configuring the mouse for the graphical environment, click Mouse Model to access the SaX2 mouse configuration. Refer to Section 8.14.2, “Mouse Properties” for details.

To configure your mouse for the text environment, use YaST in text mode. After entering text mode and selecting Hardware+Mouse Model, use the keyboard arrow keys to choose your mouse from the provided list. Then click Accept to save the settings and exit the module.

Most sound cards are detected automatically and configured with reasonable values during initial installation. To install a card added later or modify settings, use Hardware+Sound. It is also possible to switch the sequence of the cards.

Figure 8.5. Sound Configuration

If YaST cannot detect your sound card automatically, proceed as follows:

To change the configuration of a sound card, go to the Sound Configuration dialog, select a displayed Card Model, and click Edit. Use Delete to remove a sound card completely.

Click Other to customize one of the following options manually:

The volume and configuration of all sound cards installed are saved when you click Finish in the YaST sound module. The mixer settings are saved to the file /etc/asound.conf and the ALSA configuration data is appended to the end of the files /etc/modprobe.d/sound and /etc/sysconfig/hardware.
