Activate and deactivate the DMA mode for your IDE hard disks and your IDE CD and DVD drives in the installed system with ‘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 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.

Configure a joystick connected to the sound card with ‘Joystick’. Select your joystick type in the list provided. If your joystick is not listed, select ‘Generic Analog Joystick’.

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 3.11.3, “Keyboard Properties”.

When configuring the mouse in the graphical environment, click ‘Mouse Model’ to access the SaX2 mouse configuration. Refer to Section 3.11.2, “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.

Connect and turn on your scanner then select ‘Scanner’ to configure it. Most supported scanners are detected automatically. Select the scanner to configure and click ‘Edit’. If your scanner is not listed, click ‘Add’ to open the manual configuration dialog. Select the appropriate vendor and model from the list and click ‘Next’ to proceed with the installation. To modify a configured scanner, select it then click ‘Edit’.

After the scanner has been determined by either automatic detection or user selection, installation is carried out. Click ‘Finish’ to complete the installation. If the installation is successful, a corresponding message appears. To test your scanner after installation, insert a document into your scanner and click ‘Other’+‘Test’.

3.3.12.1. Scanner Not Detected

Only supported scanners can be automatically detected. Scanners connected to another network host cannot be detected. The manual configuration distinguishes three types of scanners: USB scanners, SCSI scanners, and network scanners.

USB Scanner

After the scanner is selected, YaST attempts to load the USB modules. If your scanner is very new, the modules may not be loaded automatically. In this case, continue automatically to a dialog in which to load the USB module manually. Refer to the YaST help text for more information.

SCSI Scanner

SCSI devices are normally detected. Specify the device, such as /dev/sg0. If problems arise, refer to the YaST help text. Remember always to shut down the system before connecting or disconnecting a SCSI scanner.

Network Scanner

Enter the IP address or the hostname. To configure a network scanner, refer to the Support Database article Scanning in Linux (http://portal.suse.com/sdb/en/index.html, keyword scanner).

If your scanner is not detected, the device is probably not supported. However, sometimes even supported scanners are not detected. If this is the case, proceed with the manual scanner selection. If you can identify your scanner in the list of vendors and models, select it. If not, select ‘Cancel’. Information about scanners that work with Linux is provided at http://cdb.suse.de/ and http://www.sane-project.org/.

	Assigning a Scanner Manually
Assign the scanner manually only if you are absolutely sure. An incorrect selection could damage your hardware.

3.3.12.2. Troubleshooting

Your scanner may not have been detected for one of the following reasons:

• The scanner is not supported. Check http://cdb.suse.de/ for a list of Linux-compatible devices.

• The SCSI controller was not installed correctly.

• There were termination problems with your SCSI port.

• The SCSI cable is too long.

• The scanner has a SCSI light controller that is not supported by Linux.

• The scanner is defective.

	Warning
SCSI scanners should not be connected or disconnected while the system is running. Shut the system down first.

For more information about scanning, see Chapter 16, Kooka—A Scanning Application (↑Reference).

Use ‘Sound’ to configure a sound card. Most sound cards are detected automatically and listed. Select the one to configure or modify then click ‘Edit’.

If YaST is unable to detect your sound card automatically, click ‘Add’ to open a dialog in which to select a sound card vendor and model. Refer to your sound card documentation for the information required. Find a reference list of sound cards supported by ALSA with their corresponding sound modules in /usr/share/doc/packages/alsa/cards.txt and at http://www.alsa-project.org/~goemon/. After making your selection, click ‘Next’.

Configure TV and radio cards with ‘TV Card’. If your card was automatically detected, it is displayed in the list. In this case, select the card and click ‘Edit’. If your card was not detected, click ‘Add’. If you have already configured TV or radio cards, select a card to modify then click ‘Edit’.

During the automatic hardware detection, YaST attempts to assign the correct tuner to your card. If you are not sure, simply keep the setting ‘Default (recognized)’ and check whether it works. If you cannot set all channels, click ‘Select Tuner’ and select the correct tuner type from the list.

If you are familiar with the technical details, you can use the expert dialog to make settings for a TV or radio card. Select a kernel module and its parameters in this dialog. Also check all parameters of your TV card driver. To do this, select the respective parameters and enter the new value in the parameter line. Confirm the new values with ‘Apply’ or restore the default values with ‘Reset’.

Configure audio settings if your TV or radio card is connected to the installed sound card. Make the connection with a cable from output of the TV or radio card to the external audio input of the sound card. If you have not yet configured your sound card, select ‘Configure Sound Card’ to configure it as described in Section 3.3.13, “Sound”.

If your TV or radio card has speaker jacks, you can also connect the speakers directly without using the sound card. There are also TV cards without any sound function, which do not require an audio configuration, such as those for CCD cameras.

When editing a configuration, you can also configure the TV stations by clicking ‘TV Channel’. Set the proper ‘TV Standard’ and ‘Frequency Table’ for you area and click ‘Scan the Channels’. A list of stations appears. After scanning has been completed, click ‘OK’ to return to the configuration dialog.
