First Steps
Usually all distributions ship a kernel configured with these options. Depending on your ker-
nel configuration, one of these files can be unavailable. In order to have both files, you
should make sure that your kernel is configured with the following options:

CONFIG_SCSI (SCSI support)

CONFIG_BLK_DEV_SR (SCSI CD-ROM support : provides /dev/scdX)

CONFIG_CHR_DEV_SG (SCSI generic support : provides /dev/sgX)
For more information about how to configure your kernel for recording CDs or DVDs, you
can refer to the generic Linux HOWTOs. For example see

CD-Writing HOWTO: http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-
formats/html_single/CD-Writing-HOWTO.html

CDROM-Writing HOWTO: http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-
formats/html_single/CDROM-HOWTO.html
Nero Linux uses /dev/sgX device files to communicate with your devices. That
way, Nero Linux can send vendor specific commands such as those used to
change the book type of a DVD.
2.2.1.3 External Devices
As all external devices are associated with a virtual SCSI device, the file name scheme is the
same as with real SCSI devices.
If you do not see your external device in the /proc/scsi/scsi file after you plugged it in, make
sure that the kernel is correctly configured. For more information please refer to your Linux
distribution documentation.
If your external device is inside the /proc/scsi/scsi file and not present in the recorders list of
Nero Linux, make sure you have the SCSI generic support enabled. Most of the time, load-
ing the ‘sg’ kernel module fixes this problem.
2.2.1.4 Serial ATA Devices
Some new recorders now come with a Serial ATA connector instead of the old IDE one.
These devices are correctly handled with the 2.6 kernel libata. However we strongly recom-
mand to use a kernel 2.6.19 or higher to use such devices without problems.
Serial ATA devices controlled by the libata are – like external devices – associated with a
virtual SCSI device so they should also appear in the /proc/scsi/scsi file.
2.2.2 IDE Devices Configuration
2.2.2.1 IDE Devices Configuration With 2.4 Kernels
With 2.4 kernels, all IDE devices that you want to be available in Nero Linux must use the
ide-scsi driver (even CD/DVD readers). This driver associates a virtual SCSI device with a
standard IDE device.
