Advanced system requirements
Under Linux, all the devices are associated with specific files called device files. All device
files that are available on your machine are lo
to the low-level driver it is using.
In this chapter you will find explanations on how to find your device file names and how to
set access on them. In any case, if Nero Linux detects that something is misconfigured on
your system, it will warn you
14.1.3.1 Explanation to device filenames under Linux
Currently, you can have many different interfaces on a recorder: IDE, SCSI, USB, FireWire
(IEEE 1394) or Serial ATA.

SCSI devices
SCSI recording devices are handled by two different drivers under Linux, and so two differ-
ent device files are created to handle one physical device:

/dev/srX or /dev/scdX : Used only to read data from media

/dev/sgX : Used by Nero Linux to communicate with the device
If your recorder is correctly recognized by the Linux kernel it should appear in th
/proc/scsi/scsi. Unfortunately, there is no way to determine the X number fr
coordinates of your recorder. But usually, the numbers are used incremen
0, corresponding to the position of the device in the /proc/scsi/scsi file.
Usually all distributions are shipping a kernel configure
