2.1.2 NeroLINUX requirements
In order to use NeroLINUX you will need at least a 2.4 kernel. To be plainly
usable, especially with high-speed recorders like DVD recorders, a 2.6 kernel is
highly recommended.
2.2 Devices configuration
Under Linux, all the devices are associated to one or more specific file(s) called
device file. All the device files that are available on your machine are located
inside the /dev directory.
But, depending on the version of the Linux kernel you are using, your recorder
device filename may differ, due to the low-level driver it is using. In this chapter
you will find some explanations about discovering your device filenames and how
to set access on them.
If you have enough technical competences, you can safely skip this section. In
any case, if NeroLINUX detects that something is misconfigured on your system,
it will warn you when starting.
2.2.1 Device filenames under Linux
Currently, you can have many different interfaces on a recorder: IDE, SCSI, USB
or FireWire (IEEE 1394).
2.2.1.1 IDE devices
Actually, most internal recorders are connected to the IDE bus. Linux assign
them a device file according to their position on this bus (bus number and
master/slave settings). Basically, you should have the following naming
convention:
 /dev/hda : Primary Master device
 /dev/hdb : Primary Slave device
 /dev/hdc : Secondary Master device
 /dev/hdd : Secondary Slave device
2.2.1.2 SCSI devices
SCSI recording devices are handled by two different drivers under Linux, and so
two different 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 NeroLINUX to communicate with the device
(X is a number identifying your device)
If your recorder is correctly recognized by the Linux kernel it should appear in the
file /proc/scsi/scsi. Unfortunately, there is no way to determine the X number from
the SCSI coordinates of your recorder. But usually, the numbers are used
incrementally, starting from 0, corresponding to the position of the device in the
/proc/scsi/scsi file.
