First Steps
Nero Linux 10
Usually, Linux distributions automatically configure everything so that only recorders use this
driver. In such cases, you will not be able to use your CD or DVD readers in Nero Linux and
you have to make the device use the ide-scsi driver.
Before you configure a device, make sure that you have configured your kernel with the fol-
lowing options:

CONFIG_BLK_DEV_IDESCSI (SCSI emulation support)

CONFIG_SCSI (SCSI support)

CONFIG_BLK_DEV_SG (SCSI generic support)
Configuring a device so that it will use the ide-scsi driver is done by providing a specific ar-
gument hdx=ide-scsi to the kernel command line. For example, if the device file correspond-
ing to your recorder is /dev/hdb, you will have to provide hdb=ide-scsi to the kernel command
line.
If you do not know how to do this refer to your distribution documentation to find out how to
pass options to the kernel at boot time. Note that most of the actual distributions provide so-
me graphical frontends to modify the boot loader parameters:

For Red Hat Linux run ksconfig (this application is called Kickstart Configurator).
When the application is running, click Boot Loader Options and fill the Kernel Parame-
ters field.

For SuSE Linux run YaST2, select System in the left pane and then double-click Boot
Loader Configuration. Once the module is launched, click Edit Configuration Files to
set up the device parameters.
2.2.2.2 IDE Devices Configuration With 2.6 Kernels
With 2.6 kernels, the native IDE CD-ROM driver called ide-cdrom has been completely re-
written to use the latest technologies available and permit optical disc recording. This driver
includes DMA acceleration that lets you use high-speed devices (like DVD recorders).
Accordingly, the ide-scsi driver (that has been used with lower version kernels) has been de-
precated. If you continue using this driver with a 2.6 kernel your devices will not be available
with Nero Linux (note that you will also receive a warning message from the kernel at boot
time).
In order to use an IDE device with Nero Linux under a 2.6 kernel, you must associate it with
the ide-cdrom driver. Therefore, the kernel command line must not be associated with the
"old", ide-scsi driver (no hdXX=ide-scsi parameter).
If you do not know how to do this refer to your distribution documentation.
2.2.3 Setting Correct Permissions on the Devices Files
2.2.3.1 Setting Permissions For Static "/dev" Support
If you want to give other users access to all disc devices you can do this in Linux by setting
correct permissions for corresponding device file names. This takes place in the operating
system and not in Nero Linux.
