Quick Start

NeroLINUX System configuration •

Another possibility, if you only want to give access to some users, is to create a
new group called for example nero and change the group of the device files
corresponding to your CD/DVD devices with it. Then give read/write permission
to the group on these device files and finally, just add all the users that are
allowed to use NeroLINUX to the new-created group.
2.2.4.2 Udev support
NeroLINUX supports udev, the new /dev file system implementation that are
used in SuSE Linux 9.2 and Fedora Core 3 for example. The only thing that can
appear is that a hot plug device that gets plugged in when NeroLINUX is already
started is not recognized. In that case, just restart NeroLINUX.
With this file system, all permissions are set during boot time using some specific
configuration files. So to make your modifications permanent, you have to change
the files located in /etc/udev/. For more details, you can have a look to udev FAQ.
2.2.5 Setting up DMA acceleration on IDE devices
DMA acceleration provides an improvement in throughput for the disc drives, and
let you safely use all your recording devices. Depending on your Linux kernel and
distribution configuration, you might have DMA acceleration that is automatically
enabled on startup.
If your hardware supports it, it is generally a good idea to enable DMA
acceleration not only for IDE hard disk drives, but also for disc drives such as
CD/DVD readers and recorders. Please note that if one of your devices has no
DMA acceleration, NeroLINUX will warn you when starting the application.
To enable DMA acceleration on one of your device, you can run the following
command (as root):
hdparm –d1 /dev/hdX
(where X is the letter corresponding to the IDE device)
This settings is not permanent. If you want to enable DMA at boot time, you can
add the command above in one of your startup scripts. As these scripts are
distribution dependant, please check your distribution documentation to find out
how to do this. Please note that most of the distribution have some graphical
fontends to configure this.
For example, with SuSE Linux distributions, you can use YaST2 to setup the
DMA mode of your IDE devices. To do this, launch YaST2 and select the
Hardware item in the left pane and then double-click on IDE-DMA Mode. Once
the module is launched, make sure that all your disc drives DMA mode is set to
‘On’.
