I installed LinuxNERO on my box (fedora core 2) but it does not see my external unit (the DVD burner) - only my internal one - I checked all the /dev settings and all the modules (see listings below).

xcdroast sees both drives properly and I can mount / unmount etc. on them. All automounters are disabled and also no warning concerning that is given when staring Nero

The unit is an iomega SuperDVD at the USB

Sincerely Yours

Stefan

Are you sure that you have no disc in your DVD device when you are starting NeroLINUX ? If the device is mounted, then Nero will not be able to open it exclusivly.

Yes - I tested both
A) without any disk
b) with a disk and no mount active (df does not display the device and automounters off)

I now tried it on my Laptop to test different hardware too.
The same effect.
Only diference - it is a SMP kernel (due to the HT Pention IV which
is seen as 2 CPU System) -and the internal burning device is
a DVD burner.

Is it related to the fact that there is already a unit with ID = 0 ?

Another starnge feature occured :
when exiting Nero a system message goes to the /var/log/messages
that some
CPU#1 running in modulated clock mode
(only CPU#1 - the CPU#0 does not get a new clock)
and thus after a few minutes (nero did not exit properly) the CPU
(due to an overclocking ?) started to overheat - This happens
only if I try to exit after burning with the internal device -
an exit after no burn process behaves OK.
