/dev/scd* is no longer used. 2.6.x kernels no longer use scsi
emulation.
Make sure you are using udev by running (you might need to do
a 'urpmi udev' first)
tom # service udev status
udev is running [ OK ]
.... if not, run 'service udev start' and try again.
Then 'urpme devfs' and remove any devfs=mount statement
from lilo.conf (or you can change it to devfs=nomount )
Then.....

^^^^^^^^^^^^
No, remove that from lilo.conf and run 'lilo' after all the
above edits.

Run 'cdrecord dev=ATA -scanbus' You might see it
recommended to use 'dev=ATAPI' but that is deprecated already.
'dev=ATA' is the more correct form. Eg, here's mine;
tom # cdrecord dev=ATA -scanbus

Notice my burner is 1,1,0 So;
cdrecord -v -eject speed=24 dev=ATA:1,1,0 .......
....is my basic form for burning CDr's. speed= can be omitted
and your burner should try an use it's fastest speed, but I'd
suggest you use 1/2 of the lesser; your burner's speed or the
media you use. My burner is 52x, and I use 52x media, so I burn
at 24x. Notice from the "Warning:" that I could also use the
form 'dev=/dev/hdc' (burner is primary on the 2nd IDE channel).
I'd recommend usin 'dev=ATA:X,Y,Z'
You might also have somethin like this in /etc/modprobe.conf
# This file is autogenerated from /etc/modules.conf using
# generate-modprobe.conf command
install scsi_hostadapter /sbin/modprobe sata_via; /bin/true
You could have this if you'd done a fresh install. Since you
upgraded you can try running 'generate-modprobe.conf' That will
try to convert your existing modules.conf (2.4.x kernels) into a
suitable modprobe.conf (2.6.x kernels). Backup your existing
modprobe.conf first.
Either way you might need a line like this with the appropriate
driver for your burner. (Mine is 'sata_via' for an IDE/SATA
combo VIA mobo). I'm not positive on this, as my SATA drive also
uses SCSI emulation. IOW's, the modprobe.conf line above might
not be needed on your system. So if you don't have it, try a
test burn without it.
