Thanks for the response,

>From my "/lib/modules/2.4.0-test7/modules.dep" file
/lib/modules/2.4.0-test7/modules.dep the modules were created OK:

/lib/modules/2.4.0-test7/kernel/drivers/block/pktcdvd.o
/lib/modules/2.4.0-test7/kernel/fs/udf/udf.o

However if I do a "lsmod" it shows that the modules udf and pktcdvd0
aren't being loaded and I don't have a clue why they aren't So then I do
a modprobe for both of them. 

# modprobe udf
[root@h000094b6613f /lib/modules/2.4.0-test7] 
# modprobe pktcdvd
[root@h000094b6613f /lib/modules/2.4.0-test7]
# lsmod
Module                  Size  Used by
pktcdvd                14180   0 
cdrom                  27452   0  [pktcdvd]	<--------
udf                    77648   0  (unused)
--- snip
# ls /dev/pktcdvd0
/dev/pktcdvd0
# cd /packages/udf/tools/
# ./pktsetup /dev/pktcdvd0 scd0
open device: No such file or directory
[root@h000094b6613f /packages/udf/tools] 

I just noticed something from the above. I have a cdrom and a cdr on my
machine. Both are IDE devices and I use scsi emulation for the cdr.
pktcdvd is using the cdrom and it should be the cdr.

Any suggestions?

Thanks,
Glenn
