ok, ide-cd is nuked by turing if off in the kernel
OR if it is a module you might try moving the module out of the way
mv /lib/modules/blah/blah/blah/ide-cd.o /someplace/safe/ide-cd.o

Do you have devfs mounted on /dev ?
I have normal dev on /dev and devfs on /devfs atm to satisfy different needs
of things out of my control.
If you have normal dev on /dev take a look at /dev/MAKEDEV.  I know little
about devfs but...

Do you get any /dev/scd?
Does 'cdrecord -scanbus' tell you anything useful ?


hmmm, does anyone know of a stand alone version of 'cdrecord -scanbus' ?
I find its usefullness extends beyond cdrw's (eg usb-scsi).

Have fun,
Duncan
