Have you got SCSI cdrom selected as an option? On my machine the cd writer is /dev/sr0 (SCSI CDROM gives a module sr_mod). In dmesg I get : Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 sr0: scsi3-mmc drive: 24x/24x writer cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.12 Do you see anything like this? Regards, Edward
