I've just toyed around with my system. I've notice that the SCSI driver
sees the CDROM as...
Host: scsi1 Channel: 00 Id: 06 Lun: 00
Vendor: YAMAHA Model: CRW4260 Rev: 1.0e
Type: CD-ROM ANSI SCSI revision: 02
I can't use the device until the sr_mod module is loaded then I get ...
Detected scsi CD-ROM sr0 at scsi1, channel 0, id 6, lun 0
sr0: scsi3-mmc drive: 6x/6x writer cd/rw xa/form2 cdda tray
You might want to check the /proc/devices file to see if an sr device is
listed (hopefully the 2.0.X kernels are similar to the 2.1.X kernels.)
Block devices:
2 fd
3 ide0
8 sd
9 md
11 sr
22 ide1
As far as dealing with a SCSI CD and an IDE CD I do things this way in
the /etc/fstab file...
/dev/hdd /cdrom/ide iso9660 noauto,user,ro 0 0
/dev/sr0 /cdrom/scsi iso9660 noauto,user,ro 0 0
Then I can just say 'mount /cdrom/ide' or 'mount /cdrom/scsi'. Works
like a champ!
