1) It's not clear from your description, did you power down the system 
before connecting and powering-up the scsi drive if it was an external drive.  
Linux scans the scsi devices on boot-up.

2) The scsi cdrom driver needs to be either compiled with the kernel, or
loaded as a module.  The command "cat /proc/devices" should show 

	Block devices: 
	  ...
	11 sr
	  ...

If this is not there, you may need to rebuild your kernel.

3) With the driver in the kernel your first scsi cdrom device should be
	brw-rw----    1 root     root      11,   0 Mar 10  2002 /dev/scd0

Hope this gets you further.
