Hi,
Take CD0 out of the storage folder and put in the devs folder, under the folder device drivers.
Now take your CD0 file and read it with the ed command or notebook, and make sure your file is set up to read your cdrom. device should be set to scsi etc. you will need to check your Amiga manual for how to set this part up. If you don't have one leave me a note and I will try to find my old manual and get the exact info back to you. I put all my Amiga's away last year, and unfortunately have none around to look at, but if I have to I will dig out my old A3000 and set it up real fast and look at the CDO setup. Now another thing is what kind of cdrom are you using?
Is your terminating resistors installed?
Is it an inside or outside installation?
What kind of scsi card are you using?
and last but not least and very important
Is your A2K made by Atari?
