Then that is most likely your problem.  I believe you need to:

1)  Make sure the /cdrom directory exists.  As part of setting up a system,
I usually make a /cdrom directory then execute the command:

touch /cdrom/CDROM_drive_not_mounted

This creates an empty file in the /cdrom directory to remind me that if I
can see that file, I haven't mounted the cdrom drive yet.

You only need to do this step the first time you set up the system for
mounting a cdrom.

2)  Insert the CDROM into the CDROM drive.

3)  Issue the command:  mount -t cd9660 -o ro /dev/cd0a /cdrom

If you give the mount command without a CDROM in the drive, you are asking
the CDROM drive to mount a non-existant disk.

4)  When I'm done with the CD, I use the command:  eject cdrom

Your mileage may vary.  I'm planning on getting amd to automagically mount
the CD drive.  I just need to get around to working on it.
