I am writing this detailed so that the principles are under-
stood. Unfortunately when you learn on a user-friendly mod-
ern distro, you are the treated almost the same way as M$
treats you ... does everything but tells you nothing.
1) Your CD-ROM needs to be recognised by your kernel.
If you do "dmesg | less" you will see a line like:
hdd: SAMSUNG CD-ROM SC-152C, ATAPI CDROM drive
2) Note this hdd or hdc or whatever.
3) Check what your /dev/cdrom points to.
do 'ls -al /dev/cdrom' you will see something like:
lrwxrwxrwx 1 root ... /dev/cdrom -> /dev/hdd
4) If it is pointed correctly, subsequent referencing will
have no problems (provided permissions are okay)
5) You need a mount point to be present. See if you have a
dir called /mnt/cdrom. Permission of 755 is adequate.
6) The full mount command is:
mount -t iso9660 /dev/cdrom /mnt/cdrom
7) Please note that mounting/ unmounting devices is a root
function, you need to su to root for this. There are a
few methods of user mounts, and even shortcuts, and a
simple command like "mount /mnt/cdrom" as an user would
do the trick. This bit is detailed for a full explana-
tion. Have a look LOST #010 below for a summary.
8) The desktop icon you are referring to is probably KDE.
I admit my ignorance on this score ...

Sub : User CDROM mount LOST #010
This is a security issue .... NOT recommended unless it is on
a stand alone box. Make the following changes to /etc/fstab,
(where the mount point is /cdrom). Then, $mount /cdrom ... as
an user will do the trick
/dev/cdrom /cdrom iso9660 defaults,nosuid,nodev,noauto,user 0 0
