/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
Add this line to ur fstab file to make it look for cdrom at start up
What this line does is to allow u to access your cd drive which is "/dev/cdrom" thru the directory "/mnt/cdrom". You will have to create the directroy "cdrom" inside /mnt for this to work or during mount process it'll give u an error.
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
This line does the same with floppy.
For more information on the meaning of these fields please go through man page of fstab you can get it by typing "man fstab" at the command line or try this link

Hope this is helpful to u.
FYI
***
The /etc/fstab file is just a simple text file that can be created with any editor. We will need an entry for the root filesystem and for the proc filesystem. Information about the format of this file can be found in the fstab(5) manpage or by looking at the /etc/fstab file on any of the popular GNU/Linux distributions. you can do the same to mount your other cd drives.
