If you don’t have iso image, first you need to make a bootable CD image, and then burn it. Notice that on some modern distributions, cdrecord is renamed to wodim, and mkisofs to genisoimage, but the parameters below should be the same.
mkisofs -o bootcd.iso -b FDOEM.144 FDOEM.144
cdrecord -v bootcd.iso

Most mount commands support the user option. If you make an entry such as the following in /etc/fstab:
/dev/sbpcd /mnt/cdrom iso9660 user,noauto,ro
then an ordinary user will be allowed to mount and unmount the drive using these commands:
mount /mnt/cdrom
umount /mnt/cdrom
