hi

when i tried as per your instruction that time it will see like

[root@localhost ~]# hdparm -I /dev/cdrom
/dev/cdrom: No such file or directory

so what i want ot do sir

Open /boot/grub/grub.conf file and add all-generic-ide at the end of kernel line. Save file and reboot machine.
Check if Linux detects CD Driver on reboot. Execute hdparm command again.

Did you add all-generic-ide at the end of kernel line?

kernel /boot/vmlinuz-2.6.18-8.el5 ro root=LABEL=/ pci=nommconf rhgb quiet all-generic-ide
