I'm trying to reset nvram but when I'm holding option+command+p+r the my MacBook Pro just keeps restarting 3 sec interval. I have succeeded in past but now I doesn't work. Only thing that has been changed since last time is CD/DVD drive which was replaced by apple provided CD/DVD drive.
Is there any workaround or fix?

Typically, getingt at least two-three rounds of the chimes when holding the NRAM Reset

or from Terminal.app copy & paste:
sudo nvram -c

I just keeps restarting over and over again. I tried it for one minute. Terminal thing worked.
