Disable Firmware Password??

Hey everyone. At the company I work for we received a 2009 iMac back from one of our remote sites. The graphics user that had it was let go a couple months back and its been sitting there. To top it all off, the hard drive is toast.

I went to replace the hard drive and upon booting up Im not able to do anything. The machine wont eject the disc thats already in it and I cant get into anything like single user mode. When I try I get the box for firmware password protection.

The person's manager has no idea what the password would have been. Is there a way around this so I can get OSX reinstalled on it and redeploy the machine?

Thanks!

 

Nevermind I figured out a workaround to disable it.
