Is there any way to see what OS X is doing when it's booting up when no chime is played? Possible Duplicate:
  How can I see the system status during boot?  




I have had the hard drive in my iMac replaced and now I'm trying to restore it from my TimeMachine back up. I thought the TimeMachine back up was corrupt but maybe I'm just not patient enough, or I'm misunderstanding the restore process.

I'm able to restore successfully, but on reboot the machine shows me the white screen with the Apple logo and the spinner. I can hear some occasional sounds from the hard drive in the machine. It's been at this screen for a good hour now. The occasional hard drive sounds make me wonder if it's doing and fsck or similar operation on the drive before the system boots.

No chime has been played yet by the system. So the usual Cmd-V and Cmd-S solutions to see what it's doing or to boot to single user mode aren't working for me.

Is there any way to see what OS X is doing at boot time? I'm thinking something akin to the terminal window that modern Linux distros like CentOS can show you at boot time. The ones that let you see the step-by-step boot messages as they happen.
