Problem with Firmware load...
Just had the same problem as you PCMIKE and the PRAM reset instructions from Tompkinson are exactly correct.
Here is also a link to the instructions I used from Apple website:

Here is what you will see if it works correctly:
Since the combination of keys is a bit awkward to press while trying to hit the power key with your pinkie, you may need to try a couple times. If you still get the blank gray screen, just power off the Mac and try the sequence over. It took me a couple of tries to get all the keys pressed at the same time.
Also, once you get the black screen release the keys and you should launch right into the apple logo grey screen. After that OSX will launch and you will see a notice saying your firmware has been updated.
I guess if you never boot to the OSX screen, then you may have a deeper problem than I had.
Good luck

After doing this... Waiting for the second tone to release I get the same flashing logo and then finally a screen with some text (like singler user mode) then it gets an overlay with the.., "you need to restart your computer." if I restart I just get the flashing logo again and the machine never boots. Any other help??!
