Yeah, I started the installation as soon as the system booted. The hang started well before the timeout hit and I was able to get the copy to start back up by clicking on the drop-down menu gadget.

I actually have not checked to see if sound works. I do not recall hearing the same music playing after booting to the installation CD that I heard on the MacMinis, so I assume the sound is not working.

Everything else seems to be working just fine, though I cannot set the screen resolution above 640x480.
