Also, I had seen questions about how they did the front panel. It is pretty sweet. The whole thing is basically just a 4 port hub. This is attached to one of the mobos USB headers. Attached to the hub is a USB keyboard which is used by the front panel buttons, a bluetooth adapter, and two left over USB ports. The IRDA sensor is also on this front panel, but it looks like it is just routed the mobo's IR header. All this is built on a custom PCB. this is very similar to an Xbox mod I did, where I broke out one of the controller ports (number 4) to a small 4 port hub, installed 2 USB ports, and a wireless keyboard and mouse receiver.
The eTDVD bios is just a bigger bios chip installed with the playnow! extension. I haven't played with this DVD player much yet, though. I was hoping that it wouldn't boot into it at all if it didn't sense a DVD or audio CD, but it always boots into it first. It does have an adjustable time out to boot to OS without user intervention, though. I set mine on 5 seconds.
Oh, and you can turn off the etDVD bios so it always just boots normally.
