I have just (I think) installed the new firmware into my 990.

Excuse my ignorance but what is the most obvious indicator that I have the new software installed?

To me, it appears nothing has changed. For instance, activating the 7.1 direct input from the front panel-how is this done?, by cycling thru- pushing the input button? I have tried this and I can't seem to input 7.1. This leads me to believe that the install failed. Same with renaming the audio inputs and also the surround modes on the front display. It all seems to work the same way as before.

Thanks in advance for any input
