Unable to update my new Yuns

I was following the steps to update my Yuns to the latest, but the example YunSerialTerminal returns errors when I try to upload.

"Arduino: 1.6.1 (Windows 7), Board: "Arduino Uno"

YunSerialTerminal.ino: In function 'void setup()':

YunSerialTerminal.ino:39:3: error: 'Serial1' was not declared in this scope

YunSerialTerminal.ino: In function 'void loop()':

Error compiling.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
"

At the bottom right of the program I see Arduino Uno on COM1

Is this right?

I have a project I'd like to start, but got tripped up right out of the gate.

Thank you in advance for the help!

Welp, I figured out how to configure the Arduino program for Yuns... Boy, do I feel sheepish.

Thanks anyways all. I'm sure I'll have more questions in the future.
