I have been trying to get the xenium people to open their mouth about this in ther own forum. Here is what they last wrote.
QUOTE
I am not a member of the Xenium hardware development team, but everything that I know about the chip, the way it works, official words from the team, etc., you do NOT have to install a resistor with the Xenium ICE on 1.6 or any Xenium (ICE or blue) on <1.6. I will mention a note to the dev team to respond on this thread. I could be wrong...I don't think so, but if I am, then I'll get to learn something too.
Now I am looking forward for a respond from the hardware team...
