Take a look web page . They're saying:

1) remove C30 (I did not install it and did not jumper it)
2) add a 690 ohm resistor from the top of C30 to +5v on the proto area.

For internal links, they show:

1) jumper TSEL to OPTOOUT (I've done that)
2) jumper TACHSELECT to XG1 (I have NOT done that)

I still have XG1 jumpered to XG2 as called for in step 52.

Here are pictures of the top and bottom of the board:
