I'm not sure if the files on the Yahoo group are current or not.  I
can send you that last version Gary sent me, which may be more or less
recent than what you have.

In general steps, you must:

1. Load the CoCo 3 ROM at address 0 of the flash
2. Load the .sof into the board using the programmer

That's really it.  I've heard you only need the .pof if you want to
make the board start up in coco3 mode, I've never tried that.

Switch settings of 0,1,2,3 and 7 on, rest off works here, I forget the
purpose of all of them but 0 and 1 are the CPU speed control, and 8 9
are the serial port speed control for drivewire, off off is 115k, off
on is 230k, on off is 460k, on on is 920k. 115 and 460800k are tested,
920k probably won't ever work.
