You'll need either:

a) OS9 LI V2.0 or

b) To hack the BOOT module (if I remember correctly) to start loading
   below $FE00 instead of $FF00.

The problem is that in the coco3, there's a vector page that runs from
$FE00 to $FF00. This is where interrupts are revectored from. This
didn't exist in the coco2's and coco's. Os9 LI version 1.x loaded the
kernel (track 34) from $FF00-1 and down. This would clobber the vector
page. V2.0 of LI booted at $FE00-1 and down.
