[Coco] partial OS9 boot from hard drive (back on topic)

[Robert Gault]

Vern,

Could you email me copies of your cc3go, init, and dd as set for a hard 
drive boot? I'd like to take a look at them with dEd.

By the way, is there a startup file on the hard drive? If there is, try 
renaming it to something else and retest the hard drive boot.
