Okay, I tried that, and I'm getting I/O Errors. Hmmm.

I just had a thought. What if I try writing a Basic09 program that mimics
DSKINI? If I'm having trouble making a workable boot disk using DSKINI,
why don't I try sidestepping DSKINI by writing a Basic09 program that
does the same thing?

Using my PC I could save the .dsk image to a 720k 3 1/2" PC disk, and
then copy the file over to my Coco's hard drive using the PCDOS utility
on my Coco. From there Basic09 could access the file, and copy it
block-by-block over to a newly-formatted 5 1/4" disk. What do you all
think? Could this work?
