Yep! That one worked! I copied my coco's boot disk(720K 3.5) to an image and 
it booted in mess. But I neglected to remember that this used ddh0.dd and of 
course, it didn't really work once os9 began looking for the hd. DOH!
 So started over with a boot I use on a floppy coco(720K 3.5). vimage got 
part way through and errors out with a 203. Bytecount A200
 I tried an original os9 L2 disk(backed up to a 3.5 ss35trk) and same error. 
Byte count 1200

 dcheck shows no errors(for what that's worth) Both disks boot and work 

 Any ideas?
