[Coco] Trouble booting NitrOS9 under MESS 148

Bill,

I have run link.bas but that didn't make any difference.

I'll try again with a 35 trk disk.  I was using an 80trk and a 40 trk. I wasn't aware that was required.

I do eventually want to setup DW/Becker but my goal is to get a bootable vhd running first.  Rgbdos seemed the easiest way to go.

I don't recall it being so difficult with my real coco 3 and Burke&Burke interface 20+ years ago :)

Thanks for the suggestions!

Philip
