Since the .vhd image format dates back to the JVC emulator and the emudsk OS-9 
driver, I have been using the same .vhd images that work with the emulators JVC, 
MESS, and VCC. These disks have an OS-9 partition of $5A000 sectors with the 
Disk Basic partition starting immediately after.
Since I also have occasion to mount in Drivewire both .dsk (Disk Basic) and .os9 
images, I use a menu system that automatically runs when I turn on my Coco to 
adjust the Drivewire HDBDOS offset to either $00000 or $5A000 as needed.
