Thanks for the information, I am currently working thought the items you 
identified.
There are a few things I do need to correct.
(1) I said that I "saved d0 as d0_emu.dd", what I meant to say was that 
I saved dd and dd_emu.dd.
(2) I am working from a copy of vhd, not the original

Here is a dump of /h0:

Address   0  1 2 3  4 5  6 7  8 9  A B  C D  E F 0 2 4 6 8 A C E

Here is the ident from the 40tkdsdd 3.8.6 floppy that boots to VHD. This 
is the 40tkdsdd boot I made to "test" things. WHen I try to make a 
35tksdss version of the disk (dmode: cyl=23 sid-1 dns=1), it formats and 
is created successfully, but then I try to boot from it (doesn't matter 
if these is a vhd or not, nor does it matter if I am using RGBDOS or 
not), it fails during boot, right after the 6th "." is displayed as part 
of the boot process. It is my understanding that each "." signifies the 
successful read of a LSNO sector.

  80 $F1 $D512FB . Pipe
   9 $C1 $A9E4A4 . Clock

So if I understand correctly, I do not need rb1773.dr in the boot file.
