Well, here is how I have VCC setup and it is doing what you want.

  The .vhd image is the one I normally use with MESS. It is stocked with 
the latest NitrOS-9 LevelII 6309 code and has the kernel and OS9Boot 
file on drive#254. The AUTOEXEC.BAS file on the .vhd drive#0 consists of 
10 DOS254.
  VCC has the FD-502 controller mounted in MPI slot#4 and the hard drive 
controller in MPI slot#3. The MPI controller is set to slot#4 and the 
FD-502 controller is configured to have the RGB-DOS ROM. This is all 
done from the VCC Menu bar.
  On a cold start or hard reset (F9), NitrOS-9 automatically starts.

As it turns out, even if you just have the hard drive controller, 
harddisk.dll, mounted in any MPI slot and have the slot selector pointed 
to the hard disk controller, you will be using RGB-DOS and you can still 
boot NitrOS-9 from the hard drive.

The clock used in VCC (see the pdf file) is the Dallas DS1315 also used 
by Cloud-9. You should be able to find the clock2_cloud9 module on the 
80 track release disk in NITROS9/6X09L2/MODULES/CLOCKS. If you are 
trying to use my swread and the clock2_soft you will need a version that 
works with the DS1315 rather than the SmartWatch.
