Probably not, the formatter contains the relevant table for the drive 
configuration, not the ROMs.  However, the ROMs do contain diagnostic 
and formatting routines, which are invoked by a special set of commands, 
distinct from normal MSCP commands/routines, and it may be that the 
oldest ROMs don't have something needed for later drives like RD31 etc.

You mean which DEC names match which drives (RD31 is 20MB ST-225, RD32 
is whatever is 40MB, RD33 is 65MB) or how to invoke the right stages of 
the formatter?

Yep, that's about it, as far as I remember.  A log would be useful as a 
record and aide-memoire, though.
