You shouldn't need to have GRUB on the DoC to support multiple partitions.  
Grub is simply the bootloader -- the MTD/DoC stuff should work the same 
regardless of the presence of GRUB/LILO/whatever.

Use the GRUB firmware if the DoC is the primary non-volatile storage in your 
system.  Off-topic, but if you have a MBR in your target system, what is the 
DoC used for?

I have not found a reliable way to use DFORMAT to load the Grub firmware.  

In general, DFORMAT is only needed once (to install M-Sys firmware version 
4.2), and doc_loadbios is used to install GRUB.
