Hi
Does the controller have ROM on it? Often the image
on the disk has to match with the ROM. Sometimes
the ROM only has a minimum boot code and the disk
loads the rest of the disk code. Other times, the ROM
has all the disk code and the disk is just the rest of
CP/M that calls the ROM for disk access. Yet other
are mixed with patches in the disk code.
The exception is for a controller that does DMA and
self boots, like the Digital Systems drives( no ROM in
the system ).
