No, both a CF card and a FDC shows up as a few 8-bit registers, and both is instructed to read or write individual sectors. Although the command set and register mappings differ, the firmware changes to support it should be rather small, especially if parts of each CF sector is ignored (due to them being 512 byte sector while the firmware might be written for smaller sector sizes). One big advantage of a CF card in comparision to a FDC is that there are no timing constraints forcing you to read/write fast enough. -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
