FYI the e800h start address works for SD or DD as the
SD rom appears twice
in the address space at both e800h and e900h.
Not always - I have several different revs of SD controller cards, and I know that
on at least one of them the E900 rom does NOT mirror at E800 - however I also
have several cards that do mirror (which is nice because you don't have to change
the CPU jumpers to swap SD/DD controllers).
