RE: Flashboard questions...

To use a SD/CF/etc card requires an ATA interface.

Simply not available on the ROM board or flash board.  That's a whole
different animal.  The ROM/mem board is just that - memory.  The OS does
some magic to make the ROM magically appear in RAM (kinda similar to a
RAM disk - but it isn't).

To read/write mem cards is completely different, and a completely
different circuit and interface methodology.  You can't just unsolder
the ROM, and solder on a connector to put in an SD/CF/whatever card.
