CF is electrically IDE compatible, but not physically.  It requires an
adaptor, but the adaptor is completely passive except for the power
connector.  I bought mine from from this site a while ago:
http://www.pcengines.com/cflash.htm.  Otherwise, you use CF just like a
regular HDD, no special drivers required.

CF is less than 1/2 the price of DOC, so I have never really understood why
DOC became popular.
