it seems that this one does, but it's important for any CF
adapter to support DMA, and for your CF card to support it as
well.  i just upgraded from non-DMA CF to one with DMA, and the
read performance went from 5MB/sec to 15MB/sec.

note that there is a set of cheap adapters out there labeled as DMA
which are _not_.  this is the one.  note the attractive price. ($4.99)

(i found out the hard way.  i was able to add wires to enable
DMA, but it required equipment at work -- i couldn't have done it
with my home soldering iron, or without a magnifier.)
