No PCMICA card can do DMA. Cardbus can, but there=E2=80=99s no DMA =
defined
in the PCMICA =E2=80=9Cr2=E2=80=9D standard that defines 16-bit PC =
Cards. The CF form
factor in the Z50 is just the PC Card form, not the true IDE form. So =
you
are out of luck if you want a DMA storage option on this card.
