    The compact flashes appear to PCMCIA as removable IDE drives.
    Unless the PCMCIA-CF adapter is more than just two connectors
    plus a set of wires in between, you should have no problems
    at all. Either IDE, or IDE_CS driver should do it.
    (The IDE_CS will, of course, need the PCMCIA suite too to
    support removable media. IDE doesn't support removability.)

    To boot from CF you need support in your boot-rom/flash
    code. Something which might not be true, unless you write
    it yourself..
