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..
