The CFFA3k will insert virtual ROM in the slot you tell it to.  So, if
your card already has ROM in that space, they'll collide.

In the GS through the control panel, you can configure a slot to
either behave with the internal definition or instead to obey what's
plugged into it.  In order to get the CFFA3k's virtual Disk II slot
working, you have to set that slot to "your card" so the ROM can be
inserted in that memory space.  If there's a physical card in that
slot already, it wouldn't work.  So I think the short answer to your
question is, "no."

But it's endlessly configurable... you can set the CFFA3k to emulate
the Disk II in the slot that the '3k is already occupying, too.  It'll
disable the SmartPort drive capability, but it's possible.
