Compact Flash socket info?

[Shdwdrgn]

I've been trying to find a sample schematic of how a 2-slot compact flash connector would be wired.  I am assuming there are 1 or 2 lines specific to each connector that act as an enable for the card plugged into that connector, but I can't seem to locate what I'm looking for.  Does anyone know specifically which line(s) act as the enable on a setup with more than one socket?  Would it simply be a matter of connecting all the other lines directly from one connector to the second, using a seperate enable line from the controller chip, or is there something more to it than that?

That's typically how it's done ... as long as the controller or CPU interface has enough drive capability for both loads.

I found a reference in some conversion sockets between CF and PCMCIA which suggest that the master/slave designation of each connector is specified by /CSEL (pin 39 on CF).  Low=Master, High=Slave.

Can anyone verify this information?  I see on the zaurus that this pin is left disconnected, which may put it in a cable select state.  If this is true, I should be able to wire up a second port, and connect pin 39 to either ground or +V.  Seems way too easy, but then again that's what I thought about the external battery packs I'm testing, and they're doing fine... so maybe I'll get lucky again.
