V4SA 2nd IDE Device?

I bought the V4 standalone a few days back, and started to buy &try some additional equipment. One thing I would like to do is to connect two IDE devices to the internal IDE port, so that one can be the dedicated boot-device for the V4SA, and the other one can be a mobile device to go back and forth between the V4 and my emulator.

I got myself a cable with two connectors:

And I have a few different devices: A direct IDE SSD, two different IDE->CF adapters and one IDE->mSATA adapter. All devices work, on either connection of the cable. But whenever I connect two devices the the cable, only one of them is shown in the early boot menu.

I have tried just about every combination of master/slave/cable select settings imaginable, with no change to the situation.

So, does anybody know what the problem is/could be, and can propose a solution? Is this a known limitation of the hardware or the AROS ROM?

How about using the SDcard port as "mobile" device?

There is a general problem that according to IDE/ATA specification, CF cards don't need to support slave mode. And not all CF adapter support it.

Fundamentally possible, but not preferred. µSD-Cards are extremely loosable, and also the positioning of the slot on the V4SA is a bit fiddly.

Yeah, but I have an adapter that does have a jumper for it, so I assume it does support it, but even if not I also have tried the combination of a PATA SSD and an mSATA on Adapter (just to check if the CF card is to blame), both of which definitely come with Master/Slave settings, with no success either.
