32-bit acorn hardware • Abort on instruction - RISC PC - IanS 16bit IDE Podule

Trying to figure this out...

I bought an IanS 16bit IDEFS podule a while back and it has been working great in my A5000 for months. As my Risc PC original hard disk is starting to show signs of giving up, I thought it would make more sense to have this podule in my RISC PC. viewtopic.php?p=454533#p454533

As a consequence of a number of moves I lost the podule backplane on my Risc PC, so I ordered a replacement from CJE, which arrived today, and installed it, along with the IanS podule.

My Risc PC has no CMOS battery in it - which has never been a problem, simply power on with the delete key (pointing this out just in case).

Now with the podule fitted, I get the following error on boot:
I can still get to the desktop, and if I
It shows the IDE Interface - ZIDEFS (16 bit) in Expansion Card 1.

There is no ZIDEFS modules loaded though, and no configuration options available either, so I can't do a *configure ZIDEFSDiscs 1 or anything.

Anyone have any ideas what I should do?

If I remove the podule it boots fine (as it always has done).

Thanks
David
