Powercore Express/Mac Pro/Sierra issue?

Powercore Express/Mac Pro/Sierra issue?

Hi all,

Should a Powercore Express (PCIe) V2 in theory work with a 2009 Mac Pro running Sierra with latest PoCo drivers?

I have two FW PoCo units running fine and I’ve just bought a PCIe PoCo as a back up.

The problem is that with the PCIe card installed the OS won’t load and the initial boot sequence keeps cycling over and over never getting past Sierras white loading screen.

When I remove the card the system boots normally and I can use my FireWire PoCos perfectly.

What am I missing here?
