That shouldn't change much.

I have plenty of SATA and PMP hardware these days, so thanks but that
wouldn't be necessary.

Is the first port occupied? 3726 seems to fail initialization if the
first port is not occupied. At the moment, I'm not very sure whether
the hardware or the driver is responsible for this. When this happens,
all other ports fail too which is consistent with your result.

Ah... So your ATAPI device is connected to the first port. Can you swap
the two and see what happens? Does the same setup work okay on windows?
Thanks for testing.
