Hey Alex, sorry I wasn’t able to work on this for a couple of days.

So, I think the first experiment to try is: build a kernel without “cypide” … just use the fall-back “pciide” driver that will only do PIO, and see if that does any better.

I built one for you:

Give that a whirl… if it results in a working drive (using the slower PIO modes), then that narrows down where we need to look.

Thanks!
