They shouldn't be in PIO mode, they should be in DMA. I don't see what he sees however that makes him think think they are in PIO. You can't tell from those screens.
They now run at the same speed? Fast or slow?
You are correct. I didn't notice that a couple lines below the PIO Mode 4 there is another line that reads Ultra DMA Mode 6.
OP: you will need to see what mode the controllers are running in via the device manager. Since most devices no longer use PIO, it is probably safe to disable it in the bios, although auto shouldn't hurt.
