Depending on the configuration the distribution has used it's likely
expected that ata_piix (which I assume is the driver in question) is
running that drive in current kernel versions. You likely need to update
your boot configuration to point to the correct device. (The kernel
device ordering is not related to what boot order you selected in the BIOS.)
