Log Message:
If setting to pio mode < 3 fails, try to set pio mode 3 before returning
EIO. The spec says ATAPI devices should support "PIO 3 or better".
They are supposed to support less as well. Setting the device to a highter
mode than the controller shoul'nt be a problem, and this is likely what
happens with legaty ISA controllers.
