There is a quirk patch 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d
"ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge
chipsets(v2)" fixing the 4 ports IDE controller 32bit PIO mode.
We've hit a problem with DVD not recognized on Haswell Desktop platform which
includes Lynx Point 2-port SATA controller.
This quirk patch disables 32bit PIO on this controller in IDE mode.
