Same applies for SB600.
Following patch enables UDMA on ALL IDE devices. The current code enables it only for primary master, which causes my DVD drive to fail under windows install and even after hard reset in linux (DMA seems lockup). The fix should not have any influence for Linux because the IDE driver will correctly reprogram this bit.
