According to the manpage:

Unknown ATA chipsets are supported in PIO modes, and if the standard bus-master DMA registers are present and contain valid setup, DMA is also enabled, although the max mode is limited to UDMA33, as it is not known what the chipset can do and how to program it.

The ata driver can change the transfer mode and various other parameters when the system is up and running. See atacontrol(8).

Take control of the input and you shall become master of the output.
