(US15W, US15L, UL11L) PATA controller support.
From the Intel's documentation I got the impression that the part numbers start with AF82 (82 being the usual Intel's chip number prefix).
From documents I got, no 82xxx part number assigned. The formal names for SCH are just like US15W, US15L and UL11L.
Look into the spec. update, "Identification Information" section.
You shouldn't enable prefetch for ATAPI deives I think -- look at what ata_piix does...
Why?
Prefetch usually doesn't work with ATAPI devices since the prefetch logic operates in units of 512-byte sectors and not all ATAPI data transfers are a multiple of 512 bytes.
