Hello mr. Jeff Garzik,

I had a conversation with Dave Hansen dave@sr71.net
and he confirmed the problem with the Intel SS4200
the ata_piix dont detect the ide ports only ide-generic
and with ide generic is no ide-dma possible.
is there any solution(quirks) out there ?

read from the IDE port after boot.
