Yeap, there is a layer, but it still needs low level support. > So to be clear, there is not yet any support for my configuration > (sata_promise+SiI3726) in any of your code branches ?

You can try but the biggest obstacle would be lack of=20 document. If you can access the doc, it shouldn't be too difficult, I=20 guess. You can analyze how sata_sil24 has been changed and update=20 sata_promise similarly. --=20 tejun
