That wont fly sadly, if you look closer you'll see that things change =20= from generation to generation of the Promise chips, so chances are =20 very slim it will work. With controllers saying they are ATA of some sort it will be treated =20 as a generic chip, and it should work even with DMA but most likely =20 with reduced performance. Promise chips are *not* in this category... S=C3=B8ren Schmidt sos@FreeBSD.org
