The Intel 6300ESB (aka Hance Rapids I/O Control= ler Hub) serves as a controller for USB 2.0, UDMA100 and SATA150 devices= . Separately of that, there's the Adaptec embedded SATA with Hostraid c= ontroller driver which comes into play if you activate RAID in the BIOS.= Since they refer to it as Adaptec's Hostraid controller, it looks like a= taraid(4) should support it. And Nooooo, I didn't have ataraid defined in my kernel. It was, but for= some reason it isn't now. I'll uh, have to add and rebuild. Thanks fo= r pointing out my error. Now, when the ar0s1a-f devices do show up, does the boot device actually= get changed from ad4* to ar0* or do I need to boot single user while it= 's talking to ad4* and change the mount points and reboot? I've never p= layed much with changing boot devices. --Bill
