The Intel 6300ESB (aka Hance Rapids I/O Controller Hub) serves as a controller for USB 2.0, UDMA100 and SATA150 devices. Separately of that, there's the Adaptec embedded SATA with Hostraid controller 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 ataraid(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 for 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 played much with changing boot devices. --Bill _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
