The problem is that the RAID metadata isn't identical for all motherboards that use the same SATA controller -- it is dependent on the BIOS also. For instance, I have an Iwill DK8X that has a Silicon Image 3114 controller. On many motherboards using the SiI 3114 FreeBSD knows the RAID metadata, however on this motherboard FreeBSD doesn't -- because my BIOS does things differently than other motherboards with a SiI 3114. -- -- David (obrien@FreeBSD.org)
