MSI K8MMV with the K8T800 & VT8237R chipset.

>Description:
I created a RAID1 array with 2 SATA disks in the BIOS and then booted into 
FreeBSD which thought it had a few extra disks (but works fine).

[midget 21:46] ~ >sudo atacontrol status ar0
ar0: ATA RAID1 subdisks: ad0 ad1 DOWN DOWN DOWN DOWN DOWN DOWN status: READY

I did boot verbose earlier and found that the dump of the metadata descriptor
showed non-zero disk IDs in all slots (that wasn't logged but I can reboot if
you need it)

>How-To-Repeat:
>Fix:
Unsure, it IS just cosmetic but it may not be for other RAID types (eg RAID0 or
RAID5).
