VIA 8237 RAID

[Franco Bruno Borghesi]

Has anyone tried any VIA 8237 RAID motherboard?

I've just bought a MSI K8T Neo with 2x80GB SATA 150 disks. I've created a 
Raid 1 configuration from the BIOS, but when FreeBSD (5.4 for x86) CD boots 
it detects both disks (ad4, ad6) and installer allows me to partition both 
disks individually.

I was hopping to see a single 80 GB drive from BSD. Could anyone give a 
hint?

Thanks in advance.
