Silicon Image Sil3114 Hardware|Bios RAID1 from AMD64 LiveCD?

[chi-z]

Is it possible(yet) to set up a hardware|bios RAID1 up with Silicon Image Sil3114 (SATA)?

I've google'd and searched these forums, but found nothing but how to set up a software RAID1(via /dev/md*).

In the bios I've selected RAID1, but gentoo sees a /dev/sda and /dev/sdb = no RAID1 w/ out software raid'ing.

Thanks in advance to anyone that can provide some help...
