Changing the metadata format between BIOS updates seems pretty scummy and obviously if FreeBSD expects one format and you have some other format, it won't work :-( However, I believe the sil3112 has problems beyond this and is just a bad controller. Here's a reference from sos@ who wrote the driver and knows what he's talking about: http://lists.freebsd.org/pipermail/freebsd-current/2005-January/045274.html Good luck, --Alex
