Looks like the sil 3512 is supported with some caveats. Check this link http://www-user.uni-bremen.de/~hburde/solaris_bmc4401.html
and this http://markmail.org/message/gvllasp63xx2z6sv and here http://www.dansketcher.com/solaris-sata-support-for-onboard-chipsets/ The rest i'm not too sure on but once you copy your data off you can reboot and get to testing. Hope that helps -- This message posted from opensolaris.org
