The actual RAID is done by drivers; onboard RAID is actually software RAID with a minor RAID BIOS which can write metainformation about the array configuration and has BIOS bootstrap support. This is also called "fake RAID". FreeBSD does support some fake RAID metainformation though, by reading the metainfo from the disks and assigning it's own software RAID-mechanism to it. For information of which metainformation formats are supported, checkout the ataraid(4) manpage: http://www.freebsd.org/cgi/man.cgi?query=ataraid&apropos=0&sektion=4&manpath=FreeBSD+6.2-RELEASE&format=html If your fakeraid is called "Intel MatrixRAID", then yes FreeBSD does detect the metainfo and you will have a "ar0" for your first fakeraid array. You should be able to install (and boot) from fakeRAID since there is BIOS bootstrap support. - Veronica
