Maybe in this case FreeNAS is just on flash, that seems the normal way to install it. You said sas2ircu saw no adapters, but I think you probably need to use sas3ircu for this model of HBA. Another quick test I suppose might be to boot with current NAS4Free - whether you want to use that or not, it's based on FreeBSD 10.2 so you might see some different behaviour. Though a FreeBSD 10.2 livecd/liveusb would achieve the same thing. Graham --
