Hi Hans,
I'm sorry, I don't know how to build it.
I've tried, in the mean time, to boot it with freeBSD, and it boots and can see the disks, but it uses mr_sas as driver I'd say.
Could it be that freeBSD's mr_sar has this status ?
In any case, if you can build me an ISO it would be great.
Thanks.
Maurilio.
