It took 5 attempts that time to get to the beastie menu. OK.. unfortunately not really much help except confirming that it is in the BIOS/loader somewhere.. >> Is there an update for the BIOS?

I've always had problems getting gptzfsboot working on this hardware and there are no more BIOS updates now. That's why I have ufs root, as it only worked intermitantly. > Then I wondered what the hell was going on in the loader that took >60s and seemingly touched every drive. I assumed it was FBSD that was tasting all the drives. I believe the loader does look at the drives the BIOS presents to it, certainly at the very least it tries to find something to boot off :) However, even if it is looking on every disk for partitions it should only take a second or so (unless one of the drives is broken I suppose). I have seen BIOSen not boot reliably when external RAID cards are present..
