Hi,
just wanted to tell that it could be helpful to skip the scsi update of BB2 (C:SetPatch SKIPROMUPDATES "scsi.device").
It helped on my old system, the A1200 mentioned below, but with a Blizzard 1260 + Blizzard SCSI kit instead. With BB2 installed, the computer would just go into a reboot loop, but after I skipped the scsi update everything worked like a charm.
