I will try ripping out all my SCSI over the weekend and see if I can also get a working SMP system that way. > BIOS, I assume that's theoretically possible.

That's the preferred path I think - I'd also like to see if this is SCSI in general or just Adaptec SCSI. As I also have a ciss caard in my machine I will try it both ways. > I'm not sure which list fits this best; there's not really a good list for > "anything happening on an Opteron whether or not it's in amd64 mode". I have been thinking about this - it's probably not the Opteron per-se, bbut the chipset used to support it. What chipset is used on your motherboard ? -pete.
