anyway...
it's interesting. Dave and S7 could give better info on this, but I THINK that there weren't so many issues in the transiton from single to dual core opterons, am I right?
That would lead to the conclusion that the problem with this is coming not exactly from the quad-core feature, but from the K10 plattaform itself. In terms of compability of bios, of course, but it's not the number of cores that is the issue.
And that last move would lead to one of the discussions I've read about the problems AMD got: it's worst mistake was to try to push at the same time 65nm, K10 and quad-core. Of course, they had no other option, specially when the initial project from K8Ls were down (if this rumour is true, of course). But it seems that the price of pushing everything at the very same time is still being paid...
