While that's not optimal, it wouldn't be a first.
No, that would be unmaintainable. The best solution to me seems to be to make SMBASE programmable from non-SMM code if some special conditions hold. Michael, would it be possible to get in contact with the Intel architects? Paolo -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
