Did you mean the discussion you and I had?  That was about OUTS, not LODS.
You showed by running code on various machines that newer Intel cpus
don't support a segment override on OUTS while older ones do.  I was
rather surprised, especially since older Intel documentation said a
segment override was supported for OUTS.  Newer PIII docs say it isn't.
