(updated the email addresses of various recipients) Sorry for digging out this old thread, but I can't seem to find supporting evidence for this, at least described in a in-your-face way.. Can we determine whether the RNG generates pseudo-random numbers based on a version number, or some other register? Would RNGv3.0 be a good check? I see that today we describe kodiak and talos marked as having a TRNG, but they're much much older than 8450.. Konrad
