In a similar vein :)

Thank you, but unfortunately, I don't own a Samsung Series 5 550 or a
Series 3 Chromebox, nor any other CrOS device from which to extract a

With respect, I wasn't trying to lecture anyone; I was giving a
straight answer to your question.
I freely admit I'm not terribly well-informed on the subject. That's
why I'm reading to learn as much as I can and asking questions here to
fill in the gaps.

That was my understanding, but thanks for confirming it.

I'm after a couple of things:
- Server: x86, not necessarily Intel, with Core Solo performance or
better, that supports 16GB+ of RAM with double bit error correction
- Laptop/netbook: not necessarily x86, with Core Solo performance or
better, that supports 2GB+ of RAM.
And the kicker is that I'd like both to be fully open! Since no such
systems appear to exist, I'm trying in each case to pick the least
worst option. That *doesn't necessarily* mean running without
microcode updates, so even though you may not agree with them, the
reasons I gave for distinguishing between baked-in microcode and
patched-in microcode were earnest ones. It does mean that I've read
the "supported motherboards" page (for the server) and the X60 and
Chromebook-related pages - plus several other pages - on the Coreboot

I intend to, but first I'm trying to identify the best candidate(s),
because my budget is small. If the C7/C710/HP14 didn't have CPU errata
& corresponding microcode updates, then I'd be tempted to get one for
testing. If not, then probably the X60 is a better option for me.
Hence my questions here :)

Some Trisquel folks are running without microcode updates. I don't
know if anyone except Intel and the sort of security folks mentioned
in Kris Kaspersky's presentation are *testing* anything in relation
to that, though.
Anyhow, since I've managed inadvertently to generate a couple of
slightly tetchy replies here since I started this thread (i.e. yours
and the earlier one from Gregg Levine), maybe that's a hint that I'm
asking too many questions or something, and that I should take my
leave for now?
Thanks again for the help you've given,
 I don't have a fixed understanding of what I mean by "least worst
option". Each time I learn something relevant, I try to update my
