Hi,
for the record: I had the Q9000 (not Q9100) running in my Thinkpad T500 for a
few weeks now without microcode updates and did not encounter any issues so far.
Cheers, Daniel

It varies as per CPU revision, some have newer/older onboard microcode

You won't know until you try it, or someone else with the exact same cpu
model/revision posts back (might take a long time)
I would check the errata spec sheet to see if there is anything bad that
is addressed by later microcode updates post-your cpus onboard version.

Hi,
I am considering upgrading my Coreboot'ing Thinkpad T500 with a Core2Quad
Mobile Q9100 [1] (which requires some hardware modifications but is doable). My
question is: Does this CPU require the microcode updates or will it run
without? Practical experience from someone running this or a simular CPU from
the same family (Q9000, Q9300) would be appreciated!
Cheers, Daniel

Just because you appear to have no problems doesn't mean they aren't
there, see the opteron 63xx microcode bug from a year ago that allowed
programs to obtain root.
