Ron, any (practical) example of above described practices? I have in my
laptops here 6 x 4 GB DIMM modules and 2 x 8GB DIMM modules, all of them
have SPD mounted.

this?

Just waiting for you, Michael, to try it. All the possibilities we
lamented here, you got/have several proposals to try practically, and I see
it as very good learning experience, and understand more. I offered you one
SW method to try, you have original T400 boards with original BIOSes, you
can even buy flash chip with original BIOS (and you can also try to combine
proposals, also experiment). Several possibilities, one full 10 hours' day
of hard work (maybe two days, if you take it easy).

And, Enrico (although email is signed as Florian ?!) also wrote an
excellent email, with some very good explanation how BIOS descriptors and
regions look alike in T420 (I bet, it could be very useful).

Being you, I would roll up sleeves and start working... Trying various
proposals practically/empirically!

My two cent opinion! Peace. ;-)

Best Regards,
Zoran
