The MEInfo log looks proper. The link will be down if AMT has not been provisioned by MEBx so that’s also normal. Indeed you must use v7 tools, not v8. I would only use Flash Programming Tool from v8 if need be but it’s not like you can’t do your job just fine via v7. Personally I would try to remove all variables. For testing purposes only, I would use completely stock BIOS extracted from the HDR and if the ME might be causing issues, you can disable it by setting the “Reserved” (AltMEDisable) boolean at “Flash Image Tool > Descriptor Region > PCH Strap 10” from “false” to “true”.

43

plutomaniac thanks for tips, and thanks for checking the ME logs too, I thought all looked OK but some I wasn’t sure on and using incorrect tools/errors didn’t help
We still also need to test older 206A2 microcode as well, sometimes latest/final (Since this latest is 2010) blocks ES from working too. Do you have any old copies, in case I can’t find? If yes, please PM or link, thanks!
We may also need to test ME 7.0.xx enabled and disabled too, since there is something changed between 7.0 and 7.1 that Intel is wanting to block people from going back too.

@rustam2v ^^^ That is what I meant about disabling ME, via FITc, this is the Intel Flash Image Tool used to program/change ME internal settings etc.
I will build you BIOS for testing only as plutmaniac mentioned, you will loose serial, UUID during this test, but it’s only to see if disable ME is the issue, or some other issues in NVRAM (Since current NVRAM will be wiped as well)

2nd gen. ES may come without ME. 1st gen. ES may, but for SB or later - no <<< You said, it contradicts itself 1st gen would be SB, Ivy second, and in any ES series for any CPU family there is often several types/versions/variants of ES as well.
And ME or any other feature can be disabled/bugged/broken for any ES, gen doesn’t matter only what they enabled or not in the silicon. And any info you find on ES in regards to features/bugs/errata will be sparse since most/many using ES are supposed to be under NDA and do not often discuss things like this openly.

Here, please test this BIOS, put on by programmer, before doing this unplug all power from the board and short CMOS pins or remove battery for 1+ minute and press and hold power on button or short power on pins for 10-20 seconds, to drain all power from board.
Leave that way with all power drained for 1+ minute, this is to clear/reset ME state, I’m not sure if it’s required when reprogramming with programmer etc, but since you’re having ME related issues best to do it all to be sure.
Then program in this BIOS and test, this is stock A08 BIOS, region pulled from HDR, placed into your E6420_Q64+Q16_fix dump w/ FD unlocked and ME cleaned and disabled.
http://s000.tinyupload.com/index.php?fil…743596442218868

If this works, then next we enable ME and see if still working or not, then we’ll know if CPU can’t run ME.

** Please note ** I assumed this is 6 series chipset, Like QM67, (Not C600/X79), if this is C600 chipset system then do not use above BIOS, let me know and I will build again!

44

All utilities says QM67.
But something goes wrong with windows. It’ became very unstable, and after attempt to return to restore point - only blue screen. Need to reinstall tomorrow to be sure, if this software issue or result of bios games.
By the way, this ES was installed into E6430 with Uma graphics (Ivy Bridge) - it was not start. Display dark, only led blinking. But it normal turned of, with single touch of power button, without long delay.

45


Nah, 206A2 is an ES/QS CPUID so it doesn’t make sense to block anything related to their operation. Well there is only another version which is the exact previous one but it’s not worth your time trying it in my opinion.


ME 7.1 was a different branch, at least initially. It added support for Intel Identity Protection Technology and theoretically OEMs could choose whether to keep 7.0 or use 7.1 for IPT usage. Later on they merged them into one 7.1 branch for simplicity. This is why the “Blacklist” entries at MEA show both 7.0 and 7.1 downgrade minimums. Anyway, that’s beside the point. Basically you don’t need to test anything ME 7.1 vs 7.0 related. For ME related things, I would either test disablement via AltMEDisable or maybe (very unlikely it’ll do anything) just AMT disabling.

46

May be it’s sounds silly, what may means:
“Failed to get ME Kernel Host Interface version …”

47

plutomaniac thanks, all makes sense, nothing more needed regarding what I mentioned. BIOS in #43 has AltMEDisabled Will try AMT disabled next with ME enabled, if AltMEDisabled fails to help.

@rustam2v - did you test this BIOS yet, in post #43? I’m not sure what you’re talking about windows instability, in regards to what, when etc?

48

Just did it, look like we are on the right way. Laptop started without long dark screen delay as it did with this ES before.
Bios setup - OK
F21 boot manager - OK (without MEBx option, as before, as for stock i5 and as for this ES)
Dell diagnostic started with ES cpu, but only multiprocessor cash test, no CPU test )))
Windows 10 boot failed - about 20 minutes with Windows circle animation, then i turned it off.
Now installing pure windows on another hdd

@Lost_N_BIOS Windows instability - because windows spirit gone to heaven, pure install solved this issue )))

49

So you’ve booted with the ES cpu after Lost’s modifications?

50

Yes! Waiting for second one mode.


And hope much, that you explain me more detailed, what you did )))
Very strange CPU, chip too big, to be other than quad-core (inc. 1st gen cpu), it’s same size as 2nd or 3rd quadcore, but CPU-Z report … i3 dualcore, with 4MB L3???

And after attempt to detect VGA system goes to very strange "standby", as Dell diag says, - CPU not detected.
Laptop functioning normal only with discreet graphics.

After some google searching, based on the numbers in the first picture, it seems you have these two CPUs:

1
2
3
4
5
 
912095	Yes	SANDY BRIDGE-M-2	3192-1.2	AV8062701022800Q ACT	QACT	FC-BGA10C	12/16/2010
SR08Q	AV8062701022800	FC-BGA10C	SANDY BRIDGE-M-2	12/17/2010
 
912171	Yes	SANDY BRIDGE-M-2	3302-1.2	FF8062701072400Q AD0	QAD0	FC-PGA10	12/16/2010
SR082	FF8062701072400	FC-PGA10	SANDY BRIDGE-M-2	12/17/2010
 

I can't find anything for "SR082" but searching for "FF8062701072400" does return some sort of listing for an "Intel Celeron B1030" for which no other info exists. On the other hand, "SR08Q" seems to be an early i5-2400 3.10GHz CPU.
52

CPU Chip too big to be anything other than quad core…So needs to find other 25 revisions of 206A2 microcode )))
Another one idea to detect uma graphics, today have no time for this, only most stupid “update driver” from windows, and very strange “standby” after this step.
Tomorrow I’ll try Win7 without uefiboot. It’s more recoverable os for tests )))
@ Lost_N_BIOS Can you explain me or any links to procedure, which you did with this “A08” bios?

53

The size of the CPU does not change depending on its core count. A SNB CPU with 2/4 and another with 4/8 Cores/Threads are exactly the same size. If CPU-Z says it’s a dual core with HT and no TurboBoost then that’s what it is. The other one will probably be an i5 with TurboBoost and no HT (4/4), thus better. Why find other 206A2 microcodes? There is no logical explanation for that.

54

CPU-z can sometimes be showing wrong info for cores/threads if cores disabled for any reason (ie incorrect MSInfo setting, or BIOS disabled cores/not enabling cores etc)

This CPU may not have, or may have disabled, integrated graphics, so you may not be able to use that.

@rustam2v - great it’s working! Now, we do same with A25 BIOS, this may solve some of your current other issues. We should also test ME enabled again, in case the ME or some settings in it etc was messed up before.

What I did was clean and transfer ME into new clean ME file, using Intel Flash Image Tool (FITc) from ME System Tools package from section “C” in this thread
Intel Management Engine: Drivers, Firmware & System Tools
The ME was cleaned and settings transferred using this guide - [Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization
Stock ME as source input file during the transfer comes from repo thread here - Intel Engine: Firmware Repositories
To disable ME via AltMEDisable, you do as plutomaniac said in this post #42 (Do this at end of cleaning guide, before your first save) - Latitude E6420. ME SpiLock failed after CPU change. (3)
Before, or after all that, I replaced “BIOS region” in BIOS with one from Dell HDR

Here is two A25 BIOS with ME version 7.1.80.1214. These have ME disabled in one and ME enabled in the other, please test ME enabled one first in case there was simply some ME setting issue or BIOS region issue previously causing all the problems.

55

of course, you partially right ))) But … Dual core i5 & i7 on left, same size. SB quad-core on the top middle.
So i’ll look carefully, under microscope with multi-tester to look if any hardware difference present, and maybe try to unlock cores and multiplier. I’m old-school overclocker ))) But i’m sure that this 32nm quad core processors naturaly ))) First idea to replace 206A2 microcode with 206A7


I think that A25 bios dump provided before maybe wrong, because it was made on base of @plutomaniac mods + soft flash with Dell flasher to A25. As i found in this case not all parts of bios flashing. As example, yesterday I’ve flashed A25 over your dump and as result have hybrid firmware. Laptop started with this hybrid A25, and ask for cpu microcode for 206A2, after skiping this, windows start booting, but crashed on the way.
Of course, i’ll test with dumps you provided with detailed reports. And i’ll made A25 pure dump before this testing.

56

Sorry, my country under national holidays pressing, so I have no time for test these bioses complex. Please give me vacation till tomorrow evening.
About your bios base on A8, no problem to install w7 or w10, but not possible to activate UMA graphics, after drivers install system reboot and …upsss … dark screen just as drivers loaded. Usual PID_0106. HD2000 or HD3000.

57

Original Dell E6420 A25 dump by programmer
@Lost_N_BIOS Testing ME enable-disable dumps
By the way, not sure if it important or not, but UEFIextract shown special message for both outimage.bin files:
parseNvarStore: file can’t be parsed as NVAR variables store
ME-enable: Boots till first Dell “welcome” choice screen with F1-F2-F3 selection, then keyboard non-functioing … upsss, not possible to select any choice
ME-disabled: Booted with stock i5. It was possible to install UMA graphics driver in Win7. Blue screen after cpu replacement with ES. Halts so huge, that i need to remove battery to turn it off.
Now making “image restore” to Win7 without any drivers. Operation failed.
Tried to zero install of Win7 - failed with same hard blue screen halts
Returning to original A25 with programmer

58

@Lost_N_BIOS What you think about this parameter activation in FITc
ME Region / Configuration / ME / Processor Emulation
This maybe reason of ME fail with ES cpu?

59

@rustam2v - sorry for delays, I’m very far behind lately. UEFITool message is normal, maybe depends on BIOS I used as source, and I checked now and have many files for you here (Some with NVRAM, some without), so some have this message, some do not, and some with NVRAM have it and some do not.
So yes, quite the mess of files we have here, and regarding your flashing hybrid thoughts - reflashing stock may not fix things, some parts of the BIOS are not programmed during flash, depending on how you flash, and some BIOS (Stock) do not have fully populated or both NVRAM volumes, so this creates it’s own issue too.
If you want all fixed, proper BIOS, once we figure out what all works for you. I need your original BIOS dump from both chips via programmer (Or FPT with jumper on or FD unlocked via pinmod), or at least FPT BIOS region dump untouched and original from this system (So both NVRAM volumes intact)
A25 failure at both ME enable and disabled may be due to some of what we discussed above, source BIOS I used. We may need to redo both of those and test again, it shouldn’t have failed on both since A08 worked (Unless Dell put in CPU block list, which I doubt, but it’s possible)

The only way you can return to original A25 with programmer is if you have an original A25 dumped via programmer. Do you have that? If yes, send to me.
On UMA, I doubt that will work without ME Enabled, so for now don’t worry about it until later.

Yes, you may be onto something with the Processor Emulation setting, here is how it’s used (It even mentioned pre-production silicon too)

Processor-Emulation.png



plutomaniac do you think we should change this, do you have any experience with that and ES CPU? If you are unsure I guess we can just test and see.

I have tested with ME disabled and AltM (with ME cleaner). ME disable not always functioning well. But AltM mode functioning perfect.
Also I have test with several option with ME Emulation (FITc). As i found there were no differents, if ME enable. By the way, FITc rebuild not always safety. In case of AltM activation with FITc system not always starts. This depend on bios version. If ME cleaner change only one byte in bios, FITc rebuild making much more, by BeyComp report.
The only problem left is UMA graphics. After driver install OS failed.
I have no ideas why, it’s not looking as locked if CPU itself, but may be locked by intel drivers

Attached original A25 bios dump with programmer
And the modded one, which stable, currently in use
till -7FFFFF = dump of first 64MB chip
From 800000 till the end = dump of 2nd 16MB chip
