I have last few quesitons;

1- What if i flash stock bin, what i'm gonna see at dxdiag "System Model" ?
3- When people uptade their bios with orginal update software, so i guess flash software does not write/change model number bits? ( Because you saying stock rom has no model number there like OEM)

2- Why E5-571G-57D9_LA-B991P.BIN NOT working on my computer?

3-Can you send extracted.BIN file pelase?

4- I may find a friend from local forum that he using same computer with me and factory bios, if i ask him to backup his bios, "fptw.exe" able to backup whole 8192kb bios? And what is the fptw parameters for this?

I don't need mod my bios, i don't need advanced settings yet, but thanks for asking.
If you mean correction model number like just editing "v3-572" string to "E5-571" i'm able to do that with HXD.


Finally, actually you saying i don't need to do anything it's already coorect BIN i'm using?

1. If you "Flash" a stock BIOS that is fine (via exe), if you program in a stock extracted BIOS file with your programmer then you will loose all current board specific details (NVRAM volumes, Serial, UUID, windows activation, and possibly LAN MAC ID)
That is why I said don't do that initially, I was going to copy all that into a stock BIOS for you and still can if you want, then it will be OK to program back in with programmer

2. Yes, stock BIOS update methods/tools know to ignore/not flash certain bits in the BIOS so it does not overwrite certain things, this is done by programming.
Often in these places in a stock BIOS there is either FF or 00, or sometimes generic data like 0123456789ABCDEF etc, and during flash this is skipped over because it knows the leave as is so stock details are not lost.
Sometimes, certain flash methods, not stock intended for whatever system, such as programmer or FPT flashing, will overwrite this data with whatever is in the file, and that is why you often will see people complaining about updating a BIOS and loosing serial or loosing MAC ID etc (incorrect flashing method used for the BIOS source used)

So, I was correct about MAC at least being in that same location, it's in the previous image I showed you on post #15 with the rest of those details


3-1 - I don't know what you will see if you "Flash" stock.bin (run stock Z5WAH132.exe I mean). If you program in a "stock.bin" file without editing it, I assume all details would be blank, serial, UUID, LAN MAC ID etc (Could be FF or 00, depending on where tools pull the info from)
And, as I mentioned previously, there may be other locations in the BIOS that does contain some stock model strings, I didn't have time to dig that deep. If you "Flash" and those are used for some things, your current model ID would be left in place anyway, so nothing would change.

3-2 Extracted.bin file is the stock BIOS extracted from EXE, then extracted from the BIOS.fd file (9.63MB) the Insyde flash tool (H2OFFT) use which contains the BIOS image and 3 other "image files" (driver, INI files to control how the flash is used, EC FW)
This is what I said you should not program in because you will loose all board specific data, so it's not ideal at all for me to give you, but if you really want it I can send?

4. Your friend, either has unlocked FD himself before this, or the FPT dump he dumped is not complete, size would still be 8MB just would not contain all of the actual regions on the BIOS chip.
Since stock BIOS has locked "Read" of the ME region, so he shouldn't be able to dump a complete BIOS with ME inside it too unless FD unlocked/bypassed.
I suppose there may be instances where this gets ignored, but it's not likely, he probably unlocked the FD first via pinmod or someone programmed in an unlocked FD, or he used some other method to temp unlock FD first and either re-wrote it unlocked or dumped the entire BIOS while it was unlocked.
FPT is very easy to brick your board with, at least you can recover with programmer, but still be careful using it unless you know what you are doing or have asked what command to use and what files to give as source.

FPTw.exe -d bios.bin << That will dump entire BIOS if FD is unlocked, otherwise it will give you error, or dump full size file but skip the locked regions (in this case ME Region)

I meant I can unlock the hidden BIOS menus for you, and yes I could also edit the model ID to be correct as well. I am not sure if straight hex edit on that file as a whole would be OK, you should extract the padding file it's contained in with UEFITool, edit that, then insert back and rebuild, so any checksums get corrected.

Yes, you are using correct BIOS, both boards use exact same hex matched BIOS file, yours just has incorrect model ID inserted either by mistake or they used some other dump to straight program in like you mentioned at post #3.
And if they did that, they either didn't check that info and left it as-is (So some other system out there has same), or simply forgot to edit the model detail but corrected everything else, or the source they found gave incorrect details and said "here is 571G" and they didn't check and it was actually dumped from a 572G board
It's hard to know what they did or why, but they weren't the best techs if they didn't backup the BIOS first and give you a copy in case needed, that should be any techs first move, even if it's a corrupted dump

Hello again @Lost_N_BIOS.

First, thank you so much for your all clear and nice answers number by number.


After you said, i feel i want to use that bios i already have it. I decide to use this bios (v3-572 but its the same 571g). i want to use lastest version of this bios i already have. For now, i just only update my bios with Acer orginal uptade software. ( I tried verison 1.27, 1.13, 1.32 ).

Anyway after i run original uptade software couple times , now i have a problem with my GPU (Nvidia 820M). In the device manager it says "there is someting error and this device is stopped.) When i check nvidia with CPUz kind software, it says Bios version: Uknown. Clock frequencies: N/A

How can i fix that?

@nmb - Sounds like whatever BIOS you flashed in was not the correct one for your board, didn't have the correct vBIOS module for your graphics card, or some ID/Flag detection during the flash loads the wrong one due to the current BIOS ID
You mentioned the vBIOS before I think, or at least you noted one system has xxx GFX card, and the other has different model card. Since both system BIOS are exact same (the ones I checked anyway), I can only assume some check compares the model ID or some other ID and then loads it's respective vBIOS module.

To clarify something you mentioned at post #16, I never mentioned anything about v3 BIOS when I compared BIOS to yours. I compared your dump, and then E5-571G and 572G stock BIOS, which were hex matching, V3-xxx has nothing to do with anything I've been discussing.
V3-571G is totally different BIOS, not even same size or type of BIOS, so I can see that would be an issue, since you have a E5 System not a V3. Flash back V5 BIOS

@Lost_N_BIOS I can not use my hardware programmer, when i try to flash new bios chip, i have some issues my computer never boot up with new chip, even the file i dumped with programmer at my friends home(my old chip v3-572g) (We can say i'm cloning my bios chip, and my computer does not even boot up with the clone chip, maybe there is USB hardware programmer issue, not sure. But i can say it's working fine, because when i read chips i checking rom with hex editor. Everything looks fine, erasing reading writing verifying.. ) my computer does not boot up, so everytime i had to solder back my original v3-572g chiP to start up my computer.


Couple weeks ago with this bios (the wrong one v3-572g) i can use my GPU. Sometimes i update bios etc (while try to install 571 bios)i got driver problems, but i can fix it with edit driver ini etc.

But now, i have bigger and completly different problem.

I had some issues with my GPU but it is NOT driver problem, Now VGA BIOS VERSION: unknown . Couple weeks ago the same bios and same versioni'm using right now, i was use my GPU with not problem ( only editing driver ini files, i can able to use it with no problem ). But now, it's tottally different issue, like even CPUz can not see bios version and memory and clock of my GPU.

FLASH BACK V5 BIOS? you mean E5?

I never talk abuot V3-571 i already have v3-572 why you mentioned about it? to tell, and an example bios difference?

How can i flash back E5 bios, It's the reason whole topic i started. How can i do that? I never have original E5 bios. I never backup it.

Btw i find a trick editing FD file and perform ini, and giving write access to bios (bios version 1.31 has an exe WRWEC.EXE, there is setup.bat files that with this exe you having write access after restart, it's someting like;

WRWEC 59 7C >nul
WRWEC 40 84 >nul

restart computer then;

WRWEC 59 7D >nul

After i gain write access, i can flash any version of FD file ( i'm downloading e5-571 page of acer ) .


now i can flash any version bios to my computer ()(even if i download 571g FD file, after uptade it still says v3-572) "Like you said some bit's never written" ... Maybe you can import E5 bios you talking about to FD file than i can try to flash it with insyde sotware write access?

And how we can fix this GPU problem now? Becasue even with wrong bios, i remember i can install drivers with editing nvidia driver ini files.

But now, editing ini files or try to install older fermi nvidia drivers NOT working. I see this;


My GPU is GT 820M 2GB NOT 1 GB

I FOUND THIS PICTURE ON INTERNET ;

Not being able to write BIOS and boot, means you are not writing BIOS properly, or more accurately the software you are using is not verifying the write properly, or the file/BIOS you write to the chip is not a complete BIOS.
Do one test for me, write some BIOS to a chip with programmer, then dump it with programmer, then send me both those files (The source, and the dump of BIOS after you program it to the chip)

Yes, I meant E5, sorry for any added confusion

I've never looked at any V3 BIOS during our discussions here, only E5 BIOS, since you said that is your model.

If you can write to FD, without programmer, then unlock FD and make sure to never write FD again, then you wont have to use programmer anymore and can use Intel FPT instead easily
See spoiler #2 here, image #1 - [Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing
Once you have access to the FD (ie you unlocked it with your method), take FPT and dump the FD >> FPTw.exe -desc -d fd.bin
Edit that per the guide above, then flash it back >> FPTw.exe -desc -f fd.bin
If you do not understand how to edit the file above, send me the fd.bin and I will edit for you.

Only way to fix that V3-572 is to write this area (BIOS region) with FPT or programmer (entire BIOS write when you use that)

FD is a tiny region of the BIOS, at the beginning of the BIOS Chip (or start of a complete BIOS dump) Once you unlock it, and then write in the unlocked FD as I mentioned above, then yes, we can fix this V3-572 via FPT flashing of the BIOS region with mod BIOS.

GPU issue I cannot help you try to resolve until the correct BIOS is on your board, otherwise it's pointless to try and fix. Editing drivers are not part of this issue or resolution, however you may make things worse by editing drivers

I dump 4kb data with FPT, then i edit the file with HXD and change bits to FF. And re-write it with FPT. so i guess i unlocked it?

So what is next?

By the way, i was talking about the BDW file i can write is comes from unzipped Z5WAH132.exe BDW.FD 8mbye, i was NOT talking about the 4KB fd file from FPT.


Edit:

PDR Region does not exist.
GBE Region does not exist.


is this a problem?

PDR/GbE error is normal, not all BIOS contain those.

Yes, if you edited FD correctly, then you now have unlocked FD and can write entire BIOS or BIOS region via FPT without issue however, that should normally be the case anyway for BIOS region (BIOS region almost always unlocked, usually only FD and ME region locked)

You cannot write the BDW file with programmer, is that what you were writing when you said "It fails with programmer every time"? This file is 9.63MB anyway, too large to fit BIOS, so I assume maybe you notice that and cut out the actual BIOS?
If not, that is what you need to do first with the BDW file. Actual BIOS from BDW file starts at CC0 in hex and is 800000 hex bytes in length, from CC0 to 800CBF is the actual BIOS file (Stock)

What is next? To me, next and originally suggested thing is for me or you to edit your original dumped BIOS and program or flash it back in, all that needs changed is the DMI data I originally said they manually inserted incorrectly.
With unlocked FD, you can do this with FPT, be sure to unlock the FD on the new edited file if you flash entire BIOS (FPTw.exe -f bios.bin), or just flash the BIOS region since this is all that's needed once you make the edits (FPTw.exe -bios -f bios.bin)
This is inside second main padding file when BIOS viewed with UEFITool, extract that padding file and edit in hex at 25000-25150, or if looking at the entire BIOS file in hex this block of data starts at 235000h

@Lost_N_BIOS , bro like i said, i don't care UUID and other MAC ID or model number things. I need to fix my computer. If i edit my BIOS file changeing just ID's gonna fix my GPU problems? And if i edit my bios, i'm gonna edit my wrong bios. I need correct E5 bios? Where can i find it?


Your another post you saying flash back E5, now you saying edit V3? Can you tell me to how can i fix my computer properly clearly?

My biggest problem is my GPU right now.

I understand bro! Yes, and yes. Fix your originally dumped BIOS, GPU was working then!
The BIOS you originally dumped and send to me, was E5 BIOS, as I've told you, edit the DMI info and you're done. See second image here, page one post #15 Dumping bios with SW / Programming with HW.
V3 BIOS is not the same kind of BIOS at all, it's not even the same size 5.1MB BIOS region vs 6.14MB BIOS region and 6MB total BIOS size vs 8MB

No, I never said edit any V3 BIOS, nor had I even looked at any V3 BIOS until the other day when you mentioned you flashed one in for some reason and then having more issues, I said edit your originally dumped BIOS, change the incorrect V3 entry to E5 info.
I've said this exact thing since day one right after I compared the BIOS files, but you didn't believe me so I can't really help you much more other than this until you start believing me and doing as I suggested

@Lost_N_BIOS ,
i used h2osde-w, it changes DMI info but, after restart, old values comes back. Can you edit DMI for me ?

Yes, dump complete BIOS again, with programmer if you are not writing back complete BIOS with FPT. Then tell me what you want changed to what.
