This package hasn't full BIOS dump.

---

I'm not interested in that.
The BIOS-file in this packet can't be flashed by usual methods.

Hello Fernando,
my dell optiplex 9030 AIO motherboard has 1 slot for m.2 2242. I installed m.2 2242 nvme 2242 into this slot and it is recognized in windows disk manager, I can store the data on it. However, the original bios does not support booting from nvme ssd, I want to modify the bios by adding the NvmExpressDxE module as you described above. The problem is that I cannot extract me current bios (using AFUWIN64), and the bios exe file downloaded from dell cannot be converted to rom file also. Could you please help me to make the bios rom file for dell optiplex 9030 aio?

when i extract dell bios .exe of xps 13 laptop found mismatch bios region 5568 kb only while it should be 6144 kb according to old bios backup.
i tried all .exe package of this model which are available on oem website but problem are same.
so i decide to make new bios with 5568 kb bios region via fitc .
i made it simply with new me region & 5568 kb bios region without any error.
now drag made fresh bios to me analyzer it seems okay.
i flash it to spi eeprom but get no display.
i analyze my old bios region & extrected bios region here are difference only i see that fitc added 589824 byte FF offset to make bios region 6144kb.
its the problem.bcoz bios rgn should be same as old bios.
i tried to replace bios rgn with uefi tool but its gives me error bcoz size was mismatch.
IS this problem of DELL BIOS EXTRACTOR script or something other problem.
i am uploading here old bios dump(working) with pic of laptop service tag.
what are the possibility to solve this type dell bios.
thankyou

@earthoo7 - please link me to the Dell download page for the exe you mention. Usually, you cannot use extracted BIOS from files like that in an easy manner to fix a BIOS, it's often HDR or other partial BIOS region formats or volumes etc and can only be used in a manual rebuild of a dumped BIOS or BIOS region etc.
If FPT dumps BIOS region 5568K, then this is size of BIOS region. How did you make the 6144kb backup, maybe it was not with FPT, or maybe it was not from this system etc?

What do you need fixed, and or how are you flashing (And have you confirmed you CAN flash that way)?

@Lost_N_BIOS
dear i know how to extract dell .exe package via DELL BIOS EXTRACTER and get bios region from it.some time we get me region & orom files with it
& some time only biosregion. if need only bios region we can replace it via uefi tool but size should be same correct?
in my previous post i upload my working dump & service tag of laptop for download right bios.
my problem is that some time my laptop shows blue screen death & some time its not detect my m.2 ssd. i checked all hardware like m.2 ssd, ram,reinstall os etc. but problem same. so i decide to make clean bios with help of .exe which dell provide according my laptop model.
after extract dell .exe package problem is as i mention previous post.
i backup my spi eeprom with ch341a & clean me region but problem same. so i decide to replace it bios region. but here actually problem occurs bcoz
after extract dell .exe i got bios region size small than my old backup.so i cannot use uefi tool here.i try fitc tool.
with help fitc i made bios without any error so i flash it to my spi eeprom with ch341a & paste it om my laptop board but got no display.
i again flash my old backup which i send to you got display ok.
now i think you understand whole steps which i did.
may be dell extractor is not extracting whole size of bios region.may be error in dell bios extractor script?
here is link where i download .exe

@earthoo7 - What I said above applies directly to Dell BIOS, not always can you get BIOS region etc from HDR and directly use like I mentioned. Some yes, but not all, that was my point.
Obviously this is one of those cases where you cannot directly use the HDR extracted files, or "BIOS region" would be matching size. I confirmed by checking, this needs manually rebuilt volume by volume, if you want to use anything from the HDR extract
HDR extract is missing one volume, one padding, and both NVRAM areas, so cannot be used as a direct insert/BIOS region swap etc.

BSOD can be anything, memory going bad, CPU going bad, video card going bad, bad drivers or programs, system too hot, failing HDD etc. Rarely, unless a big, is BIOS cause of BSOD.
Best to start troubleshooting by running Memtest86+ for 10-12 hours at least, to see if you have any memory errors.
If no memory errors after extended test, , then I would next test a clean OS install without any drivers or updates etc, and use that for a while and see if still BSOD or not. If not, then you know some program, driver, or update is causing it.

Please confirm if this system has Intel Boot Guard active by running this from V10 ME System Tools Package >> MEINFOWin.exe -verbose
Show me end of that report, do you see Measured or Verified Boot enabled on Left/FPF side?
If not, I can rebuild you a clean BIOS region from the HDR extracted files, but this isn't going to resolve any BSOD issue.

@ Lost_N_BIOS
as i mention i tried to replace memory first when face bsod.but problem was same.
so i install clean os but problem same.
i cant change cpu bcoz it is bga package.
after some day my laptop does not recognize m.2 ssd.
i purchaged new one but it does not recognised.
i checked all supply & signal which are required for m.2 ssd to run on laptop board.
found all supply okay.
so last option for me only to try flash clean bios only.but what is problem for making new bios you know now.
which bios pic i upload in my previous post was original image of my bios.
i did not know about verified boot enable onn left/FPF side?(which you written in your post)
please tell me about it if possible.
in this case how can i use extracted bios region to make fresh bios please suggest me.
what steps should i need now?

@earthoo7 - Maybe M2 SSD dying then? On your new one, can you test on other board, to make sure it's not DOA? Maybe you purchased NVME/PCIE protocol and board only support SATA for M2 slot?
What model M2 did you get? Did you test OS install on normal SSD/HDD instead of M2, for now that may be best to test with until you get compatible M2

I can make you clean BIOS, but this is not going to change anything in regards to BSOD, this isn't caused by BIOS

Download V10 ME System Tools from here, in section "C" - Intel Management Engine: Drivers, Firmware & System Tools
Inside you will find MEInfo folder, from the Win32 folder, run this command and show me image of the bottom of the report >> MEINFOWin.exe -verbose

It is too many steps for me to explain how to make clean BIOS, but I can do for you, but as I mentioned above, it's not going to change anything about BSOD's

@LOST_N_BIOS
i purchase m.2 ssd not nvme bcoz my laptop has only m.2 slot not sata & other port. generally we can identify these by their physical shape nvme has singe cut & m.2 has double cut so no confusion to choose right ssd.
i try before purchase new ssd an enclouser which convert my m.2 ssd like a usb flashdrive.
in this enclouser old ssd working fine.
i will send you pic of me -verbose tomorrow. but here are one problem bcoz ssd not detected so no os available can i run meinfo utility in dos mode
with help of refus software make my flashdrive as free dos.
is m right?
as i mention in post 220 that i clean me of my working dump bios as putomania described & i get display okay.
but my ssd not detected all other things working means detected bcoz these info showing in bios setup.
now i have only one step remain that i can change my bios region with new me.
but i m not able to create same size bios region as old one.
now i want to know how we make same size bios region from dell .exe & help of old backup
please describe...

@earthoo7 - Maybe not compatible with your enclosure then?? Does it work in that enclosure on other system?
Yes, you can run MEFINO from DOS

Sorry, not sure what you are talking about for clean ME FW, this is not related to anything we're discussing here?

New BIOS region will not help anything here. Flash in that BIOS using normal method and you will get same result, no change to BSOD issue. As mentioned, it's too involved and too many steps for me to explain how to do this manually (OK, I describe below briefly)
You need to dump your current BIOS region with FPT and send to me first too, NVRAM from it will be used (ie put into) in the rebuild BIOS region, and probably one padding area too if it contains your system info (serial etc)
Unless you want me to use the programmer dump you sent me, but it's dated from 2016??

General how to >> Use UEFItool 25 for edit/insert + 51 or above for extractions - Edit your dumped BIOS region, leave NVRAM + first padding + E34AEDB0-BB97-49BC-B139-1E419B3560E2 in place (do not replace those with anything from stock)

Open programmer dump or BIOS region dump in UEFITool 51+ and open 1_System_BIOS_with_BIOS_Guard_A.19.data.payload in UEFITool 51+ side by side
On 1_System_BIOS_with_BIOS_Guard_A.19.data.payload, extract each volume one by one as-is
On programmer or BIOS region dump with UEFITool 25, replace volumes 1-3 below E34AEDB0-BB97-49BC-B139-1E419B3560E2 (ie replace FD44D4FE-239B-4C57-B96D-E47E066A50A3 + 4F1C52D3-D824-4D2A-A2F0-EC40C23C5916 + AFDD39F1-19D7-4501-A730-CE5A27E1154B) from above extractions.
Then save as working.bin
In UEFITool 51+ expand BIOS region and get start offset of final volume, this will differ depending on what you are working on (full BIOS programmer dump, or BIOS region dump, so be careful and make sure you are at correct location when you do hex insert)
Open working.bin in hex editor, go to above offset, open final volume you extracted from stock in 2nd tab of hex editor, select all, go back to working.bin and paste last volume in place at the correct offset. Save file
Open working.bin in UEFITool 51+ and make sure FIT Table is populated and not empty/blank, AND that Parser tab of 1_System_BIOS_with_BIOS_Guard_A.19.data.payload and working.bin match same/same
If Boot Guard is not enabled (no measured/verified boot on left FPF side when you check with MEINFO -verbose), then flash or program in your working.bin
