@Rothwang - The programmer they mentioned is cheap, you need CH341A + SCOI8 / SOP8 test clip with cable.
And we have guide with lots of images to show you how to use it - [GUIDE] Flash BIOS with CH341A programmer
That may or may not be required to flash mod BIOS, but it is certainly suggested to have, to make a backup first before you do anything, that way in case it bricks you can recover easily.
Please link me to your BIOS download page
Thanks very much to MeatWar, lfb6 and Lost_N_BIOS!
Following your advice, I decided as a precaution to purchase the entire CH341A + SCOI8 / SOP8 test clip with cable kit. Do you have to recommend a particular store and a particular model of these devices, or can I buy them at random on Ebay?
This is the chip to be modded[[File:Chip BIOS (4).jpeg|none|auto]]
@Rothwang https://www.macronix.com/Lists/Datasheet…4Mb,%20v1.4.pdf
Normal 3V chip, should work with asprogrammer 1.4x for example 
PLease remember to run these commands (*** according to DOS/WIN/WIN64/EFI version):
“FPT***.exe -i” => Post the complete output
"FPT***.exe -d spi.bin", this would dump the complete bios, if that’s an error try the following commands, they could give you the different regions of the bios chip:
“FPT***.exe -DESC -d fd_reg.bin”
“FPT***.exe -GBE -d gbe_reg.bin”
“FPT***.exe -ME -d me_reg.bin”
"FPT***.exe -BIOS -d bios_reg.bin"
Those commands do just ‘read’, you can’t destroy something by running them.
Ok thak you. But which kind of CH341A SOIC8 SOP8 test clip with cable kit should I buy ? Do you have to recommend a particular store and a particular model of these devices, or can I buy them at random on Ebay?
In my opinion it’s all the same cheap stuff. Normally I like to buy things which can still be repaired after 20 years in a good shop which might be a more expensive, too- but for those programmers that’s not meaningful unfortunately. ‘Better’/ more expensive shop would possibly mean less discuccion if it doesn’t work, but item is probably identical… => I’d rather buy 2 or 3 of the cheapest sets to have some redundancy… Shipped by am… might give you more reliable delivery date, though.
Hi lfb6, I just bought the KeeYees model you recommended.

Hi everyone. As you can see from the photos I bought the device you recommended, KeeYees SOP8 SOIC8 Test Clip, and I backed up the bios with the program downloaded from the manufacturer’s website, CH341A Programmer v1.34:
then I tried with MMTool 4.50.0.23 to insert an NVME module, first the extended one and then the reduced one, but the program made me the same error messages as when I tried to modify the original Fujitsu bios.
So I tried again with UEFITool 0.28.0, following your guide:
but at this point, however, I do not know where to insert the NVME module:
Can anyone kindly help me?
If it is useful, this is the link to my saved bios:
https://www.dropbox.com/s/w82g3fqew6jn3o…upbios.bin?dl=0
- Recommend to connect the flasher not via USB- hub but directly to the PC
- Link to dump says ‘file is uploading’
- What about:
Try this:

It immediately gives me this error on the first command you recommended. If it is not strictly necessary, perhaps it would be easier to work with a graphic interface application.
- You used ME tools v15 instead of 9.1.
- The CH341 dump you provided is longer than expected and contains a lot of errors when parsed with UEFItool NE compared to the stock bios. It’s not a proper read/ good backup.
I downloaded the 9.1 version you recommended but it keeps giving me errors:
Those commands are supposed to be run on the corresponding Fujitsu system. Bios dump you posted does contain a ME 9.1 so those commands should work on such a machine.
That’s a pity since you don’t have a trustworthy bios dump to work with.
Ok. So what do you suggest me to do?
@Rothwang
- Which program did you use for reading the bios chip with the ch341 programmer?
- Did you run the fptw64 command in the booted operating system of the Fujitsu Esprimo P720 E90?
Hi guys,
i have a fujitsu board d3222-A1 and i inserted the nvme driver to the bios rom file. but i cant get the bios back to the mainboard. if i use the dosflash with the updated rom file on the bootstick, it didnt take the new one. is there any other.
I’ve found something in the manual. but i dont know how to tell at the start do insert the .rom file.
ftp://ftp.kontron.com/Services/Software_…-Tool_HowTo.pdf
does anyone has an idea? or do I need a special programmer?
i’ve flashed the bios via afudos from ami to the bios. after the second change, the board does not startet anymore. 3 times beep sounds are repeating, the display is black and i cant do anything, to flash the original rom file back to the mainboard. anybody could help me?
First of all, did u get a CORRECT DUMP with the CH programmer, lb6 said that it was a BAD dump…
Did u compared the dump contents with the spi chip contents…
Im not saying to give up…we r all aware that OEM bios r sometimes very tricky to mod do to their own structure bios file, unaware of little things that we do not have knowledge.
As i said earlier its always a risky operation, specially on this OEM machines, as u saw in the pdf provided…they do advise not to use AMI tools, AFUDOS flash may not know to flash it properly and fails.
On the other hand, the FSC EFIFLASH may not accept ur mod file or only works with the partial bios update files from FSC.
Well if u have a correct dump from early state as functional, i do suggest ur CH program it again and start over.
