[Request] D3417-A2 - BIOS Unlock + PCIe Bifurcation

Hello all,

I’m requesting bios unlock / Bifurcation function add.

Manufacturer: Fujitsu
Model: D3417-A2 (Celsius W550)
Bios Revision : R1.33.0
Bios Date: 09/29/2021
Bios Type : AMI UEFI BIOS, export from Mainboard D3417_A2.zip (8.0 MB)
Bios Link official Page: https://support.ts.fujitsu.com/IndexDown…1FD27064D1
Bios direct download: https://webdownloads2.ts.fujitsu.com/download/FileDownload/fileDownload.aspx?SoftwareGUID=1BDE9EC5-0CFD-4800-BB8C-8D1FD27064D1&FileFolder=Downloadfiles&FileTypeExtension=ZIP&FileNameClient=FTS_D3417A2xAdminpackageCompressedFlashFiles_V50011R1330_1259662.ZIP&Token=KikmKiYrKSstJiorJiwuJSk=

Sys specs:
OS: Unraid
CPU: E3-1270 v6
RAM: 64GB ECC
GPU: GTX 960 2gb / rx480 8gb / rx6600 8gb

I dont know if the Bifurcaion function is included in this Bios, i cant find it. Can you enable it?

In this Fujitsu Bios of another Board (D3644-B1) Bifurcation sems included.

Hi Bazz,

Did you managed to activate bifurcation on your motherboard? I am trying to do the same thing on a similar Fujitsu board (D3402).

Thanks!

@StancuFlorin, not jet, it’s in progress.
I have bought a second MB, next step is to desolder the SPI Flash secure the bios as binary file for further Modificationen.
I will solder a DIP8 socket to the Mainboard to use 25QI28FVIQ Flash.

@MeatWar, I have read the Tutorials and learned that I have to export the actual Bios as Binary file, and that is my next step. I will not risc my working Machine so I’ve bought a spare MB, currently Im waiting for delivery…

Good choice… i definitely do not advise these kinds of mods on a primary system, due to risks associated to the operation.

Hello,

Here is a small update.

It was not possible to read the Bios while attached to the Board.
Next step was to desoldered it and “convert” to DIP8.


Read was now successful, so I added the DIP8 Socket to the MB and testet the old chip, it still worked.
I Flased a new Winbond Dip Flash and it worked too.

The next step will be the actual Bios Modding.

Greetings BazzT

Nicely done, go for it.

Hello,

Next update, i have enabled the “Admin” Part under Advanced in the Bios by switching to “Extended User” under Access/Use. It can be done for all subpoints that you want / need to access.
Now i can change PCIe Speed / With / … but there is no Point to change the Bifurcation setting like written in the examples.

Screenshots of the actual Bios “Setup Configuration”:




There exist Strings that discribe the usage of a Riser in the PEG Slot, but it seems not implemented in the Bios version. The Tokens cannot be found the Setup Configuration.

Is there a way to add this functionality to the “Setup Configuration”?

Otherwise I have to take the bad route :face_with_symbols_over_mouth: → PinMOD described here for old socket
10th Generation Intel® Core™ Processors Datasheet Page 27
CFG5 and CFG6 need to be 0 (LOW) for x8 + x4 +x4
Conductive and kapton tape is ordered :face_exhaling:

Hello,

conductive tape arrived and i used the G4400 to pinmod.
Not beautiful but it works. Ive cut the copper tape with a scalpell.


Next Boot the x16 slot was bifurcated to x8+x4+x4 and the cheap china riser worked.

Sadly Bifurcation can not be changed trough BIOS, we have to motify our CPU or Socket or Mainboard…

Hi, have the same PC, used as server. Had an CH341A programer, can read the bios file (clips are working well). FIle size is 16MB. Tried to open with AMIBCP - got an error - “platform identificarion failed”, as i’ve found BIOS is locked.
On the other side - there is BIOS file on the Fujitsu support page, that can be modded, has structure (opened with UEFITool NE).
Is it safe to flash via programer or (tool like AFUDOS ) modded BIOS file from Fujitsu site? Or there is a tool or specified version of AMIBCP to open ROM, readed by CH341?
