[Request] Adding 7th Gen CPU support to Fujitsu D3430-A1

[Mamouth_74]

Hi, I purchased a FUJITSU ESPRIMO D556/E85 a long time ago.

It currently has an Intel® Celeron® CPU G3900 (Spec code SR2HV) installed and I have a spare i5-7500t (Spec code SR337) that i would like to put inside.

Thing is, the FUJITSU ESPRIMO D556/E85 motherboard (D3430-A1) only supports 6th gen while is conterpart FUJITSU ESPRIMO D556/2/E85 motherboard (D3430-U) supports 7th gen (cf: https://cdn.cnetcontent.com/d1/1e/d11e89...ddf840.pdf)

They both run the same chipset but have two different motheboard model.

Mine (D3430) has a BIOS update that you can find here:
https://support.ts.fujitsu.com/IndexDown...53DD334A7E

while the one supporting 7th gen(D3430-U) has a BIOS update that you can find here:
https://support.ts.fujitsu.com/IndexDown...A1569244B6

While i tried putting my i5-7500t in the slot, it would not boot. The cpu would just get hot but nothing would show on screen.

I was tempted to try and update by D3430 with the D3430-U BIOS update but my knowledge in BIOS is really weak and I would prefer not to brick my Motherboard without anyone's advice.

What would you suggest ?

Regards,

Just truncate D3430-U1.UPD to 8192 KB and flash by a hardware programmer.

Am I supposed to flash the truncated .upd file ? I was thinking about using a ch341a.

Desired CPU compatibilty from (microcode donor): FUJITSU ESPRIMO D556/2/E85+ (MoBo model D3430-Ux, Latest BIOS from manufacturer) can run 7th gen. Intel processors

My (slightly older model) PC: FUJITSU ESPRIMO D556/E85+ (MoBo model D3430-Ax, Latest BIOS from manufacturer) can not run 7th gen. besides running same H110 chipset and similar MoBo.

Hi guys,
I fell into some issues with the Fujitsu Esprimo D556/E85+ (MoBo: A3430-A14 GS 2). It runs an Intel G4400 CPU (6th gen.) without issues. I`ve seen online same PCs running 7th gen. processors (as it`s got an H110 chipset, I thought it would be plausible), so I bought an i3-7100. Unfortunately it doesn`t start. So I went to the Fujitsu CPU compatibility list, and bought another CPU, an i5-6500. Doesn`t run either. After some research I found some guys running into similar problems have modded the original Fujitsu BIOS with upgraded microcoede for gen.7 processors, unfortunately I haven`t found ready-to-flash file, so I ask you kindly to help me with that matter. Maybe you have that BIOS ROM-file ready to post here, or maybe you can guide me through the modding process.

CPU compatibility list for both MoBos.

and bought another CPU, an i5-6500. Doesn`t run either.

Check it with other motherboard.

*I need few days for doing that, after checking back and forth with all these CPUs unfortunately I run out of thermal paste (I like to use good/proven one, like the Noctua NT-H1). Ordered fresh one today, but expected delivery is on the 4.10.2023 (would come on 2.10. normally, but that day I took off, and that is because 3.10. is independence day in Germany). So can't do the screenshot now.

Check it with other motherboard.

*Only have this Fujitsu D556 and another mobo for 4th gen. Intels, so no possibility to check at this moment. I will ask some friends if someone else runs on LGA1151. Also, the seller assured me he tested the processor before shipping. 


Meantime I also tried your suggested solution from another post on same BIOS, but I failed (yes, I bought this "CH341A pro" J-Tag only for that purpose, I am struggeling with these CPUs for some time now....). (Thats the reason why the thermal paste went gone too, haha.)
Not sure if I should post the detailed results here in this thread, or should answer in the other thread. I am not very familiar with posting on any forums (somehow barely needed that tool in the past), sorry about that.

Thank you for your support that far anyway!

Use trunc.exe in Windows:
trunc D3430-U1.UPD 8388608

Use trunc.exe in Windows:
trunc D3430-U1.UPD 8388608

Itried but I think I made wrong file size.
I used CH341A Pro. The chip on the MoBo was W25R64JVSSIQ. I did not find same chip in Neoprogrammer repository, so I chosse a close one. Dont have the trunc.exe file in Windows10 Pro, nor does this software work when I copy it on my HDD. So I used another method: fsutil.exe. After truncating I was able to programm the EEPROM with this *.UPD file, but after the flash the BIOS went dead (no problem as I got the contact pliers, and I made backup, and I have another 2 PC with same configuration...)
I think I truncated to 9000000 or something....my bad
I will try to correct in few days when I am back at home.
Once again, I appretiate your help, DeathBringer!
