Similar thread about z620 - [Request] NVMe BIOS for HP Z620

On my HP z820 Flashchip is Winbond 250128FVFG, a big chip with 16 pins.


Also, present jumpers (if I remember, memory lock) E14 dual pin, and J20 triple pin.

Several software possible to find to read Flash under DOS or UEFI, but I'm not sure in the fullest RAW dump.
And yes - CH341A flash writer works with similar chips (clips with 8 pin). I use it once with HP Elitebook.

@Minzak - What is your BIOS chip ID? Read it with your eyes, don't rely on software to tell you the ID. I will tell you best software/version to use to dump BIOS, you send to me, then we test the edit
Unless you already know what software can properly read and write to this chip?

@Lost_N_BIOS I searched already a little, but didn't write- if it helps:

WInbond 25Q128FVFG, it's visible on the pictures, too.

(BIOS is easy to add NVME driver, too, but problem will be how to flash back, and this you know much better

Hm, for me used hardware flash chip writer - it is easy.
But hand-made BIOS can be in the wrong format and MB can brick or revert or just not boot.
Need triple recheck, or better automate it! to build an NVME injector in the new version of BIOS.
I want to be fully secured and sure in the file before flash it. (I haven't second Z820 MB ))

@Minzak - Since system has ME jumper, put on jumper, reboot to windows three times, then dump BIOS region with FPT, do NVME edit, then flash it back.
If you are not sure, or do not trust your own NVME edit, then send me your dump BIOS region, or programmer dump if you want, and then I will do NVME mod for you

I'm waiting when arriving SOIC16 clip, and make the FULL RAW dump of my BIOS.

@Minzak - This maybe can be done with FPT, no need for programmer, unless you are worried to try and sort that way?
I don't think @gloobox ever tried to dump and edit just the main DXE volume, instead of entire BIOS region.
It should be possible, you can confirm by showing me image of this FPT output (use FPT from V8 ME system tools package) >> FPTw.exe -i
Do this with ME/AMT jumper on, after you reboot to windows three times.

@Lost_N_BIOS At last, I got the SOIC16 clip, just need soldering to wire it.
But interesting - I haven't 40 pin, "E1/JP1 SPI BIOS ME/AMT Flash Override Header", only empty pins.


I got E1 and E14 for latest MB

Jumper settings for updating boot block:
put a jumper on E14 & put a jumper on E1 (pin 1 & pin2)
- make sure to remove E14 after bios update.
- make sure to put E1 jumper back to previous pins (pin2 & pin3) after update.

But I got "FPTw.exe -i" once reboot under WindowsPE (I have only Linux and No Windows)

@Minzak
Thanks to try so many jumper work on Z820!
Actually I have tried almost all jumpers on Z620/Z420,but it still prompted error7 when flashing with FPT.

For me all jumpers is work. (for full dump read)

But I have some strange, after reboot and dump again BIOS - md5summ is different.
I think it always is similar behavior because in ME region rotated some data.
And for this reason on forums present messages about clearing ME region when making BIOSes.

Or I wrong, and each next dump must be with the same md5sum ?
I put in archive my dumps from flashrom(linux) and ftk8 fpt(dos) and some others - https://bizlevel.net/z820.tar.gz

Some strange, I can't detect BIOS chip when using 16SOIC Clip, I rechecked wire, but nothing (

@Minzak
Your bios files dumped are OK,just add the NVME module in it and flash

Do you have raw dump? I need it to check if my bios is corrupted?

Not yet, I still not found how to setup a clip to got worked dump utils.
