Maybe this gives you the correct binary: https://pcsupport.lenovo.com/ch/de/p...loads/ds038444 (open with 7zip and extract I0KT33A.bin)
If you open it with UEFITool, you can see in the information box that this images is for 2 chips, my guess is "ME region" for the smaller EEPROM and BIOS region for the bigger one. It looks very similar to your two binary dumbs (if you concat them).
You could extract the BIOS region by right clicking and selecting "Extrect as is...", but be aware, i'm just guessing here.. you can brick your systemComment

CPU I3-3220
HDD SATA 1Tb

And on MB found that numbers:

B888E39B6456
MB: VBA00 LA-9301P REV:1.0

Hi all,
This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.
I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

Hi everyone,
I’m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.
The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.
I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip – and the last 2MB in those files are just FF FF FF....
✅ What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575

Dear all,
I have a ASUS ZenBook UX480F with the following symptoms:
I suspect it is a BIOS issue. So I decided to try to clean the ME region. I followed the guide on win-raid, and I believe I have done everything correctly. My problem is: when I open the outimage.bin in ME Analyzer, it says that it is Extracted, and not Region, Extracted as it should be. Is it normal, or did I do something not correctly? This is my first experience editing BIOS files.
I would appreciate if someone could take time to explain the issue, so that I can learn. But I would... -
The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
Troubleshooting Attempts:

Dear all,
I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.
Here the steps I have taken to fix the laptop:
- downloaded latest BIOS from Lenovo Website...
