RULES UPDATE for BIOS requests/offers AVOID BANNING, READ BEFORE POSTING
https://www.badcaps.net/forum/troubl...before-posting

You MUST:

• Provide the full machine model number, serial number (or Service tag, SNID) and the board model number (see https://www.badcaps.net/forum/showthread.php?t=88758 ) ,The serial number, make, full model number, motherboard model and revision (except QR codes) must be written/typed at your request as per the rules. Not as a picture, part of the file name and so on.

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 system

Thanks for help, but I'm afraid this too complicated for me.

That's the problem.

Configuration number 57310941
MO: CS02120315
CPU I3-3220
HDD SATA 1Tb
RAM 8G DDR3

And on MB found that numbers:

B888E39B6456
MB: VBA00 LA-9301P REV:1.0
