Hi,
on the Bottom of the Motherboard are two BIOS Chips,
GD25b127 in SOP8 and GD25b256 in WSON8.
Which one needs to be flashed ?
The unzipped Official Firmware contains two Files,
FWUpdate.cap 12 Mbytes and FJNB2F4. CAP 18 Mbytes
Which is the right one ?
How can I convert it to .bin for HC341 Programmer ?
Thank you

Thanks,
I think You're right. Motherboard number is hidden under the left RAM bar (CP829256-01).
Photos on the net show a second Biochip on the back side of the board.
Now I need a suitable biosfile....Leave a comment:

Thanks for the answer.
The Fujitsu update BIOS for E5412 is common to all the models mentioned.
Unlock tool doesn't work, no hash provided after typing the 3 certain passwords.
I only found 25Q80DVSIG next to the BIOS battery.
Am I right?
Please view pictures.
