HeroBox GB3B Intel Gemini Lake N4020 BIOS

Hello,

I am looking for a BIOS download of the latest version for the HeroBox GB3B Intel Gemini Lake N4020 motherboard.

Thanks!

Could you please senbd your Serial number.
Also why would you want to install BIOS?. It may leave your computer with problems.

The serial number in the BIOS is: AG402A3207000167

I understand the risks in updating BIOS, please provide the latest.
Thanks.

I need the serial number of the machine, not the BIOS .
