Hello,

I already tried that bios version (F.21) and our projects still doesn’t work. I’ve 84A6 motherboard on this notebook. I need stock bios version because our project worked perfect until I update the bios version. 

Thank you

Hi @Volcano21

I'm afraid, F.21 Rev.A and F.22 Rev.A are the only 2 BIOS versions listed on the Software and drivers page. 

Thanks!
