[REQUEST] Ideapad 330S-15IKB miss informations on bios.

[kurtspirit]

Hello, 
I have changed my motherboard (buy from Aliexpress...) and  have a ery big problem with keyboard :all the numeric part doesn't work anymore. I see on Google search that happen when MTM and other informations aren't wrote on Bios. I check it and it's my case. 
My question : is -it possible to add informations in bios ? I see some guys talk about LVAR64 tool but i'm not sure and i don't find it. 
My laptop is : ideapad 330s-15ikb.  
Other question : how to extrat bios file from my actuel board please?

Thank you very much.
Jonathan
