Extracting Lenovo Y520 BIOS from .exe
#1
Hi, 
I wanted to extract the BIOS binary for my Lenovo Legion Y520 BIOS update exe file here: https://pcsupport.lenovo.com/us/en/produ...s/ds121057

Can you please send it to me? I need to know the variable offset to set DVMT-prealloc too. I would be thankful if you could help.
Thanks.

I'm really sorry. That wasn't the correct BIOS link. This is the correct one: https://download.lenovo.com/consumer/mob...CN20WW.exe
Also, I will be thankful if you could tell me the DVMT-prealloc of the correct BIOS to set it via 'setup_var'.

Thanks a lot!
