The remaining 32mb is not bios you don't need to program it
Thanks for the answer and for the help!) But on this BIOS build, the power button blinks three times and that's it. There is no reaction to the power button.
 
On the old BIOS it turns on, there is a reaction to the power button but there is no initialization. The Caps Lock and Esc lights are on.
Hello! Maybe all the same there is some way to help fix the original BIOS? Today I tried to flash the original BIOS file and as a result the laptop showed a picture with the message Self-Healing, but at 40% it gave an error and everything, again a black screen...
 
The same thing turns on, there is no display. I want a different bios, but no other bios turns on the computer. I have another board that works, but no bios turns on with it either. Do you have an idea why no bios turns on these boards. Thank you very much for the service

I think you need check hardware
 
I have a 100 percent working motherboard that I'm testing and burning a bios from here and it doesn't turn on at all. I saw this on a Lenovo T490. Am I missing something? Only with the original bios do the boards turn on
