Hello,
I would finally like to understand how to modify a bios file in order to repair a computer by myself.
For this example, I have an Asus ROG Strix G15 (G512LV) that gives a black screen. I made a dump of the bios, I took the original bios from Asus, I compared the files, replaced the NVRAM “zone” in the dump with that of the original and reinjected the file. Result: black screen.
Maybe the problem comes from elsewhere but in doubt, I would like to know if someone can check the file that I modified in order to tell me if I did the job well please?
Thank you
