Hello, I got a new notebook and it came with the terrible Nvidia optimus. In the past I managed to modded bios to unlock the BIOS menus in my previous notebooks. But now I'm have to learn everything again... My notebook is a MSI GE62VR, it has Aptio V AMI BIOS (not UEFI) which I was able to extract with 5.08.02.1189, modified with AMIBCP 5.01.0014. When I tried to flash I got BIOS checksum error (AFUDOS and AFUWIN). I tried one unmodified dump and got same error. For every dump I got a different checksum. Anyone can tell me what's wrong? Thanks!
