Sorry for my ignorance, how to flash it using a flash drive?
My current bios [URL="https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-z-series-laptops/z51-70/80k6/downloads/driver-list/component?name=BIOS%2FUEFI&id=5AC6A815-321D-440E-8833-B07A93E0428C"]C2CN21WW(V2.02)[/URL] doesn't detect the AMD gpu r9 m375, and each time I try to install any version of AMD drivers, the laptop freezes and when I force power off then start it again,either it goes to recovery options or it just a black screen after lenovo logo.
I made a FreeDOS bootable flash drive...
