Hi
@Mini_Me , sorry, but i need some help.
I had to buy a new motherboard (BIOSTAR H410MH) and processor (CELERON G5905) because my old desktop stopped working and i was using one server (linux only) to do my tests, but i realized that i need windows to flash the card.
I modified the values with MPT and RBE, according to your points in your tutorials, and flashed with amdvbflash 3.0.4+ correctly. After restart, the system doesn`t boot, it beeps but only an underscore is shown in the screen (onboard vga). The system uses UEFI with CSM disabled.
Do you have any hint to help me save my only card?
Thank you for your time.
