I like to boot Grub from HDD in AHCI modus, but I can't get it working with the defaults for now. It only last until I power off the system.
Where I could obtain the option roms for AHCI and the IMC firmware. Do I need to contact AMD or is it possible to extract it from the UEFI? I only have had success with the video bios and PXE.
Best regards, Reiner
