Hi!! Trying to modify my AMI 4.6.4 bios from a QNAP NAS. Is this BIOS an APTIO 4 version? Tried different programs AFUDOS / Uniflash to save BIOS in order to start editing with different results and file size (some saying that the bios is write protected). Have also tried to use MMTool with error message 100003h and UEFITool A57 but not sure which ROM is a true copy that would boot after modding. Anyone with experience that could guide me? Thanks in advance.
