An 8 MB ROM image identified only as an American Megatrends AMI firmware with the number 9909, which may be a project or build code. The name does not state the laptop, desktop or motherboard it came from, so its target cannot be confirmed. An image of this size matches a 64 Mbit SPI flash and can be opened with AMI tools such as UEFITool to inspect modules and version strings. Identify the board from those strings and the PCB before flashing, and keep a backup of the original chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @abgm_manutencao_bios. Enginerys does not host this file.
