Archived BIOS for a desktop board code-named Angelfish MT, board number 16509-1, a numbering pattern used by Wistron for Dell systems. The name includes MF1G8 with a revision letter, likely the Dell part number, and states the dump is tested working. Unpack the RAR and program the image to the SPI flash with a programmer to recover boards with no POST or corrupted firmware. Match the board number on the PCB and keep the original dump, as it holds the service tag and system data.
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 @biosarchive. Enginerys does not host this file.
