BIOS file set for the AN-M2 board, packed as a 370 KB zip. Only the model name is given, without a version number or flash chip details. Note that a separate AN-M2HD variant exists, and its firmware should not be mixed with this one. A technician uses such an image to reflash a corrupted BIOS chip with an external programmer or through the board's own update routine. Always back up the current contents, confirm the exact model printed on the PCB, and verify the written chip against the source file afterwards.
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.
