BIOS package for the base AN52 motherboard, packed into a 376 KB zip. Version and flash chip type are not part of the name, so review the archive contents after extraction. Separate files exist for the AN52S, AN52V and AN52D variants, so match the board exactly. A firmware image like this is used to reprogram a corrupted BIOS chip, through the vendor utility or with an external programmer. Dump the current chip first as a backup and verify the programmed data 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.
