Original backup firmware dump labelled with BID 08BB5 and marked as fully working, packed in a rar archive of about 6.90 MB. The name does not state a brand, model or board number, only this identifier, which may correspond to a system or board ID used by the manufacturer. Such a dump is useful for restoring an SPI flash chip when the original firmware is corrupted. Confirm the identifier matches your machine, compare chip size with the image, and read the current chip contents before writing anything to it.
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 @skclappybios. Enginerys does not host this file.
