Working BIOS image for the Biostar B85 S3 Hi-Fi desktop motherboard, an Intel B85 chipset board, stored in a 4.93 MB ZIP. A clean dump like this is used to recover a board that fails to POST after a bad update or a corrupted flash. Extract the archive and write the image to the SPI chip with an external programmer, or a vendor flash utility if the board still boots. Read and keep the original contents first, since they may include the MAC address, and ensure the file size matches the 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 @biosarchive. Enginerys does not host this file.
How to open a .zip file
