BIOS image for the MSI Z97-S01 PC Mate desktop motherboard, sized for an 8 MB flash chip according to the name, compressed into a 6.15 MB RAR. Desktop boards of this kind store firmware on a socketed or soldered SPI chip that can be rewritten with an external programmer when the board fails to post after a bad update. Dump and keep the existing contents first so serials and MAC data are preserved, and verify the extracted file is exactly 8 MB so it fits 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 @Laptopbiossolutions. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
