An 8 MB BIOS or firmware image whose name gives nothing beyond its capacity, so no laptop model, board number or chip is identified. The size matches a common 64 Mbit SPI flash chip such as the 25-series parts used on many notebook and desktop boards. Before writing it with a programmer like a CH341A, read and save the original chip contents, confirm the chip capacity is really 8 MB, and verify the source board matches yours, since a dump from a different board will not boot.
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 @bioshub. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
