Generic BIOS archive in RAR format, 3.37 MB, whose name states nothing beyond the word BIOS. Model, brand, board number and firmware version are all missing, so the contents must be identified before any use, for example by looking for model strings inside the image with a hex editor. Dumps like this are written to a laptop SPI flash chip with a programmer to recover a dead board. Never write an unidentified image without first backing up the original chip and matching the board.
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.

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 →
