BIOS dump packed as a RAR archive for a laptop marked G450, built on a Compal LA-5081P motherboard. The name gives no revision, flash chip type or note on whether the image was tested, so open the archive and inspect its contents before use. LA-numbered boards follow the Compal ODM pattern, and the code printed on the PCB should match before you write anything. Read and save the original SPI chip with a programmer first, and confirm the image size equals the chip capacity, since a mismatched dump will not fit.
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 →
