Working BIOS dump in a RAR archive for a Sony notebook motherboard with the Quanta code DA0HK9MB6D0, revision D. DA0-prefixed numbers are Quanta's PCB identifiers, and the board revision printed near the code should match before flashing. Extract the image and confirm its size equals the SPI chip capacity. It can then be written with a CH341A or similar programmer to fix corrupted firmware or no-post faults. Always save a dump of the original chip first, as it may hold serial or other board-specific data.
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 @pkbiosbdv. 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 →
