BIOS dump archive for a Quanta motherboard marked DAX73AMB6F0, revision F, project code X73A. The name does not say which laptop brand or model uses the board. Quanta encodes the project in the DA-number, so the board label is the main check here. Before writing anything, read and save the original SPI flash contents with a programmer such as a CH341A. Then compare the image size with the chip capacity, because a dump that does not match the flash chip will not fit or 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 @biosarchive. 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 →
