BIOS archive for Quanta board DAX8QMB38A0 revision A, with no laptop brand or model given in the name. Quanta encodes boards as DA followed by a project code and MB, and the full string is printed on the PCB, so matching it is the main way to check compatibility. The rar most likely contains SPI dumps for recovering a bricked board using an external programmer. Make sure the revision letter agrees, back up the existing chip, and confirm the image size fits the flash chip before programming it.
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 @jdbios_world. Enginerys does not host this file.
