Firmware archive named only by the Quanta board number DAQF2AMB6A0, with no brand, model or version given. Quanta uses the DA-prefix pattern, and the trailing A0 typically identifies the board revision, so compare it with the PCB print. The RAR is 2.79 MB and should contain a BIOS image for programming the SPI chip. Save the original dump first, confirm the image size matches the chip, and verify the laptop model because one Quanta board can ship in several units.
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.
